  • It was announced in July 2019 that the film would be rated R.
  • Margot Robbie pitched the idea of Birds of Prey to DC and Warner Bros. as a female-led superhero action movie and they agreed with her vision. "I think there's a perception that a PG female-led action film is kind of considered a chick flick," says Robbie, which is why we're going to see an R-rated version of the story. In addition to starring in the upcoming movie, Robbie is also on board as producer with her LuckyChap production company, so her hands are all over the project. Birds of Prey is LuckyChap's largest project to date at $75 million.
  • Harley Quinn was introduced on the big screen in 2016's Suicide Squad with Margot Robbie portraying her and giving birth to the creation of millions of Harley Quinn Halloween costumes. With this new chapter comes a different look for her character. Quinn won't be seen as an object of desire, which is very much on purpose. "That's what happens when you have a female producer, director, writer," says Birds of Prey costume designer Erin Benach. Robbie added, "Yeah, it's definitely less male gaze-y." Robbie had discussed how uncomfortable her outfits were for Suicide Squad, so that has all been altered for this film/
  • The first live-action film appearance of Renee Montoya, a character introduced in Batman: The Animated Series (1992). A previous live-action version appeared on Gotham (2014) played by Victoria Cartagena. A similar character, Anna Ramirez, appeared in The Dark Knight (2008) played by Monique Gabriela Curnen.
  • Harley adopts a hyena in this film as a pet. In the comics, she kept two hyenas named Bud and Lou (named after comic duo Bud Abbott and Lou Costello).

  • This is a spin-off of a character originally created as a love interest for the Joker, a character previously played by Jack Nicholson and Mark Hamill. Ewan McGregor has another connection to both actors. Mark Hamill played Luke Skywalker jn the original Star Wars trilogy, while McGregor played Obi-Wan Kenobi in the prequels. Nicholson appeared in The Shining, while McGregor appeared in the sequel, Doctor Sleep.
  • This is the first theatrically released film in the DC Extended Universe to be Rated R, although the Ultimate Edition of Batman v. Superman: Dawn of Justice (2016) was given the R rating by the MPA.
  • Live-action debut of Cassandra Cain. She is the first character to have a solo ongoing series as Batgirl in 2000. Cain has also taken the aliases of Black Bat, Kasumi and currently, Orphan.
  • The actresses for Huntress and Black Canary have worked with the actresses playing the other's Arrowverse counterparts. Mary Elizabeth Winstead and Katie Cassidy were main cast members of Black Christmas (2006), while Jurnee Smollett and Jessica de Gouw were main cast members of Underground.
  • Related to the Arrowverse, the plot of this movie is apparently that Batman has left Gotham and it's up to a female superhero(es) to save the day. That not only sounds like the premise of the Arrowverse's Batwoman (2019), but also of the earlier Birds of Prey TV show. Related to the Birds of Prey TV series, Harley was barely in it, as a villain fought in the finale of the show. Here not only is she a hero (kinda), she's pretty much the main headliner.
  • Ewan McGregor's recent previous cinematic outing was in Doctor Sleep (2019) where he played a character who has a mantra, when he saw ghosts, would be "False face!" Here, he plays a character who leads a gang called the False Face Society in the comics, and whose gimmick is wearing "false faces" (masks) to cover their real identity.
  • A meme speculating on the type of drug each cinematic Joker might have consumed took on an extra level of irony when the second trailer showed Harley inhaling cocaine.
  • Still on Cassandra Cain, one of the lesser-known criticisms of her was about how she was more or less a DC Captain Ersatz of Marvel's X-23.
  • Gail Simone, considered the definitive writer of the team, wanted to use Cass for the Birds of Prey but couldn't due to executive veto. After all these years, Cass is finally making her big screen debut in the Birds of Prey movie and will be a member of the team.
  • Mary Elizabeth Winstead playing Huntress after having previously acted alongside future Captain Marvel star Brie Larson and Chris Evans who played Captain America in Scott Pilgrim vs. The World has also been a source of amusement for many fans, and she also dated former Superman (and future Atom) Brandon Routh in the same film.
