  • The synthesizer that President Hathaway (Stephen Colbert) uses to communicate with the giant robot is a Yamaha DX7.
  • WILHELM SCREAM: When B.O.B. (Seth Rogen) throws the last Gallaxhar clone to the floor far down below when he meets up with the other main monsters during the spacecraft invasion.
  • In the scene during the closing credits, President Hathaway asks the audience if anyone wants to freeze his head. Stephen Colbert, who provided the voice of President Hathaway, gives detailed outlines on how to unfreeze his head in an apocalyptic future in his book, "I Am America and So Can You".
  • The fighter jets are F-14 Tomcats and the helicopters are AH-64 Apaches.
  • While President Hathaway resembles Stephen Colbert, the character's look had been finalized some time before Colbert had been cast for the part.
  • The large aircraft used to transport the monsters to San Francisco is based on an actual Guppy aircraft. The first Guppy was built in 1962 for N.A.S.A. by Aero Spacelines of California to transport spacecraft components.
  • The first computer-animated movie directly produced in a stereoscopic 3-D format, instead of being converted into 3-D after completion.
  • A code title used during production was "Showdown".
  • The multi-colored pads on which Dr. Cockroach Ph.D. (Hugh Laurie) dances use the same sound effects as the light-up memorization game "Simon". The dancing in sync with the lighted pads is a reference to the arcade game Dance Dance Revolution (1998), in which you do the same thing, only in sync with the on-screen prompts.
  • The San Francisco streetcar that Dr. Cockroach, Ph.D. modifies with rocket engines is an Italian-made vintage Peter Witt streetcar in the 1928 white-and-yellow color scheme. The streetcar in the movie has number #2930 (as of release, not an assigned number).
  • This movie was set in Modesto, California, the birthplace of George Lucas.
  • For the scenes of Ginormica wandering the streets of San Francisco, a replica of the set was built, and supervising animator Line Korsgaard Andersen was videotaped walking around it as reference for the animators.
  • The two technicians who first discover Gallaxhar's ship are named Ben and Jerry, like the ice cream brand.
  • In one of the cities where Gallaxhar's message is being shown, there are blinking neon letters on one of the skyscrapers. These letters are Japanese katakana, and they spell "ka-ra-o-ke".
  • The license plate of the yellow cars Susan uses as a roller skate reads "XQZMEEEE" or "excuse me", which she later says as she is skating through traffic on her way to the Golden Gate Bridge.
  • After Susan saves B.O.B., Link, and Dr. Cockroach from being crushed on Gallaxhar's ship, after becoming Ginormica again, Dr. Cockroach says "By Hawking's chair." This is a reference to Stephen Hawking, a renowned academic who was bound to a motorized wheelchair due to amyotrophic lateral sclerosis, also known as A.LS. or Lou Gehrig's disease.
  • The famous sound effect, the "Wilhelm Scream", was featured in this movie. The scream was originally done in the 1950s by Sheb Wooley, who sung Flying Purple People Eater (1958), which was used in the closing credits.
  • The two technicians who first discover the incoming meteor call the control center and issue a "Code Nimoy" alert, an homage to Leonard Nimoy.
  • When Gallaxhar says "UUUH! Fire phasoid cannon!" you can see the contrail left behind by the flying tennis rackets going past his eyes. The filmmakers also confirmed that.
  • The screen on the machine, that Dr. Cockroach, Ph.D. (Hugh Laurie) uses to try to get Susan (Reese Witherspoon) back to normal size, shows the two pictures of Susan in 8-bit form, which was the style used a lot in arcade games.
  • This movie has a localized version in Australia, where the News Reporter was not voiced by Ed Helms, but instead voiced by David Koch, a co-presenter of the morning show "Sunrise", seen on Channel 7 across Australia.
  • When Gallaxhar (Rainn Wilson) is talking to Earth about what he is about to do, in the scene when Gallaxhar is talking in Tokyo, Japan, on the top left corner, a scene from Madagascar (2005) can be seen of Marty talking to Alex.
  • President Hathaway's code name is "Papa Bear", which is what Stephen Colbert called Bill O'Reilly on The Colbert Report (2005).
