Jump to: Spoilers (6)
  • In the first draft of the script, Marty's middle name was "Hopkins".
  • In the alternate timeline, George McFly is murdered on March 15, the Ides of March. This date was made infamous by the assassination of respected Roman leader Gaio Giulio Cesare (Julius Caesar) in 44 B.C.
  • Griff Tannen's car in 2015 is a modified six series BMW.
  • In the DVD extras of Back to the Future Part II (1989), Robert Zemeckis had said that he really did not want the movie to take place in the future. That is because he felt that every time that a movie takes place in the future, it is mis-predicted.
  • Elisabeth Shue was cast as Jennifer, and all the closing shots of Back to the Future (1985) were re-shot for the beginning of this film. Claudia Wells (Jennifer in Back to the Future (1985)) was unable to reprise her role, as she had stopped acting because her mother had been diagnosed with cancer. She returned to acting for the independent film Still Waters Burn (2008).
  • Cheryl Wheeler Duncan, stunt double for Darlene Vogel, was injured during filming of the hoverboard sequence when, due to a technical mishap, instead of flying through the fake glass in the courthouse, she careened into the concrete pillar and then dropped thirty feet on to the concrete below. They didn't re-shoot the scene, and you can clearly see her hitting the pillar and falling to the ground in the final film.
  • Biff Tannen's rise to fortune occurred in 1958 (not in 1955), as mentioned during the Biff Museum's video presentation. Biff would have been seventeen going on eighteen years old in 1955. Too young to legally gamble, he had to wait until 1958 (when he was twenty-one years old) to get into the race track to place any bets.
  • When the future Marty McFly attempts to play his guitar, he plays part of the main riff of "Power of Love" by Huey Lewis and The News, the theme song for Back to the Future (1985). This was the song that he had played in the first movie when auditioning for the high school dance.
  • Several elaborate sequences were deleted through various revisions of the script, including: During the 2015 hoverboard chase, Marty grabs on to a flying car that actually pulls him into the sky to a very high altitude. When Marty loses his grip, he is rescued by Doc in a flying van. Marty and Doc, after learning when Biff received the almanac, have to escape in the DeLorean during a police shoot-out. When the car's flying circuits are damaged by gunfire, Doc plunges the time machine straight toward the ground in order to reach eighty-eight miles per hour. While Marty and Doc try to recover the almanac, the fusion generator (and in later revisions, the time circuits) is damaged by Farmer Peabody (a character Marty encountered in the first film) who still thinks the DeLorean is a space ship. With Mr. Fusion and the flight circuits heavily damaged, Marty and Doc fly the DeLorean into an array of power lines over the Grand Canyon to generate enough power to return to 1985.
  • The biggest effect of the picture is a camera trick called "vistaglide". There are four scenes that use the effect of the same actor interacting with themselves. The four scenes that were shot were Griff and 2015 Biff in the Cafe '80s, the dinner sequence in 2015, 1955 Biff talking to 2015 Biff in the garage, and 1955 Doc talking with 1985 Doc. In order to create the dinner sequence with the vistaglide, the camera had to be divided into thirds and Michael had to come in three different times to play his older self, Marty, Jr., and his daughter Marlene. This is the first film to accomplish interaction between the same actor on the screen twice as two different characters. If you watch closely, you'll see that 2015 Biff's hand disappears during the scene in the garage.
  • The ledge on the clock tower that Doc broke in Back to the Future (1985) is still broken in 2015.
  • Griff's "Pit Bull" Hoverboard was originally to be called "Mad Dog" to foreshadow his character in Back to the Future Part III (1990).
  • Doc mentions to Marty that he visited a rejuvenation clinic in the future to make him appear younger. This was written so that Christopher Lloyd would not have to constantly wear old-age make-up for the two sequels, since he would primarily be portraying the 1985 incarnation of Doc.
  • A scene in which Marty meets his brother, Dave (played by Marc McClure), in the alternate 1985 was eventually cut, because Wendie Jo Sperber (who played Linda, Marty's sister) could not reprise her role, because at the time, she was pregnant.
  • Biff's alternate 1985 incarnation was loosely inspired by Donald Trump, while Lorraine's was based upon Tammy Faye Bakker.
  • An earthquake struck during filming of the cut sequence where the 2015 McFly family gathers around the table, and the crew was afraid the props may have moved around too much to edit the scene seamlessly. To their surprise, everything was exactly where it was supposed to be for the sequence.
  • The Wild Gunman (1984) video game in Cafe '80s was specially made for the film. Wild Gunman was an actual light gun game for the Nintendo Entertainment System, but was never a dedicated arcade cabinet. It was, however, included in many of Nintendo's Play Choice 10 machines, hence why a lightgun was on the cabinet. The sound effects heard in the movie are from the game, but, the on-screen graphics are entirely new, drawn to resemble what appeared. Ironically, the actual game itself had far better animation.
  • Doc mentions that he left Einstein in a suspended animation kennel in 2015. This line was written to explain why Einstein was not with Doc when he came back to 1985 to pick up Marty and Jennifer, since in Back to the Future (1985), Einstein had gone with Doc into the future, but was not there when Doc came back at the end of that film and the beginning of this one.
  • The closing scenes of the first movie were re-shot as the opening scenes of this film. Several changes were made, especially in Christopher Lloyd's delivery of his lines.
  • According to the sign hung above the front door of Biff's house his grandmother's first name is "Gertrude."
  • The principal actors committed to the sequels before any scripts were written. Crispin Glover did not return, and Bob Gale came up with the idea to have George be murdered, as a way of writing Crispin Glover out of the script.
  • DIRECTOR_TRADEMARK(Robert Zemeckis): [police]: The two police officers are named Reese and Foley, which are the names that Robert Zemeckis and Screenwriter Bob Gale use for any police or government Agents in the films they have written.
  • When Doc sees the future newspaper headline change to tell him that he was "commended" instead of "committed", a headline at the bottom of the page changes from "Nixon seeks fifth term" to "Reagan seeks second term". (Richard Nixon and Ronald Reagan).
  • According to the Animated Annecdotes on the DVD, the expandable baseball bat Griff Tannen uses is a "Kirk Gibson, Jr. Slugger 2000".
  • First film appearance by Elijah Wood. He plays one of the two video game boys to whom Marty speaks in the diner near the start of the film.
  • When the DeLorean is struck by lightning at the end, it travels back to January 1, 1885, at 12:00 a.m. (as shown by the malfunctioning time circuits before the jump). At the beginning of the movie, they travel to October 21, 2015, at 4:29 p.m. This means that the total time the DeLorean has passed through during the entire trilogy, counting all the on-screen jumps, is one hundred thirty years, nine months, twenty days, sixteen hours, and twenty-nine minutes. This, however, doesn't include the off-screen jumps Doc Brown made before he returned to 1985 to pick up Marty and Jennifer (he does mention those jumps to Marty, and even shows him a newspaper from a slightly more distant future).
  • The shooting title for the movie was "Paradox". During some special features on the DVD release, it is seen used on the slate during the making of the movie.
  • In 2015, when Doc and Marty look at the USA Today newspaper and see the headline change, the following headlines and blurbs are: Across the top: 1. Slamball Playoffs Begin (Slamball would become a televised sport in 2002) 2. Cubs Sweep Series In 5 (a World Series sweep would be in 4 wins thus implying the playoffs have been expanded in the future) 3. Marshall Runs 3min. Mile 4. Washington Prepares For Queen Diana's Visit (the film was released 8 years before Princess Diana's death) On The Side 1. Man Killed By Falling Litter 2. Tokyo Stocks Are Up 3. Swiss Terrorist Threat 4. Shredding For Charity 5. President Says She's Tired 6. Queen Diana... (Repeated Headline) 7. Kelp Prices Increase 8. Pitcher Suspended For Bionic Arm Use 9. Slamball Playoffs (Repeated Headline) 10. Jaws (1975) Without Bite (Movie review of the "Jaws 19" gag in the film) Main Headline of Griff and His Gang's arrest: "Gang Jailed" "Hoverboard Rampage Destroys Courthouse" "Gang Leader: I Was Framed" Caption below Griff's picture: Gang Leader Had Bionic Overload.