  • Mary Elizabeth Winstead's casting was praised, because she resembles the character. It also helps that she's a popular choice in many a comic book fan-casting for years since Scott Pilgrim vs. The World.
  • Jurnee Smollett-Bell does her own singing in the film.
  • Anthony Carrigan, who portrayed Victor Zsasz on Gotham, expressed his excitement at seeing Chris Messina's take on the character.
  • Gail Simone has been very effusive in her praise for the movie on her social media after seeing it at the press preview.
  • John Leguizamo had discussions for the part of Victor Zsasz before Chris Messina was cast.
  • Lady Gaga was offered a lead role in the film, but she turned down the offer.
  • The Penguin was originally intended to be the main antagonist of the movie, but was scrapped due to his appearance in The Batman portrayed by Colin Farrell.
  • Laura Kinney is considered Cassandra Cain's Alternate Company Equivalent. In 2017's Logan, Laura was aged down from a teenager to an eleven-year-old played by Dafne Keen. Here Cassandra has similarly been aged down to twelve. To add another layer of similarity, the stuntwoman who performed Laura's stunts in Logan, Marissa Labog, is also doing Cassandra's stunts in this project.
  • This is one of three female lead, female-directed comic book movies coming out in 2020. The others being Wonder Woman 1984 directed by Patty Jenkins and Black Widow directed by Cate Shortland. Additionally, the ensemble cast picture The Eternals, directed by Chloé Zhao, has Angelina Jolie (Thena) as its top-billed star.
  • The use of an Edith Piaf song in the trailer makes sense if you remember that Piaf was once The Chanteuse, just as Dinah Lance once was.
  • Chris Messina and Bojana Novakovic previously appeared together in Devil (2010).
  • Joker is often mentioned, but never appears outside of the brief Ace Chemicals flashback (and he's seen from the back).
  • A hyena in a film that has a majority-female cast is an appropriate fit when you take into account that hyenas have a female-dominant hierarchy.
  • Jurnee Smollett-Bell, who played Black Canary in the movie, is the second actress from the sitcom Full House to play the character. The first was Lori Loughlin, who played Carolyn Lance/Black Canary, in the short-lived television series.
  • When Cassandra Cain is in the police station, she's asked by Montoya if she can speak. In the Batman comics, Cassandra doesn't talk because she was raised by her parents to focus on the language of body movements to make her a more skilled fighter.
  • None of the main characters wear skirts in the film.
  • Jurnee Smollett-Bell was inspired by Black Canary as seen on Injustice 2 (2017) for her role in this movie.
  • The egg sandwich that is made for Harley Quinn is not made with chicken eggs, but instead with duck eggs, as Margot Robbie is allergic to chicken egg whites (she gets migraines from them).
  • Ellen Yee is named after Ellen Yin, the Asian Gotham City police officer in The Batman (2004).
  • Though there is no visual post credit sequence, there is however an audio of Harley Quinn quipping to the viewers. Previously there was a similar Easter egg at the end of Avengers: Endgame (2019) of clanging of steel from Iron Man (2009)
  • The first trailer prominently features a song that appears to be by Edith Piaf, who is well-known to Christopher Nolan fans as the singer behind the song 'Non Regette Je Nien' which is used in Inception to signal it's time for Cobb's team to wake up from their dream heist. Christopher Nolan also produced the first two DCEU films (Man of Steel and Batman v Superman) which were supposed to originally be sequels to The Dark Knight Trilogy.
  • When Harley Quinn is leaving the police precinct she points to a wanted poster and says "Hey, I know that guy!". The wanted poster is that of Captain Boomerang with whom she worked with in Suicide Squad (2016).
  • Coincidentally, the unit publicist for "Birds of Prey" is Heidi Falconer.
  • When Renee Montoya is in her apartment, her television is playing a clip from an episode of daytime soap opera THE DAYS OF OUR LIVES and featuring actress Arleen Sorkin. Sorkin was the original voice of Harley Quinn in BATMAN: THE ANIMATED SERIES. This specific clip is what inspired writer Paul Dini to create the character of Harley.