  • The monsters shown in the movie are all references to original monsters in movies. Ginormica (Reese Witherspoon) is a reference to Attack of the 50 Foot Woman (1958), B.O.B. (Seth Rogen) is a reference to The Blob (1958), The Missing Link (Will Arnett) is a reference to Creature from the Black Lagoon (1954), Dr. Cockroach Ph.D. (Hugh Laurie) is a reference to The Fly (1958), and finally Insectosaurus is a reference to Mothra from Mosura (1961).
  • Each Monster on the team is virtually immortal.
  • The first full length trailer for this movie appeared during Super Bowl XLIII in 3-D. Prior to the game, various displays were set up throughout the U.S., giving away free 3-D glasses.
  • Rainn Wilson, John Krasinski, Ed Helms, and Will Arnett appeared on The Office (2005).
  • Early in the movie, B.O.B is bouncing a ball off the wall of his cell. This could be a reference to Hilts, the Cooler King (Steve McQueen) from The Great Escape (1963). McQueen played Steve Andrews in The Blob (1958) (B.O.B is a parody of the Blob).
  • The song that President Hathaway (Stephen Colbert) plays on the synthesizer is "Axel F" by Harold Faltermeyer, which was featured in Beverly Hills Cop (1984) and Beverly Hills Cop II (1987).
  • Final DreamWorks Animation movie to have the 2004-styled DreamWorks Animation SKG logo, where the fisher boy uses balloons to get up to the moon.
  • LOGO GIMMICK: The "DreamWorks Animation SKG" logo is in black-and-white, and the fisher boy gets sucked up by a U.F.O., and the screen vibrates after that, and the screen rips off to the galaxy.
  • Seth Rogen's third DreamWorks Animation movie, after Shrek the Third (2007) and Kung Fu Panda (2008).
  • After Insectasaurus becomes a butterfly, and is getting ready to fly to Paris, she is wearing lipstick, indicating that she is female.
  • General W.R. Monger's (Kiefer Sutherland's) insignia, on his right chest, is a combination of clouds and the title character of Shrek (2001)'s face, a nod to another DreamWorks Animation "monster".
  • In just the beginning, the tech guy says "Supernova, this is Red Dwarf". Red Dwarf (1988) is a British comedy of science fiction set in space. Supernova and Red Dwarf are also stages in the life of a star.
  • Insectosaurus is a combination of Godzilla, Mothra (of Godzilla's movies fame) and the Tyrannosaurus Rex from the Jurassic Park film franchise.
  • President Hathaway playing the five-note tune on the keyboard, before he plays "Axel F", was from Close Encounters of the Third Kind (1977).
  • This is the second DreamWorks Animation movie to have a female protagonist, after Chicken Run (2000).
  • Kiefer Sutherland and Reese Witherspoon appeared in Freeway (1996).
  • DreamWorks Animation's eighteenth feature film, and last movie of the 2000s.
  • Hugh Laurie's second DreamWorks Animation movie, after the fan-made The Sky-High City of Steampuff (2006).
  • The large room, in which members of the U.S. Government meet up to use monsters as a form of defense against the aliens bears a striking resemblance to the war room from Dr. Strangelove or: How I Learned to Stop Worrying and Love the Bomb (1964). The character of General W.R. Monger even resembles and sounds like General Turgidson (George C. Scott) from that Stanley Kubrick movie.
  • When the Monsters are fighting the alien robot on the Golden Gate bridge, it shows a solid middle divider between north and south lanes. The bridge actually uses yellow removable pylons, so the amount of lanes on a given side can be adjusted for commute hours.
  • The city of Modesto, California was depicted as a small, rural farm town in this movie, when in reality, it is a bustling city, right off the California 99 freeway that flows through the city.
  • Seth Rogen, Will Arnett, and Amy Poehler's second animated movie together, after Horton Hears a Who! (2008).
  • Susan resembles her voice actress Reese Witherspoon (at least after she becomes Ginormica, and her hair changes to white).
  • One of the missiles fired from the Apache helicopters at the alien robot says "E.T. Go Home!" and when it's seen on-screen, the iconic theme to E.T. the Extra-Terrestrial (1982) can be heard.
  • "Planet Claire" from The B-52's is playing as President Hathaway climbs the stairs before addressing the alien robot.
  • Renée Zellweger's third DreamWorks Animation movie, after Shark Tale (2004) and Bee Movie (2007). All those times had her voicing a love interest, but instead of being one to the main character, she voices the lady of the couple that first encounter Galaxhar's giant robot once it arrives on Earth.