  • The Cafe '80s restaurant in 2015 is a conglomeration of the storefront's two previous incarnations in Back to the Future (1985). In 1955, it was the home of "Lou's Cafe", and in 1985, it was a fitness and workout club. While the Cafe '80s is primarily a restaurant, there are people seen working out on the exercise bikes (seen when Griff tells the riders "Keep pedalling, you two").
  • Many shows from the 1980s are featured on the televisions inside the Cafe '80s, including Family Ties (1982) and Taxi (1978), which originally starred Michael J. Fox and Christopher Lloyd, respectively.
  • The original theatrical and premium cable television versions of the film end with the phrase "To Be Concluded", and a teaser for Back to the Future Part III (1990). Russ Meyer and Richard Lester are the only other filmmakers to have ended a movie with a trailer before this release. (Recent 2009 premium cable television versions have dropped the teaser.)
  • One initial idea for the sequel had the first two acts the same, but the third act had Biff giving his younger self the almanac in the 1960s, not in 1955. When Marty went back to stop him, he ran into his parents again (who were now hippies) and almost stopped his own conception. Robert Zemeckis decided that it was too similar an idea to the first film, and George and Lorraine would have been too old to be hippies. He came up with the idea of revisiting the original Back to the Future (1985) from different angles with the two Martys in 1955.
  • On his tombstone, George McFly (who was born on April 1, 1938), is revealed to have the middle name of "Douglas".
  • This movie was the most advanced film of its time for using "every trick in the book", according to Robert Zemeckis. It was in the late 1980s when the concept of CGI was starting. However, in the film, very few CGI effects were actually needed.
  • Originally, only one sequel was planned. The script for this sequel, known as "Paradox" included all the elements of this movie and Back to the Future Part III (1990), but compressed to fit into one movie. However, it was revealed with the release of the DVD set that there was an even earlier script which involved Marty meeting up with his parents while they're college students in the sixties. (This was probably dropped because no matter how you cut it, George and Lorraine wouldn't have been in college during the "Protest Era", they were too old.)
  • The football scores Biff hears on the radio while driving are all actual scores from November 12, 1955, and the UCLA and Washington game he and old Biff listen to did end with UCLA kicker Jim Decker hitting a last second field goal to win.
  • Crispin Glover sued the filmmakers, as he had not granted permission to use his likeness in Part II. Crispin's suit named John Doe 1-100 as defendants, where he did not have to name all of the individuals he was suing. Crispin ended up dropping the lawsuit after the case was settled out of court for $765,000 by Universal's insurance company, who decided it would be cheaper to pay Crispin than to go to trial. The Screen Actors Guild subsequently introduced new rules about illicit use of actors.
  • Back to the Future II Back to the Future Part III (1990) were filmed back-to-back. After filming the scene where Doc and Marty return from the future to "1985A" and drop Jennifer off on her front porch swing. After this, the cast and crew waited for daylight and filmed the Part III scene where she is awakened.
  • Filmed at the same time as Back to the Future Part III (1990). It was claimed at the time that in the four years since Back to the Future (1985) was made, Michael J. Fox had forgotten how to ride a skateboard. However, motor skills are not so easily lost (as in riding a bicycle), and Michael J. Fox has since stated that this was an early symptom of his Parkinson's Disease, although the medical diagnosis was not made until 1991.
  • (Cameo) Charles Fleischer: Terry the tow truck driver from 1955 also plays the older version of his character, who wishes he had bet on the Cubbies. Fleischer also provides the off-screen voice of Biff's grandmother.
  • When the unconscious Jennifer is taken home by the two officers in 2015, it looks as if great pains were taken to conceal the identity of the one officer (Reese). Her face is kept in the dark, and her cap is even kept to where the bill is hiding her eyes. The actress portraying Officer Reese was Mary Ellen Trainor, who was Robert Zemeckis' wife at the time.
  • The hoverboard sequences required many different special effects and camera tricks. In the shots where Michael J. Fox was on a harness, the soles of his shoes had to be permanently attached to the hoverboard. This meant that he had to be carried around in between takes of these scenes.
  • The 1990 television special The Secrets of the Back to the Future Trilogy (1990) showed some sequences cut from the film: Biff fades out of 2015 after stumbling out of the DeLorean and behind some trash cans. Marty discovers the destroyed Hill Valley High School.
  • The futuristic looking cab that takes "old Biff" to the DeLorean, while it is parked near Marty and Jennifer's 2015 house, is a Citroen DS. This car went into production in October 1955, so it could, conceivably, have appeared in the original Back to the Future (1985). The same car appears as a wreck in the "alternative" 1985.
  • We learn several bits of information about Needles during his phone call with Marty. In the order they appear on the screen, they are: -Needles, Douglas J. -Occupation: Sys Operations -Age: 47 -Birthday: August 6, 1968 -Address: 88 Oriole Rd, A6t -Wife: Lauren Anne -Children: Roberta, 23 Amy, 20 -Food Prefence: Steak, Mex -Food Dislike: Fish, Tuna -Drinks: Scotch, Beer -Hobbies: Avid Basketball Fan -Sports: Jogging, Slamball, Tennis -Politics: None
  • After Biff gets his cane stuck in the DeLorean upon returning to 2015, he starts to thrash around in pain, apparently having a hard time from the exertion. Robert Zemeckis has stated that Biff was experiencing the same thing Marty did at the dance in the first movie: fading out of history. The idea was that, by going back in time to give the sports almanac to his younger self, Biff had somehow altered his own future so that he no longer existed in the year 2015. According to script drafts, Biff's wife (Marty's mother) had shot and killed the abusive Biff in 1996. A deleted scene in the DVD extras makes this much clearer as we actually see Biff vanish.
  • In the 1985 scene where Marty watches a documentary on the life of Biff in front of the casino, there is a still photo of the part III villain, Buford "Mad Dog" Tannen. According to Bob Gale in the DVD commentary, this was a still of an early make-up test for Mad Dog. The look was changed when Back to the Future Part III (1990) began production.
  • Doc tells Marty, "Just say 'no'" to Griff Tannen, when they first arrive in 2015. That phrase was the popular Reagan Administration slogan for peer pressure among youth in the '80s. Not only was Ronald Reagan spoofed in this film, but Fox's Alex P. Keaton from Family Ties (1982) was a supporter of the President.
  • In 2015, several cars from other science fiction movies can be seen, including a Spinner from Blade Runner (1982), and the StarCar from The Last Starfighter (1984). Other cars seen are (highly) modified Ford Probes and Mustangs, as well as concept cars.
  • The image of two nude women on the large screen when Marty, Jr. says "art off" is "The Gold of Their Bodies (Et l'or de leurs corps)" by Paul Gauguin. The original is in Musée d'Orsay, Paris, France.
  • On the fax that tells Marty he's fired, the address, "11249 Business Center Road, Hill Valley, California, 95420-4345," is obviously fictional, but in reality, the ZIP code belongs to the city of Caspar, about five hundred miles north of Los Angeles on the coast of California.
  • The Jaws (1987) video game seen in the antique store window was made by LJN for the early releases on the Nintendo Entertainment System. LJN would go on to make video games based on this movie and Back to the Future Part III (1990). LJN also made the NES game based on Who Framed Roger Rabbit (1988). A doll of Roger also appears in that same window with the Jaws game.
  • Also present in the 2015 antique shop, front and center, is the video game Burgertime for NES. Burgertime which was an arcade game ported to several home video game platforms also including Mattel Intellivision and Atari 2600.
  • The production of this film (and of Back to the Future Part III (1990)) was delayed for three years because Robert Zemeckis was busy making Who Framed Roger Rabbit (1988).