  • In Montoya's room when she receives the text from Black Canary there is a woman in a clown suit playing on the tv on her dresser. This is a scene from 'Days of Our Lives' and the woman is Arleen Sorkin. Not only is Arleen the original voice of Harley Quinn on 'Batman: The Animated Series' but THIS SCENE was the inspiration for the character of Harley. Paul Dini, who was friends with Arleen, saw the scene one day when he was home sick and was inspired to create the character with Arleen's voice in mind.
  • Love Rollercoaster by Ohio Players was played in this movie wherein Mary Elizabeth Winstead is as The Huntress. Love Rollercoaster was also played in Final Destination 3 (2006) wherein Mary Elizabeth Winstead portrayed as the protagonist.
  • Harley only has a single hyena rather than two because the effects for its photorealistic animation were so intensive they could only afford one.
  • In the background of one scene featuring Renee Montoya is a brief shot of a TV playing an old episode of Days of Our Lives. It features the sequence in the show in which Arleen Sorkin's character, Calliope Jones, dresses up as a clown, which was the original inspiration for the character of Harley Quinn and what landed Sorkin the role as the original Harley.
  • When Harley remembers her heart being broken before she met the Joker. She recalls two guys and one girl - and the girl is animated in exactly the style of Poison Ivy in Batman: The Animated Series.
  • Montoya gets suspended from the police force by a dirty cop named Tim Munroe. In the comics, Munroe is corrupt, and ultimately killed an orphan Ivy was protecting. Needless to say, she got her revenge.
  • When Harley Quinn rampages through the police station, she pauses to declare that she recognizes a face on a wanted poster. It's Jai Courtney's Captain Boomerang, from Suicide Squad. It looks as though Harley isn't the only former Squad member to have broken out of Belle Reve.
  • Most of Harley's outfits in the movie are street clothes, but during the Boopy Trap fight scene, Renee Montoya wears a bustier that's directly inspired by her Animated Series look. Similarly, Dinah pulls out Harley's Suicide Squad t-shirt
  • It's slightly different in Birds of Prey, but the New 52 era of DC Comics actually reinvented Black Canary to be a singer in a punk rock band. We see echos of that idea here where she's a lounge singer for Roman's club
  • Harley briefly talks about surviving a bomb in the neck, an obvious nod to her time with the Suicide Squad which kept its members in line by implanting bombs in each of their necks.
  • Harley gives an abbreviated version of her personal history, including her time spent as an orphan, her stint as a psychologist in Arkham and so on. All of that comes directly from her animated series origins.
  • Harley's favorite nickname for Joker, "Puddin," gets a shoutout during her break up story
  • We don't get to see too much of Gotham's landmarks no Wayne Manor, no Gotham Zoo, no Crime Alley in Birds of Prey, but we did get a couple of set-pieces that take place in classic territory. Ace Chemicals is the most obvious locale. Harley blows up the factory, where a man named Jack Napier turned into the Joker in the comics, as a "middle finger" to her former beau. Amusement Mile, meanwhile, provided the setting for the movie's final act, and was often seen as a haunt for Harley and Joker in Batman: Arkham City.
  • Roman keeps an extensive collection of exotic masks, as he did in the comics, even before he adopted his villainous alter ego.
  • Harley take on Black Mask at the so-called "Founders Pier" though that isn't a location we know from Gotham City, it seems like it could be a mashup of Founders Island in the Arkham series of games and Gotham Pier in various Batman movies and comics. That's not the only landmark familiar to gamers, as Amusement Mile, the location of the Funhouse is a key location in the North East of Gotham in both the Batman comics and the award-winning Batman: Arkham games.
  • The "famous Gotham artist" who made Roman's statue could be the Bat-family villain Grotesque or the Batman '66 villain known as the Clock King who pretends to be an artist when he isn't committing bizarre time-based crimes.
  • Harley and Cassandra are watching a Tweety and Sylvester cartoon, and there's a Porky Pig VHS tape on top of the TV, this is not just a cool Warner Bros. animation nod, but also pays homage to the fact that the film really feels like a live action Looney Tunes cartoon.
