Gal Gadot's family and Patty Jenkins's son have a cameo at the end of the film: Gadot's elder daughter and Jenkin's son throw a snowball at her, and Gadot's younger daughter and husband appear on the carousel.
In Greek mythology, the Amazon Asteria was one of those slain by Heracles when he came to Themyscira to take Hippolyta's girdle as one of his famous Labors. Asteria is also the name of the Greek goddess of stars.
Asteria's gold armor is based on the armor Wonder Woman wears in Alex Ross graphic novel "Kingdom Come." Ross commented in an interview that he was upset the studio didn't compensate him for using his design in other media besides comics.
When Diana, Steve and Barbara visit the shaman, Diana deduces that the dreamstone was created by Dolos, a god of evil mischief whom she describes as a duke of deception. In the Wonder Woman comic book, the Duke of Deception was a recurring super-villain in the early days (1940s) of the Wonder Woman comic. He was a servant of the god of war, Mars (Ares).
In the montage early in the film featuring 80s Washington DC, several teenage girls shoplift a pair of sunglasses from a store called Commander Salamander. This was a real store in the Georgetown neighborhood of DC that specialized in new wave and punk attire, becoming a popular local destination throughout the '80s and '90s before it closed in 2010. Its reappearance during filming thrilled local residents who remembered the shop, and was featured in several local blogs and papers.
Hans Zimmer had previously announced that he would retire from composing for superhero films after Batman v Superman: Dawn of Justice (2016), which featured Wonder Woman's cinematic debut and teamed her up with Batman and Superman, whose films he had already composed scores for. However, he accepted to compose the score for X-Men: Dark Phoenix (2019), and returned to compose for this film.
Barbara Minerva (Cheetah) is seen indulging in fur clothing. This is an homage to Priscilla Rich, the first Cheetah (Barbara was the third, and most famous), who enjoyed wearing animal furs and wore a magical fur cheetah costume.
Pedro Pascal describes Max Lord as a dream seller: "He encompasses a component of the 1980s culture which is: get whatever you want, however you can, you're entitled to it! It's f***ing greed, of course, and that costs a great deal. But it's also about: How do you be your best self? How do you win? So he's definitely the face of success."
This film is the first live action appearance of Cheetah. All of her previous appearances were in animated television programs (specifically Challenge of the Superfriends (1978), Justice League (2001), and Batman: The Brave and the Bold (2008)) and direct-to-DVD animated films featuring the Justice League. She was never featured in the 1970s live action television series. She has also been featured as a playable character in Justice League video games starting with Justice League: Task Force for the Super Nintendo in 1995.
The film has had seven release dates, the first being December 20th, 2019. Then it was moved up to November 8th, 2019 in order to avoid competing against Star Wars: Episode IX - The Rise of Skywalker (2019). Once it was announced that the 25th James Bond film was to leave its originally scheduled November 1st spot, Warner Bros. moved the film's release up another week, in order to take an extra week advantage. The fourth was when it was pushed back by 7 months to June 5th, 2020 as Warner Bros. realized the success of the first film's June 2nd, 2017 release. The fifth change was made on March 24th, 2020 when it was moved to August 14, 2020 due to concerns about the COVID-19 virus. It was again moved to Oct. 2 in June when Warner Brothers shifted its entire schedule of upcoming films. Then in September 2020, it was pushed once more to December 25th, 2020 and released on streaming at the same time.
Patty Jenkins picked the 80s as the film's setting because she saw it as "the height of Western civilization and society, and so it offers the opportunity to explore how Wonder Woman would deal with the types of villains that come from that era."
In a brief shot outside Max Lord's HQ, as police and crowds are running in the background, a motorcycle cop in beige passes right behind Steve Trevor (Chris Pine) as he walks toward the HQ with Diana. The cop is wearing the California Highway Patrol uniform, a homage to the 80s police show CHiPs (1977), which starred Pine's father Robert Pine as Sergeant Getraer.
Stuart Milligan is credited simply as POTUS and the president's name is never spoken in the film, but the President in 1984 (in real life) was Ronald Reagan. Milligan previously played another famous president, Richard Nixon, in an episode of 'Doctor Who.'