  • In this movie a disguised "1985 Doc Brown" holds a conversation with his 1955 counterpart. 1985 Doc is wearing a brown trench coat and hat. If you look carefully in Back to the Future (1985), you can see a man dressed exactly like this (and therefore, presumably Doc) walking away shortly before the clock tower scene. In the DVD commentary, it is explained that this was not intentional, as the script for Back to the Future Part II (1989) hadn't even been written at the time that they filmed the first one.
  • Bits and pieces were cut out of the dinner scene. When Marty, Sr. says "I missed that whole thing", he's referring to a cut scene where Lorraine mentions that Uncle Joey was turned down for parole again.
  • Although Marty McFly comments that his son "looks just like him", there is one notable difference between the two (aside from a faulty jacket sleeve and a white t-shirt): Marty McFly, Jr. has brown eyes, whereas his father doesn't (this can be seen most clearly in the scene with Griff in Cafe '80s).
  • The principal actors and actresses had committed to the sequels before any scripts were written. However, there was a stumbling block in negotiations with Crispin Glover (George McFly in Back to the Future (1985)), who stated that he was offered a monetary amount less than half of what Lea Thompson and Thomas F. Wilson were being paid to return. Crispin believed this was due to producer Bob Gale taking exception to Crispin voicing his disapproval of the original ending of the first film (where the McFlys viewed money and material possessions as rewards), causing a script change. During sequel negotiations, Crispin's agent expressed to producers that Crispin wanted fair compensation, in addition to a script approval clause in his contract. Bob Gale refused to give in to either of these requests, instead offering a lower salary amount than the first offer. After Crispin turned down the lowball offer of one hundred twenty-five, Gale re-wrote the sequel script to lessen George McFly's screentime. Jeffrey Weissman was cast as George and, using molds of Crispin made on the set of the first film, was dressed in facial prosthetics to look like Crispin, so that they could incorporate excerpts from the original movie. All shots of Weissman either show him from behind, at a distance, upside down or with sunglasses, in effect, fooling audiences into believing that Crispin had taken part in the sequel.
  • The hotel tower for "Biff's Casino" was actually the hotel tower for the Plaza Hotel and Casino in downtown Las Vegas, Nevada.
  • In promotional material, such as Back to the Future Part II Behind-the-Scenes Special Presentation (1989), director Robert Zemeckis explained that "hoverboards float on magnetic energy". He also added, "they've been around for years, it's just that parent groups haven't let toy manufacturers make them. But we got our hands on some and put them in the movie." He was only joking, of course, but interestingly enough, Mattel (whose logo appeared on the hoverboard props) soon found themselves overwhelmed with callers asking where they could buy one. Although they looked pretty convincing in the movie, the hoverboards were simply wooden props attached to the actors and actresses feet. To make the boards fly, the actors were suspended by cables, which were then erased during post-production.
  • When "Hill Valley" was created for Back to the Future (1985), they built the town in the pristine 1955 condition, and shot the middle of the movie, then damaged it for the 1985 town, and shot the beginning and end of the movie. When they decided to shoot Back to the Future Part II (1989), they had to clean the set up and restore it to the same condition it was in 1955. It cost more to rebuild than it cost to build it from scratch.
  • When Marty arrives in 2015, he looks in the window of an antique store, where we see the denim jacket that he wore in 1985, a Roger Rabbit doll and a Jaws (1987) Nintendo game. There's also a JVC Super VHS camcorder of 1988.
  • Casey Siemaszko, who plays one of Biff's cronies, is named "3-D" because he wears 3-D glasses. In 1955, he wears the paper kind issued at 1950's style 3-D movies, but for his scenes in 1985, a pair of real sunglasses with red and blue lenses were made to better suit the era. By 2015, Griff's goons wear holographic-type shades.
  • This time travel film takes place on the night where DST (Daylight Saving Time) ends for the year 1985.
  • The casino neon sign incorporating Biff Tannen's signature was modelled after a neon sign that once stood on Bob Stupak's Vegas World Casino (now the Stratosphere) in Las Vegas, Nevada.
  • The tagline for Jaws 19 is "This time it's really, REALLY personal". On the marquee is the name of the director, "Max Spielberg", executive producer Steven Spielberg's son. Max was born in June of 1985, the same year the first film in the franchise was released. Spielberg also came up with Marty's response to seeing the hologram, "The shark still looks fake", referring to Spielberg's frustration and doubts about "Bruce", the mechanical shark in Jaws (1975).
  • The ending of Doc's departure to 1885 via weather and his ensuing telegram to Marty is foreshadowed. During the beginning, Doc commented how he wished postal delivery was as reliable as the meteorological service.
  • There are many differences that make this film unique from the other two: More time periods are visited in Back to the Future Part II (1989) than in any other Back to the Future movie: The good 1985, 2015, 1985-Alternate, 1955, and 1885. Although the last one was not visited until Back to the Future Part III (1990), the trailer for Part III is shown just before the closing credits, so in a way, it could be considered part of this movie as well. The "original" 1985, in which Back to the Future (1985) starts, is only represented for less than a second - in the Part III trailer, we see Marty and Jennifer reuniting outside her house from the end of the film. This is the only film in the trilogy that does not end with a time travel vehicle flying directly at the camera. Unless you count the re-used scene from the first movie, this is the only film in the franchise where Marty doesn't once drive the DeLorean. This is the only film in the trilogy to feature a female member of a Tannen gang. This film introduces one of Marty McFly's most distinctive and enduring character traits, losing his temper and sense of reason when someone calls him a "chicken". The only film in the franchise where the future (2015) is visited. 1985-A is the only time line in the whole trilogy that you never get to see during daylight. In other words, it is the only one, to which Doc and Marty travel, where it is night time during the whole time they're in it. Neither of Marty's siblings (David & Linda McFly) appear here. They are mentioned once by Biff.
  • Doc expresses his regret that he will never be able to visit his favorite historical era, the Old West, and suggests that instead he should devote himself to studying women. He gets to do both in Back to the Future Part III (1990).
  • Mr. Strickland's office placard identifies him as "S.S. Strickland." While it has been speculated that it stands for "School Superintendent", a photo album included with the deluxe edition of Back to the Future: The Game lists his name as Stanford S. Strickland (born 1925). The "SS" is obviously a tongue-in-cheek reference to the infamously-harsh/dictatorial German "Schutzstaffel" paramilitary organization under Adolf Hitler (i.e., the dreaded "SS") during WW2, and is a grimly-humorous reference to how excessively heavy-handed and sternly totalitarian Mr. Strickland's rule is over his students. The BTTF book identifies his first name as "Gerald".
  • The shirt that Doc wears for the majority of the film features a design depicting cowboys on horseback and a train, foreshadowing the climax of the third film.
  • Bob Gale wrote the first draft of the screenplay on his own, because Robert Zemeckis was busy filming Who Framed Roger Rabbit (1988) at the time.
  • Robert Zemeckis considers this one of his favorite, and strangest films.
  • Robert Zemeckis and Bob Gale have admitted on the DVD commentary that they were originally not interested in doing a sequel to their success hit Back to the Future (1985), and that the open ending of the first movie was simply meant as a final joke. However, when plans for a sequel were made by the studio, they chose to remain involved in the continuation of their creation, and even extended it to two sequels. Zemeckis has claimed that if he knew that he was going to make a sequel, he would have made sure that Marty's girlfriend Jennifer wasn't in the car at the end of the first film. Since the movie would concentrate on Marty, there was not much for her to do, and she would even get in his way. This is why Jennifer is knocked out by Doc and left behind so early in the movie.
  • The t-shirt that Doc wears during most of the film, that has the train and horse design, was manufactured as part of the attire for the attendants when "Back to the Future: The Ride" was running at Universal Studios Hollywood and Universal Studios Orlando. Since the ride is no longer at these attractions, the shirts have been widely distributed, and costs on the average go well beyond two hundred dollars on eBay.
  • Carl Sagan considered this the greatest time travel movie ever made. He praised the accuracy in handling the multiple time lines as what would really happen if time travel were possible. In Back to the Future: The Game, Carl Sagan is the alias used by Doc Brown when visiting Hill Valley in 1931.