  • DreamWorks Animation's second biggest opening for a non-sequel, opening to $59,300,000. It's only behind Kung Fu Panda (2008), which opened to $60,200,000.
  • After being nominated without winning ten times in the past, DreamWorks Animation finally won their first Saturn Award for Best Animated Film with this one. They'd get nominated seven more times in the future, but only one of those seven nominations, Puss in Boots (2011), won.
  • Seth Rogen's (B.O.B.'s) second collaboration with Amy Poehler and John Krasinski, after Shrek the Third (2007), also from DreamWorks Animation.
  • With a budget of $175 million, this is the most expensive animated movie not produced by Disney/Pixar.
  • Before turning into Ginormica, Susan Murphy (Reese Witherspoon) has brown hair. This makes it the second time Witherspoon played a brunette. The first being Walk the Line (2005).
  • The third-highest grossing animated movie of 2009, after Ice Age: Dawn of the Dinosaurs (2009) and Up (2009).
  • Though some say this movie barely made back its $175 million budget, its final worldwide gross was $381,509,870, more than twice the amount.
  • Reese Witherspoon has denied appearing in any further sequels beyond her first sequel Legally Blonde 2 (2003), after having had an unpleasant time being a part of it. That was the only sequel movie she appeared in up until Sing 2 (2021), which is a likely reason as to why this movie never became a franchise.
  • Third theatrically released animated movie for Kiefer Sutherland, after The Nutcracker Prince (1990) and The Wild (2006).
  • The first DreamWorks Animation movie composed by Henry Jackman, who also composed Puss in Boots (2011) and Turbo (2013).
  • Amy Poehler and Will Arnett were a real-life married couple at the time of this movie's release, and voiced enemies to each other in this movie. They also appeared together in fellow animated movie, Horton Hears a Who! (2008), but through the opposite sorts of roles that they have in this movie.
  • This is the third DreamWorks Animation movie released in a 2:35:1 aspect ratio, after Spirit: Stallion of the Cimarron (2002) and Kung Fu Panda (2008) both of which jointly had Hans Zimmer and John Powell compose the score.
  • Throughout the scene where Susan turned into Ginormica, and the rest of the movie, no one points out that her hair turned white.
  • Seth Rogen's fourth animated movie after Shrek the Third (2007), Horton Hears a Who! (2008), and Kung Fu Panda (2008).
  • Will Arnett's fourth animated movie after Ice Age: The Meltdown (2006), Ratatouille (2007), and Horton Hears a Who! (2008).
  • This is the ninth movie in which the Golden Gate Bridge has been destroyed, after It Came from Beneath the Sea (1955), Invasion of the Body Snatchers (1978), Superman (1978), A View to a Kill (1986), The Rock (1996), The Core (2003), X-Men: The Last Stand (2006), and Mega Shark vs. Giant Octopus (2009).
  • Susan is exactly forty-nine feet eleven inches (15.21 meters) tall, making her almost the same height with Nancy Archer from Attack of the 50 Foot Woman (1958). The creators did this so that people won't get confused.
  • Dr. Cockroach, Ph.D. is the smartest monster in the group, and second being Susan Murphy/Ginormica.
  • The scene with the three monsters looking down at the marching clones while plotting to save Susan is similar to the scene from The Wizard of Oz (1939), where Scarecrow, Cowardly Lion, and Tin Man are looking down on the wicked witch's soldiers. The dumb member of each group (Scarecrow and B.O.B. respectively) comes up with the same plan: disguising themselves to blend in.
  • The hand sign that President Hathaway does when meeting the Robot Probe is the Vulcan peace sign from Star Trek (1966).
  • As President Hathaway is walking up the platform to communicate with the robot probe, one of the Secret Service Agents references him as code name: "Papa Bear". Stephen Colbert called his "idol" Bill O'Reilly "Papa Bear" on The Colbert Report (2005).
  • In earlier drafts of this movie, Susan was supposed to be called the "50,000 pound woman".
  • In this movie, old footage of Insectosaurus shows her attacking Tokyo. This is similar to what Godzilla did in Godzilla (1954).
  • Even though this movie doesn't have a sequel yet, it is still a franchise. It has one video game, one short film: B.O.B.'s Big Break (2009), two television specials: Monsters vs. Aliens: Mutant Pumpkins from Outer Space (2009) and Night of the Living Carrots (2011), and one television series with the same name which aired from 2013 until 2014.