  • The Golden Lion crime family could be a nod to the similarly named award that Joker (2019) took home at the Venice Film Festival the year before.
  • One of Sionis's goons in the funhouse near the end was dressed like DC Comics character, B'wana Beast.
  • The movie is changing its theatrical name from Birds of Prey (and the Fantabulous Emancipation of One Harley Quinn) to Harley Quinn: Birds of Prey, according to ComicBook.com.
  • Robbie said that she did not feel comfortable in her tattered clothes and hot pants. Therefore, in Birds Of Prey, Harley wears more comfortable yet colourful garments. However, 'Daddy's Lil' girl' becomes a tattoo on Harley's collarbone in the movie, paying tribute to how famous the costume got initially, being the top searched Halloween costume that year.
  • post-credit voiceover, Harley makes fun of those who are still waiting in the theatre but also says, "Batman F-" before she is cut off. The message is pretty clear we believe, that Batman loves bats in a not very family-friendly manner, according to Harley.
  • Helena/Huntress's motorcycle is a Triumph Speed Triple S.
  • When The Birds of Prey officially form, Dinah and Helena are wearing outfits much like their comic book counterparts with Dinah in leather and fishnets and Helena wearing a purple ensemble, complete with a mask.
  • Harley's Marilyn Monroe-inspired delusion that she goes into after getting violently interrogated resembles the fantasy worlds that Baby Doll goes to when she's dealing with creepy men in 'Sucker Punch' .
  • Harley is shown to be obsessed with food throughout the movie. She is always looking for something to eat when she's not fighting bad guys, such as pursuing a bacon, egg, and American cheese sandwich, taking refuge at a Taiwanese food shop where she orders extra-spicy Mongolian beef and robbing a grocery store because she's out of groceries (despite living in a restaurant).
  • Out of the main five characters, Helena, Harley, Renee, and Cassandra are all relative newcomers to the Gotham corner of the DC universe (given that it's eighty years old). Helena Bertinelli was created in 1989 to replace Helena Wayne who was previously Huntress before the Crisis on Infinite Earths reboot in 1986. Harley and Renee were created in 1992 for Batman: The Animated Series. Renee appeared in the main DC Universe a few months before she was in the show but Harley didn't make the move until 1999. That was the same year that Cassandra was created for the Batman: No Man's Land Batfamily Crossover. Black Canary is the only "classic" character being used (created in 1947) but Dinah Lance didn't get powers or take over for her mom until 1983. All of them are beating much older characters to appearing in this universe like Dick Grayson or Barbara Gordon.
  • Two cops in the film are named Dimm and Tini, referencing Harley's creators Bruce Timm and Paul Dini.
  • In the comics, Cassandra Cain was mute when she first appeared, and only gradually acquired the ability to speak. In Cassandra's first scene in the police station, it seems at first that the movie version might also be mute, but then she coughs to clear her throat and speaks normally for the rest of the film.
  • Once she uses her powers, Jurnee Smollett said her posture is based on Dinah's Canary Cry from Injustice 2.
  • Victor Zsasz working for Roman Sionis is inspired by the "Hush Money" Streets of Gotham arc, where Black Mask took Zsasz under his patronage and funded his gladiatoral slaughterhouse in exchange for helping save Mask's life from Firefly.
  • When Roman is interrogating Harley at his club he threatens to have her face cut off and pickled... something that the Joker actually did have happen to him (at his own request) at the beginning of the New 52 era of the Batman comics.
  • Renee Montoya and Cassandra Cain are referred to by their civilian names, while the rest are introduced by their code names (Harley Quinn instead of Harleen Quinzel, Black Canary instead of Dinah Lance, and Huntress instead of Helena Bertinelli). Then again, neither Cassandra nor Renee use their comic book superhero identities in this story anyway. On the villains side, Roman is only ever referred to as Black Mask once.