  • During production, a 1:15 sized Delorean was used for several bluescreen shots at a distance. In 2008, models of the Delorean in this size were released to the public. New features included several sound bites from the films.
  • In front of the entrance to the Biff Tannen Museum, there is a sign that reads "Smoking Required".
  • As the flying Delorean gets off on the Hill Valley exit of the Skyway, a floating sign can be seen in the background, which reads "HYPERLANE - GRID 4, RN (Rain), 20% VIS (Visibility), PHOENIX : BOSTON : LONDON, LOCAL TRAFFIC HILL VALLEY EXIT NEXT RIGHT".
  • At the school dance, a member of Biff's gang, 3-D, is shown "spiking" the punch with alcohol. In Back to the Future (1985) George is shown drinking the punch before confronting Biff in the parking lot. It may be that George's uncharacteristic courage in the original scene is attributable to drinking the spiked punch.
  • In the Back to the Future trilogy, the "present" date is October, 1985 (2015 is the future, 1885 and 1955 are the past). Exactly 25 years later on October 26, 2010 the Back to the Future trilogy was released on Blu-ray in a 25th Anniversary Edition.
  • Lea Thompson (Lorraine McFly) and Thomas F. Wilson (Biff Tannen) are the only actors to play the same characters young and old in four different time periods: 1955, 1985, 1985-Alternate, and 2015. Thompson and Wilson also appear in 1885 in Back to the Future Part III (1990), Thompson as the wife of Hill Valley's first McFly, and Wilson as Mad Dog Tannen, his twentieth century character's ancestor.
  • The soda menu at Cafe '80s listed four types of Pepsi products: Original, Diet, Max, and Perfect. Pepsi Max did become an actual flavor by 1993 in Europe. The American version was introduced in 2007.
  • In the French translation of the movie, Marty McFly is called "Pierre Cardin" in 1955, instead of "Calvin Klein".
  • On September 8, 2011, the Parkinson's Research Foundation announced that 1,500 pairs of the futuristic Nike MAG shoes, based on the sneakers worn by Michael J. Fox in this movie, would be auctioned off on eBay. The first pair sold to Tinie Tempah for the winning bid of $37,500.
  • The film depicts an alternate, dystopian 1985 where President Richard Nixon is in his fifth term. This was also a plot point in the Alan Moore and Dave Gibbons graphic novel Watchmen (1986-1987). Alan Moore and Bob Gale have written for Batman comic books.
  • The date on the 2015 USA Today newspaper is October 22nd. This is Christopher Lloyd's birthday.
  • According to Bob Gale, during negotiations, Crispin Glover's agents told producers that Crispin would only agree to appear in the sequels if he was given script approval and $1 million. The producers asked Crispin's agents to come back with a more reasonable offer, or they would assume he was not interested in being in the film. Crispin refused to budge on his conditions, so Gale re-wrote the script to lessen George McFly's screentime. Crispin disputes this, saying he was offered less than Lea Thompson for a similar sized role, due to his complaints about the ending of the original film.
  • In the original script, Pa Peabody was to have been evaluated at a mental institution for claiming to have seen a spacecraft (the DeLorean in the first film). As soon as he is released, he sees a flying DeLorean and fires his shotgun at it, damaging the time circuits. This is the reason the destination time display flickers over to read 01.01.1885. On the region one DVD commentary, Bob Gale mentions the scene was dropped when Will Hare was not available to return for the sequel.
  • In the future, there's a brand called Fusion Industries visible in a back alley, it's also the brand for the new organic energy feeder of the DeLorean.
  • At Cafe '80s, there's an arcade game Wild Gunman and a Pac-Man marked "Priceless artifact, do not touch".
  • In fall of 2011, Mattel gave the announcement of their official production of the hoverboard, slated for a November or December release in 2012. The company started the promotion orders in March 2012, by taking orders that were extended into April. All the orders included a 1:6th scale of the hoverboard. Next to the other futuristic items in the movie, it's the fourth official release of a prop from the movie.
  • Very few of the original costumes from the Enchantment Under the Sea Dance were used for production of the sequel. Lea Thompson was the only actress present wearing her dress from the original movie.
  • When 1985 Jennifer discovers herself in her 2015 house, her daughter Marlene (played by Michael J. Fox) appears at the top of the stairs, saying, "Mom? Mom, is that you?" This is the same exact line spoken by Marty (also played by Michael J. Fox) in each film of the trilogy when he is knocked out and wakes up in an unfamiliar place.
  • Futuristic parking lots and curb-sides have white-painted "No Landing" zones, now that many of the "mid-2010s-era" vehicles are (or have been converted to) flying vehicles.
  • The "reverse 99" image in the sky is not intended to represent a mathematical figure that designates a number of years travelled in time; it is merely the pair of flaming "spiral trails" that the DeLorean's wheels made as it spun rapidly up to eighty-eight miles per hour after being hit by lightning.
  • Unless you count the re-used scene from the first movie, this is the only film in the franchise where Marty doesn't once drive the DeLorean.
  • When Marty walks past the antique store in the future a copy of "Jaws" on Nintendo can be seen in the window. The Nintendo game "Jaws" was produced by a company called LJN which is also the same company that would later produce the "Back to the Future" series of games that later appeared on Nintendo and Sega.
  • Elisabeth Shue is actually the third person to play Marty's girlfriend, Jennifer. Melora Hardin briefly played Jennifer when Eric Stoltz was originally cast as Marty. Then, Claudia Wells played Jennifer along with Fox as Marty in Back To The Future (1985).
  • One of the screens in the Café '80s is showing Taxi (1978), which also starred Christopher Lloyd.
  • Was the first film to be released onto videocassette by MCA/Universal Home Video.
  • Bob Gale originally wrote a script for Part II revolving around the '60s. It was re-written because when Robert Zemeckis returned from Who Framed Roger Rabbitt (1988), he didn't like it.
  • The film featured a futuristic Texaco gas station when Marty and Doc arrive in 2015. Texaco merged with Chevron on February 8, 2002 (becoming ChevronTexaco until May 9, 2005 where Chevron dropped the Texaco part of the merged company name) - at the time of the merger, Texaco business interests with Equilon and Motiva Enterprises were purchased by Shell Oil Company U.S.A., and existing Texaco gas stations in operation prior to February 2002 were rebranded as Shell. As of 2015, Texaco no longer operates as an independent company - Chevron has nonexclusive rights to the Texaco brand since 2004.
  • The original draft of the script had Doc and Marty travelling to 1967 instead of back to 1955 to stop Biff. Marty once again encounters his mother, and accidentally prevents her from going on vacation with his father, thus stopping his own conception, and endangering his existence once more. Throughout the 1967 scenes, the 1985 Doc is continuously hiding from his 1967 counterpart, but the duo requires the younger version's help, since the "Mr. Fusion" is broken.
  • In the original draft of the script, Marty does not see a marquee for "Jaws 19" when in 2015. Instead the theater lists "Godzilla 2015", almost coincidentally predicting the real-life Godzilla (2014).
  • Biff's grandmother, Gertrude, is the mother of Biff's father, Irving "Kid" Tannen, as seen in Back to the Future: The Game.
  • The guitar hanging on the wall above the video game in the Cafe '80s is the same guitar played by future Marty later in the film. It's a Paul Reed Smith guitar with a metallic blue and purple finish.
  • You can see Michael Jackson posters on the wall of the African-American's family house when Marty enters, one of them is "Off The Wall", and the other one is "Thriller", and you can hear "Beat It" in the Café '80s when Marty enters, and see an animated figure of Michael Jackson on the screen telling the customers about the menu.
  • The matchbox Marty took from Biff's office says Pleasure Paradise before it changed to Auto Detailing once he burned the Almanac magazine. This explains Biff's business when he is in 1985.
  • Third highest grossing film of 1989.
  • Ranked 498 on Empire Magazine's 500 Greatest Movies Of All Time in 2008.