  • The song to which Dr. Cockroach, Ph.D. dances in Gallaxhar's ship is "Roses Are Red" by Aqua.
  • Susan is the strongest monster in the group, as she is seen holding off the Robot Probe's giant hand, and singlehandedly pulling down the Robot with the cables of the Golden Gate Bridge.
  • In the beginning, Susan wakes up and gets scared in the same way a child gets frightened by a monster in Disney/Pixar's Monsters, Inc. (2001).
  • Susan's (Ginormica's) space suit in this movie resembles Jennifer Lopez's red bodysuit in The Cell (2000).
  • The Invisible Man is dead in this movie, but he appeared in the short film, B.O.B.'s Big Break (2009), as that story took place before this movie.
  • This movie takes place over the course of three weeks. When Susan Murphy (Reese Witherspoon) reunites with Derek Dietl (Paul Rudd), she says "You wouldn't believe my last three weeks."
  • The base in which the monsters stay hasn't had its name revealed yet, or sometimes called "Area Fifty-Something". In the large situation room, an advisor was shot with a sedative to stop him from mentioning the name.
  • Susan falls down five times in this movie: First, at her wedding when she gets shot with the sedative. Second, when she turns to the right side of her bed, thinking there was an alarm clock. Third, when she steps on B.O.B. Fourth, when she starts to run away from the Robot Probe. Fifth, when she trips over a car.
  • When Susan is being chased around San Francisco by the Robot Probe, she accidentally slips off a roof and hangs on to the rain gutter. This is a reference to the opening scene of Vertigo (1958).
  • Dr. Cockroach, Ph.D. (Hugh Laurie) completing the color code system to initiate self destruction mode is similar to the way David Levinson (Jeff Goldblum) uploaded a computer virus into the Mothership in Independence Day (1996).
  • When the military shoots missiles to the Robot Probe, the missiles get deflected. This is similar to War of the Worlds (2005) and Independence Day (1996), where the military shoots missiles but they get deflected by the aliens' shields.
  • Susan is able to survive extremely heavy and atomic forces, making her virtually indestructible. This is because of her power, which comes from the "quantonium" substance.
  • At one point, Dr. Cockroach, Ph.D. asks Susan Murphy/Ginormica if she has any "uranium" in her. Uranium is radioactive material used in the construction of and to power up nuclear power plants, nuclear missiles, and atomic bombs.
  • Gallaxhar (Rainn Wilson) says "Extract the Quantonium with extreme prejudice", a reference to the quote "Terminate with extreme prejudice" from Apocalypse Now (1979).
  • The scene where The Missing Link is found frozen in an iceberg but thaws and escapes is similar to the discovery of the creature found frozen in The Thing (1982).
  • Music from Clash of the Titans (1981) can be heard when Susan pulls the cables of the Golden Gate Bridge.
  • When Susan chases Gallaxhar through the ship, doors start to close as she runs and breaks through them, a reference to Alien (1979).
  • This movie and Megamind (2010) have many similarities. First, they are parodies of other pop culture icons: this movie was inspired by monsters from the 1950s and 1960s, while Megamind was inspired by superheroes and villains like Superman, Batman, and Lex Luthor. Second, they talk about empowerment: Susan feels proud to be a monster, while Megamind accepts his role as a hero. Third, they both have aliens: this movie has Gallaxhar, and Megamind has the title character. And fourth, they both grossed over $300 million in the worldwide box office: this movie earned $381 million, while Megamind earned $321 million.
  • When Insectosaurus looks at bright lights, her pupils get smaller and they follow the direction of that light, similar to how the Tyrannosaurus Rex followed the flares held by Dr. Alan Grant and Ian Malcolm in Jurassic Park (1993).
  • Susan Murphy/Ginormica used cars as skating shoes when escaping the Robot Probe. This was a reference to Transformers (2007), when Bonecrusher, a Decepticon who has wheels for feet, skates down the highway.
  • Insectosaurus is the only monster who can't speak. She only growls and roars.
  • When Susan grows into a giant, her wedding dress starts to tear, exposing bare arms and legs, making her resemble Nancy Archer in the poster of Attack of the 50 Foot Woman (1958).
  • The food served on Susan's table is oatmeal.
  • In the scene where Insectosaurus meets the Robot Probe in the Golden Gate Bridge, fans would make remarks to Pacific Rim (2013), a movie about man-made robots who fight giant monsters.
