Development for a live action Wonder Woman feature film began in 1996, with Ivan Reitman attached as producer and possible director. In 1999 the project became attached to Jon Cohen, who adapted Wonder Woman for producer Joel Silver, with the hope that Sandra Bullock would star. By 2001, Todd Alcott was hired to write the screenplay, with Silver Pictures backing the project. At that time, performers such as Mariah Carey and Catherine Zeta-Jones were also rumored to be possible candidates for the role of Wonder Woman. Leonard Goldberg focused on Bullock who said that she was approached for the role. Lucy Lawless, the star of Xena: Warrior Princess, was also under consideration, though she stated that she would have been more interested if Wonder Woman was portrayed as a "flawed hero". The screenplay went through various drafts written by Alcott, Cohen, Becky Johnston, and Philip Levens, and by August 2003, Levens had been replaced by screenwriter Laeta Kalogridis.
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.