  • In 1985A, the newspaper bearing the story of Doc's mental hospital commitment has a story about Richard Nixon seeking a fifth presidential term. This is believed to have been inspired by the Alan Moore graphic novel Watchmen, in which Richard Nixon is serving a fifth term.
  • Flea was touring with the Red Hot Chili Peppers and according to him, flew really far away to film his scenes, and had slept for two hours the night before. Flea shot his scenes in one day, and then flew back to the tour that night. Flea said that much of the time was a blur, save for having lost a sweater his grandmother knitted for him on the way to shooting his scenes, and that other than seeing them premiere, he hasn't seen the trilogy since.
  • The movie predicts the Cubs winning the World Series in 2015 against a team from Miami whose mascot is a green alligator. In the actual year of 2015, not only did the Cubs make the playoffs (Cubs lost to the Mets in the 2015 NLCS 4 games to 0), but so did the Royals (who won the 2015 World Series beating the Mets in 5 games) and Cardinals (the writer of Back to the Future is a Cardinals fan whose team lost to the Cubs in the 2015 NLDS), the two teams who had played Game 6 of the World Series on the night Marty went back in time - October 26, 1985. While neither the Marlins nor Rays made the playoffs, the Astros did , and their mascot - Orbit - is also green.
  • Two years were spent building the sets and completing the scripts for this film and Back to the Future Part II (1989). They were both filmed over the course of eleven months. This film was being edited while Back to the Future Part III (1990) was being filmed.
  • The film's trailer features an alternate take not in the final cut of the film.
  • Just before Marty and Doc leave 2015, there is a shot of the time machine's control panel showing the "Last Time Departed" as Nov 12 1955 6:38 p.m. If they had noticed this, they would have known someone had used the time machine without them.
  • There are four DeLorean DMC-12s in 1955 in this movie, the one from the first movie, the one that Biff is using to give the almanac to his younger version, the other is the one that Doc and Marty are using to get back the almanac and the one that is hidden in the mine since 1885.
  • George Douglas McFly was born on April 1, 1938.
  • Douglas J. Needles was born on August 6, 1968.
  • Marty McFly, Jr. was born in 1998.
  • Roberta Needles was born in 1992.
  • Amy Needles was born in 1995.
  • Christopher Lloyd celebrated his 77th birthday on October 22, 2015, the day after Doc and Marty visit 2015 in the film.
  • Near the end of the film, when Marty is attempting to steal the almanac back from Biff, they approach and eventually drive through a tunnel. This is the same tunnel private investigator Eddie Valiant drives through to reach Toon Town in Who Framed Roger Rabbit (1988), which was likewise directed by Robert Zemeckis and starred Christopher Lloyd (Doc Brown).
  • From his tombstone, we find that George McFly was born on an April Fool's Day and died on the Ides of March.
  • Multiple theaters screened the movie on October 21, 2015, as that is the exact date Doc, Marty and Jennifer travel to the future.
  • To commemorate the film, a fake teaser trailer spoofing the non-existent "Jaws 19" was released on October 21, 2015. It describes all nineteen movies as follows: Jaws (1975) "made you afraid to go into the water"; Jaws 2 (1978) "made you afraid to go back into the water"; Jaws 3-D (1983) (which starred Lea Thompson) was "a new dimension in terror"; in Jaws: The Revenge (1987), it was "personal"; "Jaws 5" was "just business"; "Jaws 6" was "pure pleasure" (suggesting a romantic subplot); "Jaws 7" was "cyber-Jaws" (suggesting the shark had gone digital); "Jaws 8" was "Robo-Jaws" (spoof of RoboCop (1987)); "Jaws 9" featured Chief Brody's grandson "assembling a super team of shark hunters"; "Jaws 10" was "man versus shark versus all the terrors of the deep" (suggesting giant squids); "Jaws 11" took place in "outer space"; "Jaws 12" was a prequel; "Jaws 13" was "Jaws 12: Part 2, a sequel to the prequel"; "Jaws 14" had Jaws "starting a family"; in "Jaws 15", Jaws "battled a Russian shark named Ivan Sharkovsky" (spoof of Rocky IV (1985)); in "Jaws 16", "Jaws took a bite out of the Big Apple"; in "Jaws 17: 50 Scales of Grey", "Jaws learns about love from a mysterious stranger" (spoof of Fifty Shades of Grey (2015)); "Jaws 18" was "the mind-blowing reboot", and finally, in "Jaws 19","the oceans are disappearing, and to save their home, the sharks must attack. This time it's really, REALLY personal!"
  • Bob Gale had the Chicago Cubs winning the 2015 World Series as a joke, due to him being a St. Louis Cardinals fan. While he did correctly predict Miami having a Major League Baseball team by 2015, the Cubs wound up getting swept by the New York Mets in the 2015 NLCS 4 games to 0.
  • Bob Gale, a baseball fan in real life, said he came up with the scene referencing a World Series Championship by the Chicago Cubs upon personally brainstorming about the most unlikely scenarios he could come up with. Gale also said he based the timing of the 2015 World Series on the usual World Series scheduling at the time of the movie's production and release. Gale admitted he erred in not foreseeing MLB expanding their playoff schedule by the mid 1990s, and pushing the World Series until later in October, and in the case of 2015, early November.
  • The headline of a newspaper shows that Doc Brown is admitted into a mental hospital in the alternate 1985 after Doc and Marty return from 2015. Christopher Lloyd also played the role of Taber, a mental patient in One Flew Over the Cuckoo's Nest (1975). He also played a mental patient in The Dream Team (1989).
  • To commemorate the film in 2015, USA Today changed their masthead to the futuristic logo featured in the film, and reissued the front page featuring Marty, Jr. getting arrested. Nike developed real-world versions of the self-tying sneakers (called Mag) and sold them with the proceeds going to Michael J. Fox's Parkinson's research foundation. Pepsico made the Pepsi Perfect bottles and sold them for $20.15 rather than the $45 Marty paid for one at the Cafe '80s.
  • According to Michael J. Fox, he found out there was going to be a sequel to Back to the Future (1985) when he watched the VHS version and the words "To be continued" were added at the end. He immediately called his agent to make sure he was going to be in the sequel.
  • The motivation for writing a scene with an automatically hydrating oven in the future was due to product placement needs with Pizza Hut's sponsorship. Pizza Hut provided a professional food stylist and pizza kitchen to be at the set of the future McFly house to make hot, attractive pizzas for each take.
  • The plot line of George McFly being dead in 1985-A was based entirely on Crispin Glover's refusal to do the sequel.
  • Screenwriter Bob Gale was inspired to write science fiction by the George Pal version of The Time Machine (1960) that he watched as a kid, and subsequently gobbled up a lot of time travel novels thereafter.
  • One of the conceptions of the 2015 universe that didn't make it on-screen because of the budget cuts was a sport called "Slam Ball", that would be played in an anti-gravity chamber, and combine Jai Alai, handball, and roller derby.
  • In the hot tub scene, the film Biff and his lady friends are watching is A Fistful of Dollars (1964), starring Clint Eastwood. This "foreshadows" Marty's alias in Back to the Future Part III (1990) and how Marty survives the shootout with Buford Tannen.
  • This is the only film in the trilogy not to include Marty's siblings, Dave and Linda (except in a deleted scene called "Marty Meets Dave" which Dave appears in). However, they are mentioned by Biff.
  • In the film the Chicago Cubs won the World Series, but in reality the Kansas City Royals were the 2015 World Champions (defeating the Mets who beat the Cubs 4 games to 0 in the 2015 NLCS). The last time the Royals won the World Series was in 1985, the year that the first film and part of this film take place.
  • The day Marty time travels to the year 2015, October 21, 2015, happened to be the day the Chicago Cubs were eliminated from the playoffs. In the film, there is a joke stating the Cubs finally win the World Series. In reality, the Cubs were swept 0-4 in a series against the New York Mets, knocking them out of the playoffs and the chance to win the World Series, although the team eventually won the World Series one year later against the Cleveland Indians by 4-3.