  • Batman stays out of Gotham, for once, not even having a cameo but still getting mentioned at least twice. In fact, he seems to be absent, as Sionis is stated to have basically controlled the entire city. It's left to a trio of women who would form the Birds plus a reformed (?) supervillain to take him down. Speaking of which, Commissioner James Gordon and Detective Crispus Allen, both from GCPD and introduced in Justice League, are conspicuously absent.
  • Each Action Girl of the film has her own distinct close combat style: Harley uses gymnastics. Huntress uses shoulder throws. Black Canary favors kicks. Renee Montoya prefers punches.
  • When Harley is attacking the GCPD headquarters, there is a mugshot of Captain Boomerang, and she notes "I know this guy".
  • Huntress has the least screen time of the Birds, but she has become the most popular of them, causing many to demand a standalone Huntress film.
  • This interpretation of Sionis is an interesting take on his ties to Bruce Wayne. In some comics, Bruce and Roman were 'friends' as children (or at least the Sionis parents wanted to associate with the Waynes to boost their own social standing), which leaves to Sionis becoming the criminal version of Batman with varying degrees of skill. In this adaptation, while Sionis sets out to present an intimidating persona to Gotham's criminals in his 'Black Mask' guise, in practice he is a petty spoiled playboy who represents what Bruce Wayne could be if he really was the rich idiot he pretends to be while having absolutely no thought for the consequences beyond what benefits him.
  • The Logo Joke depicts a frowny face on the DC logo. In one sense it represents Harley having a bad time at the beginning, but in another sense it represents Harley doing her best to distace herself from a villain whose trademark is a smile.
  • Harley destroying Ace Chemicals, is similar to Batman (1989) when he destroys Axis Chemicals.
  • Harley is happy to remove her various Joker tattoos over the course of the film, with the "J" turned into a mermaid and "Cups" added to the word "Puddin." The mermaid is probably a nod to the Gotham City Sirens.
  • Notice a katana in Harley's box of arsenal at Amusement Mile (she worked with Katana in Suicide Squad). While this is unlikely to be Katana's actual blade, it suggest Harley liked the weapon and wanted one of her own.
  • The shot of Harley Quinn as a roller-blader is lifted straight from 2013's Harley Quinn #1, and she has a number "92" - referencing the year of her debut in Batman: The Animated Series.
  • Both Bernie the Beaver and Harley's pet hyena are established parts of Harley Quinn lore. As in Birds of Prey, the comic book version of Bernie is a stuffed animal who, Harley is convinced can talk (he's even had his own character arcs). Harley Quinn's hyenas, meanwhile, were introduced in Batman: The Animated Series and made the jump over to the comics with their mistress. They're traditionally named Bud and Lou, after Abbot and Costello, but those names were picked by the Joker and really wouldn't work in a film where Harley is getting over her ex. The DCEU hyena is called Bruce - after "that hunky Wayne guy." Harley clearly has quite a thing for Bruce Wayne, even wearing the name "Bruce" on a dog tag.
  • Harley's dad traded her in for a can of beer, the beer is called "DINI," a reference to Harley's creator Paul Dini.
  • According to the list of "grievances" that Black Mask has with her, Harley Quinn voted for Bernie Sanders. That may not mean anything about Harley's political leanings, though, given how whimsical she is, she may have cast her vote for Bernie just because his name reminded her of her beaver.
  • In one scene, Harley Quinn comments that she knows Gotham's East Side better than anyone. This is the poorest part of Gotham, and the notorious Crime Alley - site of the Wayne murders - is situated there. The Joker has never been massively active in the East Side, so this may hint that the nun orphanage Harley went to as a child was situated there. Of course, Harley Quinn isn't necessarily a reliable narrator, so the nuns may not have been quite so bad as she claims.
  • There are several nods to Tom Taylor's much-loved Injustice series, notably in the entire dynamic between Harley and Black Canary. This is most obviously called out when Harley storms into the police station, complete with an actual quote. "I'd like to report a terrible crime," Harley quips, before unleashing mayhem on the GCPD
  • There's a throwaway mention of Robinson Park, a classic Batman location named after Jerry Robinson, the man who created the Joker.
