Originally signed for three feature films, with Wonder Woman and Justice League being her second and third films, Gadot signed an extension to her contract for additional films. Jenkins initially signed for only one film, but in an interview with Variety, Geoff Johns revealed that he and Jenkins were writing the treatment for a Wonder Woman sequel and that he has a "cool idea for the second one". At the 2017 San Diego Comic Con, Warner Bros. officially announced a sequel would be released on December 13, 2019, and would be titled Wonder Woman 2; the date was later moved up to November 1, 2019, to avoid competition with Star Wars: The Rise of Skywalker. Later, Jenkins was officially signed to return as director, with confirmation that Gadot will be returning as the titular role. Days later, the studio hired Dave Callaham to co-write the film's script with Jenkins and Johns. On March 9, 2018, Kristen Wiig was confirmed to play Cheetah, the villain of the film. Later that month, it was announced that Pedro Pascal would have a key role in the film. In May 2018, long-time DCEU producer Zack Snyder confirmed on social media platform Vero that he, along with wife Deborah Snyder, will serve as producers on the Wonder Woman sequel. In June 2018, the title of the film was announced to be Wonder Woman 1984. A third film was announced in January 2019 to be taking place in the present.
In the Golden Age, Wonder Woman adhered to an Amazon code of helping any in need, even misogynistic people, and never accepting a reward for saving someone; while conversely, the modern version of the character has been shown to perform lethal and fatal actions when left with no other alternative, exemplified in the killing of Maxwell Lord in order to save Superman's life.
This version was conceived of as a prequel to the first live-action, theatrical appearance of Wonder Woman, in the 2016 film, Batman v Superman: Dawn of Justice, placing Wonder Woman in the 1910s and World War I (a decision which differs from her comic book origins as a supporter of the Allies during World War II). As for story development, Jenkins credits the stories by the character's creator William Moulton Marston in the 1940s and George Perez's seminal stories in the 1980s in which he modernized the character. In addition, it follows some aspects of DC Comics' origin changes in The New 52 reboot, where Diana is the daughter of Zeus. Jenkins cited Richard Donner's Superman as an inspiration.
After preventing a terrorist attack at a refugee camp in Greece, Wonder Woman returned to a government facility in the United States and was examined by a sickly doctor, Dr. Shannon Crawford. That evening, Diana attended the wedding of Etta Candy's brother, where she discovered a bomb seconds away from detonation hidden underneath one of the tables. She was able to contain the blast, but Etta was injured by a piece of shrapnel. She returned Etta to Dr. Crawford who removed the shrapnel, before touching Wonder Woman with an Amazon-strength sedative she had developed, leaving Diana too weak to fight back. Dr. Crawford told Diana that she had a rare genetic illness, and that she intended to use Diana's Amazon blood to develop a cure, saving her life as well as providing life-saving treatment for others afflicted with the same disease. Diana awoke to discover Crawford had developed Amazonian strength as a result of the blood transfusion. She was able to bind Dr. Crawford in the Lasso of Truth, which rejected the lie and restored Crawford to her previous state. Having lost hope for a cure, Crawford injected herself with the sedative, killing her. Wonder Woman was too late to stop her, but she understood Crawford's decision to end her pain and held her as she died.
Marc DiPaolo introduces us to Wonder Woman's creator and history and he demonstrates how she is a "WWII veteran, a feminist icon, and a sex symbol" all throughout her "career". Wonder Woman stars in multiple films and is most commonly known for her red, white and blue one piece, and her tall, sexy assertiveness. What many people don't know is that she is a big part of history in the comic and superhero world because of how her character influences real life people of all ages, sexes, ethnicities, and races. "Marston created the comic book character Wonder Woman to be both strong and sexy, as a means of encouraging woman to emulate her unapologetic assertiveness." Charlotte Howell notes in her essay titled "'Tricky' Connotations: Wonder Woman as DC's Brand Disruptor" that Wonder Woman is, "inherently disruptive to masculine superhero franchise branding because, according to her creator William Moulton Marston, she was intended to be 'psychological propaganda for the new type of woman who, [he] believe[d], should rule the world.'"
Additionally, Mayling Ng, Florence Kasumba, Madeleine Vall Beijner, Hayley Jane Warnes and Ann Wolfe portray Orana, Acantha, Egeria, Aella and Artemis, respectively, all of whom are Amazons. James Cosmo appears as Douglas Haig, Steffan Rhodri appears as Darnell, and Dutch supermodel Doutzen Kroes portrays the Amazon Venelia. Samantha Jo was cast as the Amazonian Euboea, and previously played the Kryptonian, Car-Vex, in Man of Steel. Zack Snyder also makes a brief cameo appearance in the film as an unnamed soldier.
Impressed by this unknown woman's self-sacrifice, the Amazons entombed her with honors and clothed her in armor displaying the American flag pattern on her uniform, which they assumed were her heraldic colors. Trevor's legacy was also the primary reason why Ares arranged for Steve Trevor to bomb the island, as he could not resist the irony of the heroine's son unwittingly killing her admirers.