Simon Stagg, Maxwell Lord's business partner early in the film, is based on the DC Comics character of the same name; an unscrupulous businessman who is both adversary and father-in-law to Rex Mason, aka the superhero Metamorpho.
At the start of the film Diana has a news article clipping from 1918 with the headline saying "The Great War Ends!". Also, if you look closely, you can see a picture of General Erich Ludendorff (played by Danny Huston), one of the villains from the previous film.
The Wrap reported in March 2020 that WB executives were considering releasing the movie directly on streaming instead of theaters due to the health concerns of the Coronavirus. They ended up releasing it on HBO Max and in theaters on Dec. 25 that year.
Diana's apartment is located in (and was filmed at) the Watergate complex of apartment, office, and hotel buildings in the Foggy Bottom neighborhood of Washington, D.C. The complex lent its name to a notorious political scandal: the Nixon administration's bungled attempts to cover up its involvement in the June 1972 break-in at the Democratic National Committee headquarters housed in the Watergate office building.
The third film in the WB/DCEU to reference Italy's Ancient Roman past when the Dreamstone is revealed to have caused the disappearance of King Romulus in a whirlwind in 716 B.C. and, in the year 476 A.D. when the last Roman Emperor Romulus Augustlus was assassinated he was reported to have the stone in his possession. In Aquaman the statue of King Romulus appears when Arthur Curry and Mera were in Erice, Sicily to look for Atlan's Trident after finding a map in the Kingdom of the Deserters that led them there. In Shazam! Freddy Freedman references the Romans to Billy Batson.
In the scene at the Smithsonian's Air & Space Center, Chris Pine has an interaction with someone dressed as an astronaut. In 1984, the original filming model of the USS Enterprise from Star Trek: The Original Series (1966) hung from the ceiling just off frame to the right of that scene. Chris Pine played Captain Kirk in three Star Trek films.
In the scene in Diana's apartment when Steve Trevor looks into the mirror on the wall and sees the face of the man he 'leaped' into is a homage to the TV series Quantum Leap when Sam Beckett would look into a mirror and see who he has leaped into.
Maxwell Lord's physical appearance and line of work have led many viewers and critics to believe that he is supposed to be a derogatory portrayal of Donald Trump. Patty Jenkins has repeatedly denied these comparisons.
The song played at the end of the film when Diana is has a conversation with the man Steve Trevor's spirit possesses is "I won't leave you" by Clinton Shorter. The song was previously used in the disaster film Pompeii (2014). Curiously, one of the film's characters in Pompeii, Atticus, is played by fellow WB/DCEU actor Adewale Akinnuoye-Agbaje who appeared as Killer Croc in Suicide Squad (2016).
Third film in the WB/DCEU to reference Italy. The first was Aquaman (2018) during the Sicily battle with Black Manta and the second being Birds of Prey (2020) when a young Helena Bertinelli is taken to live and train as the Huntress. Max Lord says to his son Alistair that "Rome was not built in a day".
Gabriella Wilde's character Raquel, Maxwell Lord's secretary, seems to speak with an Eastern European accent, pronouncing the trilled "r" as well as all plosive consonants ("s", "t", "f", etc.) clearly. This may be a nod to Donald Trump's wife Melania, who is of Slovenian descent.
In the final scene when Wonder Woman is talking to the people of the world to renounce their wishes, the score "A Beautiful Lie" from Batman v Superman: Dawn of Justice (2016) is playing in the background.
Despite having Hans Zimmer compose the score, the scene where Diana leaves Steve Trevor to fly off to Max Lord's base plays the main theme from Sunshine (2007), composed by John Murphy. Murphy will also score the soundtrack of the DCEU film The Suicide Squad (2021).
There are multiple hints that Kristen Wiig turns into Cheetah earlier in the movie - Diana wears Cheetah print shoes, the soundtrack playing at the reception is Frankie Goes to Hollywood's "Welcome to the Pleasuredome" which opens with the lyrics 'the animals are winding me up' and 'using my power I sell it by the hour'.