  • ACE Chemicals is an established part of the DCEU, with this specific location appearing in Suicide Squad. Billy Batson practiced his superpowers at another ACE Chemicals plant in Shazam! as well. Later in the film, when Harley needs a place to arrange a meet, she chooses the Joker's turf - Amusement Mile. An abandoned amusement park in North Gotham, this is traditionally the Joker's base of operations, most famous for its role in The Killing Joke. It seems the Joker has decided to leave that for Harley, because he's taken all his equipment out and left a crate packed with Harley's few belongings. Look carefully, and you'll spot "HAHAHAHAHAH" scrawled on one wall in a similar style to the Joker's laugh in The Dark Knight Returns. It also resembles the distinctive tattoos on Leto's Joker.
  • Harley spends the entirety of the movie, struggling to get out of the Joker's shadow. Curiously, though, there's next to no hint of Jared Leto's Joker. All the animations show a far more traditional version of the Clown Prince of Crime, and Harley rattles off his comic book nicknames when she's trying to impress Cassandra Cain. Leto's version of the Joker wasn't exactly a hit in Suicide Squad, and there's been intense speculation he'll be recast. His deliberate absence, even carefully excised in flashbacks from Suicide Squad, seems to hint that will indeed be the case.
  • Cassandra Cain bears absolute no relation to her comic book counterpart bar being an orphan. There's only one nod to the Cassandra from the comics, in that she initially struggles to speak to Montoya - a reference to the fact that the comic book Cassandra is actually mute.
  • Huntress' origin story is loosely adapted from Greg Rucka's Batman/Huntress: Cry for Blood limited series, where she was a member of the Bertinelli family who witnessed her entire family being slaughtered by a rival Gotham gang. The Huntress: Year One miniseries established she was trained in Sicily, but most of the other details have been switched up.
  • Renee Montoya is presented in a more comic book-accurate fashion, right down to being the DCEU's first out lesbian character. She appears to end Birds of Prey as an active vigilante, perhaps taking up her comic book codename "The Question." The last scene shows both Black Canary and Huntress in familiar costumes from the comics.
  • Dinah Lance - aka Black Canary - has inherited her powers from her mother. This is a nod to the comics, where Black Canary remained active and youthful for so long that DC retconned there to have been two: a mother and a daughter, both named Dinah.
  • Black Canary seems heavily inspired by Tom Taylor's Injustice, and one specific shot - where she unleashes her Canary Cry - is lifted straight from Injustice: Year Two.
  • There are two references to Poison Ivy: When Harley remembers her heart being broken before she met the Joker. She recalls two guys and one girl - and the girl is animated in exactly the style of Poison Ivy in Batman: The Animated Series. Montoya gets suspended from the police force by a dirty cop named Tim Munroe. In the comics, Munroe is corrupt, and ultimately killed an orphan Ivy was protecting. Needless to say, she got her revenge.
  • Sionis rants about his family background. He should have inherited the Janus Corporation, which is shown several times in the background (usually with the "J" blocked). Janus was also the parent company of ACE Chemicals in the comics. There's actually a Janus Corporation Easter egg in Justice League, when Batman and a Parademon fight on a sign for Janus Cosmetics.
  • A number of gags on Black Mask's real name, "Roman Sionis," and even gets in a scene where he addresses his thugs in the "Friends, Romans, countrymen" formula.
  • Just as in the comics, Black Mask is obsessed with heads and masks. His thugs all don crazy masks in their attack on Amusement Mile, hinting at their being the "False Face Society" from the comics.
  • Production designer K.K. Barrett makes a cameo as Dr. Aguilar, the scientist who gives Black Mask a botox injection.
  • While the film doesn't have a post-credits scene, it does feature a voice-over in which Harley Quinn declares that "Batman f--" - before being cut off. In the current Harley Quinn DC Universe animated series Harley has repeatedly insisted that Batman f**** bats.