  • In the original concept arts of this movie, The Missing Link has more chest hair than what was displayed in this movie. The creators decided to reduce the amount of hair he has to make him look more like a "macho jock".
  • B.O.B. is colored blue, while his inspiration, The Blob monster from The Blob (1958), was colored red.
  • This movie has several plot points similar to Rise of the Guardians (2012). The protagonist becomes different through no means of his or her own and his or her hair turns white as a side effect. What caused them to be different was presumably painful. (Jack fell into an ice cold lake and Susan was hit by a meteorite containing quantonium). After becoming different, they have no means of communication with the outside world. (No one believes in Jack Frost and Susan is locked away in a top secret facility). They must fight alongside other different individuals to defeat a deranged antagonist that wants things to go his way (Gallaxhar and Pitch Black). It is implied that a member of the team dies, (Insectosaurus and Sand Man) but they come back in the end proven to be alive.
  • What makes Insectosaurus similar to Godzilla is its size and ability to shoot silk, but Godzilla shoots his "Atomic" Breath.
  • It was mentioned by General W.R. Monger that Insectosaurus is three hundred fifty feet (106.7 meters) tall, which makes him twenty feet taller than Godzilla from Godzilla: Final Wars (2004), who stands three hundred thirty feet (one hundred meters).
  • Insectosaurus is seven times as tall as Susan Murphy/Ginormica.
  • This movie started as an adaptation of a horror comic book, Rex Havoc, in which monster hunter Rex and his team of experts called "Ass-Kickers of the Fantastic" fight against ghouls, ghosts, and other creatures. The earliest development goes back to 2002, when DreamWorks first filed for a Rex Havoc trademark. In a plot synopsis revealed in 2005, Rex was to assemble a team of monsters, including Ick!, Dr. Cockroach, the 50,000 Pound Woman, and Insectosaurus, to fight aliens for disrupting cable television service. In the following years, the story diverged away from the original Rex Havoc, with Directors Conrad Vernon and Rob Letterman finally creating the storyline from scratch.
  • Ever since this movie was made, all feature films released by DreamWorks Animation were produced in a stereoscopic 3-D format, using Intel's InTru3D technology. IMAX 3D, RealD and 2-D versions were released as well.
  • To promote the 3-D technology that was used in this movie, DreamWorks ran a 3-D trailer before halftime in the U.S. broadcast of Super Bowl XLIII on February 1, 2009. Due to the limitations of current television technology, ColorCode 3-D glasses were distributed at SoBe stands at major national grocers. The Monsters, except Susan and Insectosaurus, also appeared in a 3-D SoBe commercial airing after the trailer.
  • In July 2014, the distribution rights were purchased by DreamWorks Animation from Paramount Pictures and transferred to Twentieth Century Fox. The rights are now owned by Universal Pictures.
  • In 2009, this movie was nominated for four Annie Awards, including Voice Acting in a Feature Production for Hugh Laurie. Reese Witherspoon and Seth Rogen were nominated for best voice actor and actress at the 2010 Kids' Choice Awards for voicing Susan and B.O.B, but lost to Jim Carrey for Disney's A Christmas Carol (2009). This movie was also nominated for Best Animated Film, but lost to Up (2009). On June 24, 2009, this movie won the Saturn Award for Best Animated Film.
  • In the "first look" photo of this movie's characters, Susan wears a red jumpsuit instead of the dark grey one shown in the movie. Although in the video game, she wears the red uniform when fighting the Robot Probe.
  • B.O.B. says "I haven't been outside for fifty years", this would mean that they have been in the base since 1958.
  • Years the monsters were captured: Susan/Ginormica: 2008, Dr. Cockroach, Ph.D.: 1961, B.O.B.: 1958, The Missing Link: 1962, and Insectosaurus: 1969.
  • The McDonald's Happy Meal toy figure of Susan showed her sporting blonde hair, and wearing a red jumpsuit with blue and green cars for her feet. This is an inaccurate representation of her compared to what was shown in the movie. She has platinum-white hair, wears a dark grey/orange jumpsuit, and is seen with red and yellow cars for her feet when skating.
  • Near the ending, although Link says "You're a butterfly!" to Insectosaurus (renamed Butterflyosaurus), she actually resembles a moth, which has feathery antennae, rather than a butterfly which has straight ones with knobbed ends.