  • On the notion that Biff and Lorraine were eighteen in 1955, this means that when Marty encounters both in 2015, they would be seventy-eight years old.
  • Premiered on November 22, 1989, the day before the twenty-sixth anniversary of the first episode of Doctor Who (1963), also about a doctor with long white hair who travels through time in a commonplace object. Years later, the word "DeLorean" was featured on an episode featuring the Thirteenth Doctor.
  • Ranked #23 on Empire Magazines' 50 Greatest Movie Sequels in 2009.
  • To commemorate the release of a 30th anniversary Back to the Future Blu-ray box-set, a short movie called Back to the Future: Doc Brown Saves the World (2015) was filmed with Christopher Lloyd reprising his role of Doc Brown. In the movie, Doc tapes a video message, explaining that he travelled to the 2040s in a rebuilt DeLorean, and discovered that inventions such as the Hoverboard and hydrated food will cause people to become massively overweight; even worse, a simultaneous glitch in every nuclear Mr. Fusion device on the planet will cause a nuclear holocaust that decimates the world's population. He subsequently travels back in time, and successfully prevents such dangerous devices from ever being invented, thus explaining why the future 2015 as seen in this movie did not come true in reality.
  • Despite what some people believe, the voice of Marlene McFly was not that of Michael J. Fox, but rather voice actress Grey Griffin.
  • Despite both of their ancestors having blue eyes, Marty, Jr. and Griff have distinctive brown eyes.
  • Some of the items displayed in the Cafe '80s front window: Apple Computer, Black & Decker Dustbuster, Black & Decker clothes iron, JAWS and JAWS 2 VHS boxes, Dragnet 1987 VHS box, Animal House VHS box, Barbie and Ken dolls, NES BurgerTime video game, Roger Rabbit doll, Lava Lamp, JVC Television, JVC Super VHS Video Camera, Perrier Bottled Water, "Trust Me" Jimmy Carter comedy album by Hans Petersen, Bee Gees album, Ronald Reagan "Freedom's Finest Hour" picture disc LP, Pac Man lunch box, Mendocino box, Jimmy Carter poster, colorful happy faces, Sanyo Orange Phonosphere record player, Jimmy Carter peanut bank, Gray's 1950 - 2000 Sports Almanac, computer keyboard, J.F.K. bust, rounded white telephone, Magnavox Weekender radio, NES RC Pro AM video game box, and Marty's denim jacket (with pin).
  • Thomas F. Wilson (Biff Tannen) and Joe Flaherty, who plays the Western Union delivery man, would both play small parts in the television series Freaks and Geeks (1999). In this movie and the television series, the two didn't share any scenes.
  • The scene where Doc Brown arrives at Biff's house and discovers that Marty is gone, he says "Damn! Where is that kid?", his 1955 counterpart said the same thing in the original when he was wondering why Marty was late for his trip back to the future during the famous clock tower scene.
  • This is the only film in the trilogy to feature a female member of a Tannen gang.
  • The hoverboard chase scene is similar to famous skateboard chase scene in the first movie. Marty attempts to give the hoverboard back to the little girl, but she rejects it after obtaining the most powerful air skateboard "The Pit Bull". In the first movie, Marty was able give the skateboard back to the little boy.
  • Mr. Strickland is the gym teacher in 1955, as evidenced by the whistle he wears around his neck.
  • The Back to the Future trilogy, Gremlins (1984), and Young Sherlock Holmes (1985) were all produced by Steven Spielberg and all have eccentric inventors, madcap inventions, and pet dogs Einstein, Barney, and Uncas.
  • If you pay close attention to the sign at the entry of the HILLDALE neighborhood, the subtext reads "A Place For Success" but someone has vandalized the sign to read "A Place For Suckers" (The letters "CK" are spray painted on) The vandalism is a subtle suggestion that Hilldale, a seemingly middle class neighborhood, is not a good area. This is a payoff to the repeated lines by the police officers who take Jennifer home. Twice they complain about how bad the neighborhood is and the kinds of people who live there.
  • In alternate 1985, Doc reveals that alternate 1985 Doc was committed to a mental institution. Christopher Lloyd appeared in One Flew Over the Cuckoo's Nest (1975), where he played a patient in a mental institution.
  • This film introduces a new character trait for Marty: losing his temper (and self control) when someone calls him a "chicken." Robert Zemeckis and Bob Gale added this idea because they felt Marty did not have any character flaws in the first film.
  • According to the book "We Don't Need Roads - the Making of the Back to the Future Trilogy" by Caseen Gaines, the original plan for Marty's hoverboard was to have the name of Swiss watch company Swatch on it, (implying the company branched out into other products by 2015) before a deal was struck with Mattel.
  • Darlene Vogel wore a red contact lens in her right eye as Griff's female gang member Spike. According to her, this idea developed because her own eye has two different colors in it. This is a condition called Heterochromia iridum. Wesley Snipes has the same thing.
  • The movie's prediction of a Major League Baseball team in Miami was not as far off or far fetched as it may appear. At the time of the movie, Miami was known to be actively seeking a Major League Baseball team. It was less than two years after the film's release when the city was awarded with an expansion team the Florida (later Miami) Marlins who began play in 1993. During the 2015 season, the Marlins used some promotional themes and giveaways relating to the fictional Miami team portrayed in the movie. This included T-Shirts with the fictional team's logo noting them as 2015 American League Champions. On one occasion the Marlins mascot Billy Marlin was altered to fit the Back To The Future themed promotions and was temporarily renamed Billy McFly. In addition, one of the promotional events was held during a Marlins series in which they played the Cubs, the fictional winners of the 2015 World Series as seen in the film.
  • A VHS tape of National Lampoon's Animal House (1978) is visible in the antique store in 2015. John Belushi, Tim Matheson and Animal House director John Landis had all appeared in 1941 (1979), which Robert Zemeckis and Bob Gale co-wrote and Steven Spielberg directed. Spielberg also had a brief relationship with John Landis. Landis would give Spielberg a cameo in The Blues Brothers (1980). Landis also included a poster of the Spielberg directed movie Close Encounters of the Third Kind (1977) in An American Werewolf in London (1981) in the scene where the werewolf chases the man in the subway. However, after what happened with Landis on Twilight Zone: The Movie (1983), their friendship would end.
  • There's a popular film theory that Marty actually originally died in the tunnel when Biff was chasing him down. Originally, Marty was run down by Biff in Biff's '46 Ford. Doc found Marty, then decided to travel a few minutes into the past. That is how Doc knew to be at the end of the tunnel with the "rope" to save Marty.
  • They were one year off on the Cubs winning the World Series.
  • Miami becoming an American League franchise in 2015 was not far off, as the Marlins were one of two National League franchises considered to switch leagues for the 2013 season. The Major League Baseball Board of Governors voted to move the Houston Astros from the National League Central to the American League West that season.
  • In an interview, years after working on this film, Flea (Needles) called this movie "a multi-million dollar piece of trash".
  • The only film in the franchise where the future (2015) is visited.
  • The Wild Gunman (1984) video game that Marty plays at the Café'80s when he talks to the two boys is a strong foreshadowing of Back of the Future Part III (1990), in which Marty travels back through time to 1885 to rescue Doc, who is trapped in that time period.
  • In the film, Doc, Marty and Jennifer travel across time to 2015 and they travel back in time to alternate 1985. 2015 was the year Terminator Genisys (2015), the reboot of the classic time travel film The Terminator (1984) was released. In that film, Kyle Reese (Jai Courtney) travels back through time to 1984 and travels forward across time with Sarah Connor (Emilia Clarke) to alternate 2017.
  • Terminator Genisys (2015) the reboot of The Terminator (1984), which is a classic time travel film starring Arnold Schwarzenegger as a time travelling cyborg assassin, was released in 2015, which is the year, to which Doc, Marty, and Jennifer travel forward across time.