  • At one point, Harley suffers a concussion and dreams herself into a classic musical interlude in which she plays Marilyn Monroe singing "Diamonds are a Girl's Best Friend." The whole thing is an homage to 1953's Gentlemen Prefer Blondes. In amusingly meta touch, this isn't the first time Ewan McGregor has appeared in an adaptation of that number. It was also featured in Moulin Rouge!, with McGregor's character falling in love with Nicole Kidman's Satine during the song, Nicole Kidman was in Batman Forever (1995). She played a psychiatrist.
  • Toward the end of the film, Harley uncovers a chest of her old things - grenades, her old Suicide Squad outfit, and most crucially, her old corset. Though Harley most notably wore a corset in her New 52 reimagining, the corset is also notably reminiscent of her original full body harlequin outfit.
  • When Zsasz shows his scars and explains that he has made a cut for every "pretty bird he has set free", he's dodging around the reality of the scars, as every cut he makes is for someone he's killed - with his comic form being obsessed with killing enough people to mark every part of his body. Also, crucially, Zsasz is generally not limited to "pretty birds" but rather anyone with a pulse within stabbing range.
  • During the flashbacks to her violent past, we see Helena in a church, praying with a rosary. In the comics, Helena is a devout Catholic who carries a rosary on her, even when in costume.
  • The New 52 era of DC Comics actually reinvented Black Canary to be a singer in a punk rock band. We see echos of that idea here where she's a lounge singer for Roman's club.
  • Most of Harley's outfits in the movie are street clothes, but during the Boopy Trap fight scene, Renee Montoya wears a bustier that's directly inspired by her Animated Series look. Similarly, Dinah pulls out Harley's Suicide Squad t-shirt Harley briefly talks about surviving a bomb in the neck, an obvious nod to her time with the Suicide Squad which kept its members in line by implanting bombs in each of their necks.
  • After open season is officially declared on Harley, one of Roman's hired goons comes at her wielding a crowbar, which just so happens to be the now infamous weapon of choice Mr. J decided to use on Jason Todd, the Robin he murdered.
  • Harley and Cass camp out in her apartment watching Looney Tunes on TV while hiding from the cops--you know, in case you missed Harley's own personal Looney Tunes stylings, including her very Bugs Bunny "disguise" when breaking into the police station.
  • We don't get to see too much of Gotham's landmarks no Wayne Manor, no Gotham Zoo, no Crime Alley in Birds of Prey, but we did get a couple of set-pieces that take place in classic territory. Ace Chemicals is the most obvious locale. Harley blows up the factory, where a man named Jack Napier turned into the Joker in the comics, as a "middle finger" to her former beau. Amusement Mile, meanwhile, provided the setting for the movie's final act, and was often seen as a haunt for Harley and Joker in Batman: Arkham City.
  • While Harley is getting her clock cleaned by Ewan McGregor's Roman Sionis, she suddenly starts hallucinating, imagining herself as Marilyn Monroe's character, Lorelei, in the iconic song-and-dance number from 1953's Gentlemen Prefer Blondes. She even gets to perform her own anarchic version of "Diamonds Are a Girl's Best Friend" before being smacked back into reality.
  • During the animated recap of her life, we see Harley Quinn's black-and-red costume as she rises from the vat in Ace Chemicals.
  • The rival mafia don who kills the Bertinellis is Don Galante. In the comics the Galante family are one of Gotham's five mob families that make up the city's La Cosa Nostra.
  • In the comics Renee Montoya quits the police and becomes the Question.
  • Roman's "fuck family" rant is the closest this character feels to his earliest comics appearances, where he resented his parents and actually created his mask from the wood of his father's coffin.
  • Sionis keeps an extensive collection of exotic masks, as he did in the comics, even before he adopted his villainous alter ego.
  • Renee is the first canonically gay character in either a Marvel or DC movie and when we're introduced to her ex-girlfriend (played by Ali Wong) it's a nice nod to the queer history of the character who once dated Kate Kane's Batwoman.
  • In the DC Comics, Cassandra Cain is the daughter of Lady Shiva and David Cain who train her to be an assassin.
  • When Cassandra Cain is initially unable to respond to Montoya's question in the precinct, it's a nod to how the character couldn't speak in her early appearances. This was due to her brutal training by her father which put the ability to kill above the ability to communicate. Also in the comics, Cassandra Cain wore the mantle of Batgirl for a number of years.