  • Although Ginormica's prison uniform is numbered 00005, she clearly arrived after Dr. Cockroach, Ph.D., B.O.B., Link, Insectosaurus, and the Invisible Man (R.I.P.). This means that she should wear number 00006, but since Invisible Man is dead, it makes sense to let her wear 00005.
  • When Susan first transforms into Ginormica, her hair turns white as a side effect. However, when she gets back to her normal size by Gallaxhar, her hair remains white instead of being brown again. Some people pointed out that this is because of her stress levels, which causes her hair to permanently remain white.
  • The Robot Probe is somewhat similar to space probes sent by N.A.S.A. to discover Mars by snatching photos of the planet, while the Robot Probe instead monitors activity and destroys everything.
  • President Hathaway playing the synthesizer to communicate with the Robot Probe has become one of the most popular internet memes of the 2010s.
  • At one point, Gallaxhar curses "Oh Spaceballs!", a reference to the movie Spaceballs (1987).
  • Reese Witherspoon's first animated movie since The Trumpet of the Swan (2001). This is also her first 3-D animated movie from DreamWorks Animation.
  • The movie takes place in Modesto and San Francisco, California, and somewhere north of Las Vegas, Nevada (Area 5? base).
  • The ending of this movie could be forshadowing a sequel, but it was never made. Even though DreamWorks Animation could possibly helm the sequel, it would probably release sometime in the near future.
  • Goof, not a point of trivia. According to the Monsters vs. Aliens wikia page, the Robot Probe is three hundred sixty feet (one hundred nine meters) tall. Sometimes even regarded as "roughly the same size as Insectosaurus, but slightly taller". This is inaccurate compared to what was shown in the Golden Gate Bridge fight, as the Robot is clearly way taller than Insectosaurus (who is three hundred fifty feet). From what was displayed in the movie, the Robot could be anywhere around three hundred ninety to four hundred feet.
  • B.O.B. (Seth Rogen) was originally called "Ick!" in earlier drafts of this movie's production.
  • Production designer David James stated that this movie was "a return to what made us nerds in the first place", getting classic movie monsters and relaunching them in a contemporary setting. Director Conrad Vernon added that he found it would be a great idea to take hideous monsters and giving them personalities and satirizing the archetypes.
  • Ed Leonard, C.T.O. of DreamWorks Animation, said it took approximately forty-five million six hundred thousand computing hours to make this movie, more than eight times as many as Shrek (2001).
  • Several hundred Hewlett-Packard xw8600 workstations were used, along with a "render farm" of HP ProLiant blade servers with over nine thousand server processor cores, to process the animation sequences. Animators used one hundred twenty terabytes of data to complete this movie. They even used six terabytes for an explosion scene.
  • Based on 213 reviews collected by Rotten Tomatoes, this movie has an overall approval rating from critics of 72% and an average score of 6.5 out of 10. The website's critical consensus reads: "Though it doesn't approach the depth of the best animated films, Monsters vs. Aliens has enough humor and special effects to entertain moviegoers of all ages."
  • Director Conrad Vernon provided creature vocal effects for Insectosaurus.
  • The movie actually made back its $175 million budget by earning a total of $381 million worldwide, which is more than twice the amount, and enough to produce a sequel.
  • Many fans have been demanding a sequel for the past decade. Ever since DreamWorks Animation was bought by Comcast in 2016, the company has been restructuring the movies' slates throughout the years. Some sequels were either cancelled, pushed, or put on a temporary hiatus (for example Madagascar 4, Shrek 5). The Croods 2 (2020) for example, was cancelled on November 2016, but a year later, DreamWorks put it back on production with a new 2020 release date. Disney/Pixar's Incredibles 2 (2018) was released fourteen years after its predecessor. This means that there might be a chance that this movie will get a sequel in the future.
  • B.O.B. appeared in the video game, DreamWorks Super Star Kartz (2011), as a playable character and was voiced by Dave B. Mitchell.
  • There are a few scenes that were not featured in this movie, but were storyboarded as deleted scenes on the DVD releases. Some of these scenes include: Dr. Cockroach, Ph.D., The Missing Link, B.O.B., and General W.R. Monger plotting to fight off Gallaxhar's clones to reach a Robot Probe to fly it back to Gallaxhar's ship and rescue Susan. Another scene is in the Situation Room where President Hathaway and his advisors call General W.R. Monger and convince him to return the monsters to the base due to the trail of destruction left in San Francisco.