  • Marty and Marty, Jr. both wear a multicolored cap. A plausible nod to the long-running British science fiction series Doctor Who (1963). In that series, the 6th incarnation of the show's title character The Doctor (Colin Baker) an extra-terrestrial time traveller wore a multicolored jacket. Doctor Who (1963) was cancelled the same year as this film's release.
  • At the Café '80s, Marty orders a Pepsi. Michael J. Fox had appeared in Pepsi advertisements in the 1980s.
  • In the first film, it was established Marty is seventeen in 1985. In 2015, Marty is forty-seven.
  • Claudia Wells was unable to return as Jennifer Parker, due to her mother's ill health, and Elisabeth Shue assumed the role.
  • The song that is heard at the Café '80s is "Beat It" by Michael Jackson.
  • Instead of using footage of the previous film's closing scene for the opening scene of this film, it was decided that the closing scene of Back to the Future (1985) was to be re-shot, due to the re-casting of Jennifer.
  • In real-life 2015, the Pepsi Company decided to celebrate the Back to the Future trilogy's 30th anniversary by manufacturing and releasing 6,500 replicas of the 2015 Pepsi bottle from this movie, for the price of $20.15, as a Limited Special Edition.
  • It took eleven months for this movie and Back to the Future Part III (1990) to be filmed back-to-back.
  • The main thing that the science fiction genre has taught us about time travel is about it's consequences: Elderly Biff steals the time machine and gives the almanac to his younger self to profit and get rich resulting in the creation of an alternate 1985 which Biff is greedy, evil, and corrupt, and rules a chaotic dystopic society.
  • 1985-A is the only timeline in the whole trilogy that you never get to see during daylight. In other words, it is the only one to which Doc and Marty travel where it is night time during the whole time they're in it.
  • Director Robert Zemeckis stated that the high school dance scene from 1955 had to have the same costumes because it would be shot from a different angle. The production was nearly delayed because Lorraine's (Lea Thompson) dress couldn't be found even though they had three versions of it made in 1985. Lea Thompson then revealed to Zemeckis that she still had one of the original dresses and had to drive back home to get it.
  • The reason for Marty McFly Jr's arrest was because of stealing an unsubstantiated amount of money from the Hill Valley Payroll SubStation.
  • The leader of the band at the Enchantment Under the Sea dance is Marvin B-E-R-R-Y, and his band "The Starlighters" not "BARRY" as mentioned in other comments. Marvin BERRY steps off stage to call his cousin CHUCK BERRY not "BARRY" as erroneously mentioned in other comments!
  • When Marty, Jr. (in 2015) leaves the Café '80s and almost gets hit by a car while crossing the street, the timing is virtually identical to Marty doing the same thing while escaping Biff (in 1955).
  • When Marty, Jr. almost gets hit by a car while crossing the street, he swipes at the car's hood and shouts "Hey I'm walking here! I'm walking here!" This is an exact re-creation of Dustin Hoffman's famous ad-libbed line as Ratso Rizzo in Midnight Cowboy (1969).
  • Christopher Lloyd and Elisabeth Shue appeared in Back to the Future Part III (1990), Twenty Bucks (1993), and Piranha 3D (2010).
  • Christopher Lloyd and Lea Thompson appeared in The Right to Remain Silent (1996).
  • Michael J. Fox and Christopher Lloyd appeared on Spin City (1996) and The Michael J. Fox Show (2013).
  • Christopher Lloyd and Elijah Wood appeared in Over the Garden Wall (2014).
  • At the beginning of the movie, Doc assures Marty, "you and Jennifer turn out fine". Marty and Jennifer were far from fine: Marty lost everything and married Jennifer in Vegas, and even Biff comments to Marty (thinking that he is Marty Jr.) that Marty Sr. "flushed his life down the toilet".
  • According to the video Marty watches at the Biff Tannen Museum, in the alternate timeline in which Biff was rich and powerful, his first two wives were Marilyn Monroe and Jayne Mansfield.
  • The Tannen family seems to skip a generation: Biff has a grandson named Griff, but Biff's children/Griff's parents are never seen or even mentioned. Biff lives with his grandmother in 1955 but his parents are never seen or mentioned.
  • On October 21, 2015, fans gathered in the parking lot of the Puente Hills Mall, City of Industry CA, site of the fictitious Twin Pines/ Lone Pine Mall. Many fans hoped for a real time machine to appear. Others celebrated the day by watching BTTF on a giant screen.
  • Old Biff should have recognized Marty as Calvin Klein when he meets him in the 80's cafe.
  • Elizabeth Shue said this was her favorite project in People interview.
  • Doc would have noticed Old Biffs cane in the car when he traveled back to 1985 with Marty.
  • Marty said Old Biff stole his idea with gambling from the sports almanac. Actually, this was the man who was raising money to save the clock tower's idea when he said he wished he knew the Cubs won so he could go back and bet on them when they were 100 to 1 shot. This is where Marty got the idea and bought the almanac.
  • Robert Zumekis and Charles Fleischer worked on the roger rabbit before this film. Charles Fleischer appears twice in This film. First, in the future, as someone collecting donations for the clock tower. He is then seen again in 1955 as a mechanic for the garage that fixes Biff's car after the famous manure scene.
  • As of 2018, the original self-lacing Nikes used in the movie are disintegrating.
  • All the cars in the film were recycled from other movies set in the future.
  • The opening shot of the DeLorean flying through the clouds was footage originally shot for the Clint Eastwood action film Firefox (1982).
  • One of the inspirations between filming the second and third instalments back-to-back was that Richard Lester had done it before with The Three Musketeers (1973) and The Four Musketeers: Milady's Revenge (1974).
  • Make-up problems were encountered when old-age Biff is caught by Marty in a hot tub. The heat from the tub would make Thomas F. Wilson's make-up start to melt.
  • Robert Zemeckis was very unhappy about the way that Universal marketed the film. He wanted it to be made quite clear that this film was ultimately a set-up to Back to the Future Part III (1990) but Universal wanted to advertise it as its own independent movie. This ultimately backfired as Back to the Future Part II (1989) ends with a 'To Be Concluded" title that frustrated many audiences, resulting in bad word of mouth and a dramatic fall-off in the film's box office receipts in its second week.
  • In one scene, Doc Brown rides a bicycle (very badly). In reality, Christopher Lloyd is a keen cross-country cyclist.
  • This film has three different DeLorean time machines co-existing on November 12, 1955: the one that Marty used in the first film, the one that Biff used to travel from October 21, 2015 and the one that Marty and Doc used to travel from October 27, 1985 in the alternate timeline.
  • Michael J. Fox's performance as Marlene McFly was dubbed by Grey Griffin.
  • The film takes place on October 26, 1985, on October 21, 2015, from October 26 to October 27, 1985 in the alternate timeline and on November 12, 1955.
  • The photograph of the woman on the cover of the French magazine "Oh LàLà" is a flipped shot of Venetia Stevenson taken from the cover of the July 1955 issue of "Swank".
  • In 2015, there are several items in both the Café 80s and Blast from the Past which would have been familiar to the audience in 1989 but not to Marty, being from 1985. In the Café 80s, The Oprah Winfrey Show (1986), Pee-wee's Playhouse (1986), The Geraldo Rivera Show (1987) and Dead Ringers (1988) are among the series and films playing on the many televisions behind the bar. There is also a poster celebrating the San Francisco 49ers' victory in Super Bowl XXIII on January 22, 1989. Furthermore, the Ollie North Platter offered on the menu and a bumper sticker on the wall reading "For the first time in history, the South loves North" both reference the 1988/1989 trial of Colonel Oliver North for his role in the Iran-Contra affair.