  • Harley mentioning that she once stole "Eleanor Rosevelt's nudes" for the Joker is especially funny because the first lady was actually introduced in to the DC universe canon as a character in 1981's All-Star Squadron #3.
  • During the film, Harley is seen dressed as Marilyn Monroe's character from 1953's "Gentlemen Prefer Blondes." The big change here is that Quinn has an updated version of the gown with pants instead. Costume designer Erin Benach told Insider they almost did a completely different outfit for Quinn here. "It wasn't even really on the page or decided amongst us that it would be the same Marilyn outfit," said Benach "There were talks of it being something totally different and new, like way more Harley." The idea to transform the iconic look and update it came to Benach while in a research library. "I remember the moment where I just went, 'Oh my God, the best idea is just to take the exact Marilyn outfit and put her in pants. Turn it into pants,'" said Benach. "It was just a light bulb moment. It hit and I told [director] Cathy [Yan] and Cathy was like, 'Brilliant. Done. Do it.'"
  • Third movie Ewan McGregor plays a bisexual/homosexual, after Velvet Goldmine (1998) and I Love You Phillip Morris (2009) which also starred Jim Carrey as the main lead, who coincidentally play The Riddler in Batman Forever (1995).
  • Montoya's revolver, is a Smith & Wesson Model 36.
  • The first DC Extended Universe film to not be in 3D.
  • It is said frequently that Renee Montoya talks/acts as if in an 80's cop show. When running after Harley, Montoya growls in homage to Sgt Belker from 80's police drama 'Hill Street Blues'.
  • Harley uses a M79 Grenade Launcher loaded with a variety of less-lethal rounds during her assault on the police station. The flip-up sight is removed and the weapon decorated with various markings, including the words "Fun Gun" on the barrel.
  • Though they share no scenes, Ewan McGregor (The Black Mask) and Mary Elizabeth Winstead (The Huntress) were dating during filming, and are still a couple as of the film's release.
  • Jared Leto filmed a cameo as The Joker, but it was eventually cut.
  • Bruce the hyena CGI animation is similar to the CGI animation of the Hyenas from the remake of, The Lion King (2019).
  • Helena's Huntress mask has retractable lenses similar to Selina Kyle's in The Dark Knight Rises (2012).
  • Dinah mistakenly refers to Helena's crossbow as a bow and arrow, referencing Oliver Queen/Green Arrow who Helena was married to in the comics.
  • Dinah uses Harley's bat from Suicide Squad (2016) as her weapon during the fight in The Booby Trap.

Spoilers

  • First time we see the "Canary Cry" in the DCEU.
  • During the police station break in sequence, there are several wanted posters around the precinct. One of them being Jai Courtney's George Harkness (Captain Boomerang) from Suicide Squad (2016) Harley Quinn quips to it by saying "oh I know you"
  • In the movie, Harley Quinn (in her imagination) sang and danced to the song "Diamonds Are a Girl's Best Friend", which is also a feature song in the movie: Moulin Rouge! (2001), starring Ewan McGregor (who plays Black Mask) as the lead male cast
  • Including a hyena in a film that has a majority-female cast is an appropriate fit when you take into account that hyenas have a female-dominant hierarchy. Also, Bruce, Harley's pet hyena is seemingly killed midway through the film when villains attack Harley's apartment, but in the last scene is revealed to have survived. When they are reunited, Harley comments Bruce apparently has "nine lives, like a cat" (paraphrased). Despite looking like canids, hyenas actually are feliforms instead of caniforms, which make them (very) distant relatives of cats.
  • Many fans and critics have praised Ewan McGregor's interpretation as the villainous Roman Sionis, calling him one of the best parts of the movie, even though he has relatively little screen time and dies at the end, eliminating any possibility of more of him.
  • Dinah's car which Harley steals at the end is a, 1987 Jaguar XJ-S 5.3 V12 Convertible Hess & Eisenhardt [XJ27].