  • B.O.B. has 12,000 bubbles inside of him.
  • Hugh Laurie was chosen as the voice for Dr. Cockroach, Ph.D. when Dave Burgess animated a test of him accepting his Emmy award.
  • Originally, Gallaxhar was called "Galacticon" and was to be a woman. It was changed to a male after learning that Madagascar: Escape 2 Africa (2008) had a female villain as well, and production didn't want to be redundant.
  • Originally, Susan Murphy finished the movie back at normal size. It was decided after a screening that it was more fun and satisfying to keep Susan with her super powers and part of the monster team.
  • If this movie was rendered on one computer, it would have taken 4,071 years to render.
  • Including voice actors and actresses, 601 (580 crew, nine post, twelve cast) different people put over 20,466 manweeks into this movie. That's 102,330 mandays or 920,970 manhours.
  • It took a total of five hundred artists to create this movie (the total crew number minus production staff and voice talent). This movie was in production for over four years (from January 2005 to Spring 2009).
  • The movie was originally titled "Rex Havoc", after a lead character that was ultimately cut from this movie. After that, "Creature Feature" was the working title before finally landing on "Monsters vs. Aliens".
  • The first two completed scenes in this movie were "First Contact" and "War Room". These scenes changed very little from the first pitch to the final version. The fight in the end of the movie evolved the most during the course of production.
  • The crew used four different types of 3-D glasses throughout the production.
  • Director Conrad Vernon voiced Mason the chimp in the "Madagascar" film franchise and the Gingerbread Man in the "Shrek" film franchise.
  • Global Stereoscopic supervisor Phil McNally is often referred to as "Captain 3-D".
  • Gallaxhar's facial features were modelled after DreamWorks Animation's C.E.O., Jeffrey Katzenberg.
  • In the opening scene with the two technicians discovering the meteorite, one of them (Technician Ben) plays with a paddle ball, a nod to the 3-D gimmick in House of Wax (1953).
  • At one point, Gallaxhar yells out "Destroy all monsters!" to his clones when he sees Susan, Dr. Cockroach, Ph.D., The Missing Link, and B.O.B., a reference to Destroy All Monsters (1968).
  • When Gallaxhar is sending his message all over the world, at one point he says "You should in no way take any of this personally, it's just business", a reference to The Godfather (1972).
  • When the monsters leave the main power core chamber, B.O.B. forms a "water" tentacle abyss-style to let them slide down. This was a reference to The Abyss (1989).
  • Dr. Cockroach, Ph.D. dancing in sync with the lighted pads is a reference to the arcade game, Dance Dance Revolution (1998), in which you do the same thing, only in sync with the on-screen prompts.

  • Originally, there was another heroic character in this movie called "Rex", a super android who joins the monsters and battle the aliens to save the world. However, he was ultimately cut from this movie when the writers decided to make the "50,000 pound Woman" the new main protagonist, in which they renamed her as Ginormica (Susan Murphy).
  • In the original Rex Havoc novel, The Missing Link didn't exist.
  • Dr. Cockroach, Ph.D. and Insectosaurus are the only characters from the Rex Havoc novel to keep their original names. Susan Murphy/Ginormica was supposed to be called the "50,000 pound Woman" and B.O.B. was supposed to called "Ick!"
  • This movie had been in development since 2002, when DreamWorks Animation acquired the rights to the Rex Havoc novel. About three years later, Conrad Vernon and Rob Letterman were hired to create and start the story from scratch. This movie was then finished during early 2009, which would mean that it took almost five years to create the movie, from pre-production to post.

Spoilers

  • During the fight on the Golden Gate Bridge, Insectosaurus and the Robot Probe didn't throw a single punch at each other. Instead, both of them fight by hitting each other's eyes: Insectosaurus blinds the Robot with her silk, and later on, the Robot shines its light into Insectosaurus' eyes to hypnotize her, although it was unintentional.
  • Gallaxhar's ship exploded in a similar way to how the Mothership exploded in Independence Day (1996). Although, Gallaxhar's ship exploded via self destruction mode, while the Mothership exploded from a nuclear warhead.
  • The Missing Link (Will Arnett) is the only monster who can understand what Insectosaurus is saying.