  • Since no visible "ripple effect" changes seem to occur in the 2015 Hilldale's landscape just prior to and during the moments when Biff clumsily returns with the DeLorean after his selfishly-destructive trip back to 1955, it is implied that the timeline remains pretty much the same --- at least in Hilldale, where Doc and Marty are --- in the "late date" of 2015 as it would have been "originally", even after Biff had begun horribly altering it sixty years prior. This indicates that --- perhaps largely due to Lorraine's having murdered the abusive Biff sometime in the mid-to-late-'80's, and thus ended his impetuous reign of consumptive "terror 'n' tyranny" some 25 years earlier --- the timeline in the Hill Valley area may have had a chance to largely "recover" in the ensuing two-plus decades, in that the Hill Valley residents had managed to mostly "clean up and correct" Biff's "urban decay" damage by the time 2015 had rolled around. One wonders how this "gradual return to normal" could have been possible, however, since it is clearly shown that the destructive "fallout" of Biff's evil actions had not been limited to just his own local stompin' grounds --- the ENTIRE WORLD had apparently been drastically altered (i.e., "Nixon to seek fifth term", "President vows that Vietnam War will end within the year", etc.), with said desecration apparently having been mostly due to Biff's "filthy-rich guy" interferences. So even with Biff himself no longer in the picture, it seems highly unlikely that the widespread desecration he'd caused would have been able to get magically erased in less than thirty years. Also, how can we be sure that Biff's "early and initial" changes to his surroundings (i.e., the corruption and chaos that he'd begun creating shortly after winning his first million dollars at the '58 horse-race on his 21st birthday) might not have been somewhat "self-defeating" to his future aspirations of acquiring even more wealth and power by betting on sporting-events? If we are to believe that any significant altering of the space-time continuum can have drastic effects on the universe in general, then it naturally follows that Biff's negative-natured interfering with the timeline on a "global" or "worldwide" scale would likely have altered the outcomes of future sporting-events, as well (assuming, of course, that the resulting strife-and-corruption-torn world would have even still possessed the time, public interest, and/or wherewithal to be able to actually HOLD said sporting events in the first place, rather than the masses' having to concentrate all their energy and resources merely on their struggle to survive), since now there would probably have been drastic changes in the events' competitors and their training/capabilities, greatly altering the outcomes of the sporting events and thus largely rendering useless Biff's precious sports almanac, since the "original" or "normal" timeline from which the book's written statistics came from had now been altered. This is something that's always bugged me about this otherwise-wonderful movie... how could Biff have kept winning his almanac-determined bets at sporting-events, when the entire world --- and presumably the identities/capabilities/performances of its sports-contenders, as well --- had been so drastically altered.
  • The Tannen family seems to skip a generation, Biff's grandmother is at least mentioned (heard but not seen), his great grandfather is Buford "Mad Dog", and his grandson Griff. But no mention of biff's parents or children. And although Griff is played by the same actor as Mad Dog & Biff (the latter in both 1955 & 1985A), Griff & Mad Dog's gangs are comprised of different actors.
  • When Marty arrives in downtown Hill Valley in 1985A he steps on a Hill Valley sign. The "il" was spray painted over with "E" to make it read, "Hell Valley. Marty later says to Doc, "It's like we're in hell".
  • Goldie Wilson III is the mayor of Hill Valley. Biff is played by Thomas F. Wilson; the same last name.
  • Marty McFly's house was filmed only ¼ mile (½ Km) from a scene in Caesar and Otto's Paranormal Halloween (2015).
  • Contrary to popular belief, there are more than two versions of 1985; there are three: * The original at the beginning of part 1: Dave mcFly works at Burger King, Lorraine is an alcoholic and lectures Marty about girls who chase boys, Biff is George's boss. * The End of Part 1, after George punched out Biff, which resulted in George being a successful author and owns a BMW and Biff is not his boss but rather, is his subordinate (ie. he details George's BMW). * Then there's the 1985A that everyone knows about: Biff is wealthy, powerful, & evil, and he and murdered George McFly.
  • The reason for Marty McFly Jrs. arrest was because he was caught stealing an unsubstantiated amount of money from the Hill Valley Payroll Substation.
  • A deleted scene involving Wendie Jo Sperber appearing as a hooker was canceled due to her being pregnant at the time. As she could not appear, it was also decided that an adjacent scene with brother Dave McFly as a drunk would not be included because fans would wonder what happened to her.
  • [46:04]When Match says, "we can do this the hard way or the easy way" then hits him on the head. The screen goes black and you hear a deep voice with an echo say, "the easy way". This is presumably Marty saying it because if you use a sound editor to raise the pitch by 25%, it sounds just like Michael J. Fox.
  • During the early stages of production, Crispin Glover was coming around to the idea appearing in the film. Bob Gale tried to sweeten the deal by offering him double what he made from the first film and also offered him the role of Seamus McFly in Back to the Future Part III. However Glover responded by hiring new agents and who demanded more money.
  • In the film in 2015, When Doc arrives with the flying Delorean, Old Biff says to himself "Flying Delorean? I haven't seen one of those in 30 years". Actually until the end of the film Biff had the chance to see 3 times a flying Delorean during the course of his life : in this scene in 2015 , in the beginning of the movie when Marty, Doc and Jennifer go into the future in 1985, and finally at the end of the film in 1955 after Marty is rescued by Doc in the flying Deloran after the chase in the tunnel.
  • In observance of the 30th anniversary of the original film a Deloran user group held a raffle for a restored Delorean. The raffle fee was $50. Many people were skeptical of the online purchase and avoided it. As a result, there were only some 850 entries. As a result, the group only received about $42,500, which barely paid for the cost of the car and renovation.
  • The opening titles featured visuals of flying through clouds. The sequence begins in the daytime and ends with flying through dark, stormy clouds. This foreshadows the trip to the future during which they depart in the bright sunshine and arrive in the future in extremely dark weather. Incidentally, when they land, it is raining but clears up instantly, thanks to weather control.
  • Many viewers did not make out what the two Jennifers are screaming when they faint. 2015 Jennifer screams, "I'm young!" and 1985 Jennifer screams, "I'm old!"
  • Doc postulates that there must be some unfathomable significance to the date November 12, 1955 for this to be the date selected by Biff. It is significant, because that was the date that he was knocked out by George McFly and which was the start of when he became a loser.

Spoilers

  • According to the revised six dollar USA Today newspaper article (which formerly featured Marty McFly, Jr. arrested for theft, and now featured Griff Tannen's gang arrested for destruction of the Hill Valley courthouse's window), the real names of Griff's 2015 gang, Data, Spike, and Whitey, are Rafe Unger, Leslie O'Malley, and Chester Nogura.
  • When the producers knew they were going to make a sequel they tried to get as much of the original cast back together. The only actor who did not agree right away was Crispin Glover, who disputed his salary, and so the character of George McFly was written out (murdered in the alternate future).
  • This is the only film in the trilogy that does not end with a time travel vehicle flying directly at the camera.
  • In early scripting, the DeLorean's malfunctioning time circuits were due to a police shoot-out's or Old Man Peabody's having damaged the car from gunfire. These scenes were later rejected, and so the time display's flickering was impliedly attributed to merely the amateur "prototypical" construction of the time machine (Doc had been the first one to successfully create time travel, after all, and so his initial invention, the somewhat cobbled-together sports-car rig, rather than the subsequently-constructed and more-professionally-designed steam-locomotive machine, would understandably be fairly primitive and experimental, and thus more prone to malfunctions), and to all the stress and battering about that it endured (especially during the periods with the inexperienced Marty, and the clumsy or infirm Biff at the controls) during its life up to that time.
  • In this movie, Marty, Doc, and Jennifer travel to October 21, 2015. While there Marty sees a news story showing the Cubs winning the World Series in a sweep against Miami. In 2015, the Chicago Cubs did make their first playoff appearance since 2008 and made it to the NLCS (by defeating the Pittsburgh Pirates and St. Louis Cardinals). However, on October 21, 2015, the Cubs were swept by the New York Mets.
  • In the alternate timeline, George McFly was murdered by Biff Tannen on March 15, 1973. March 15 is the Ides of March. In 44 BC, this date became notorious as the date of the assassination of Julius Caesar which made the Ides of March a major turning point in Roman history.
