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went through various drafts written by Alcott, Cohen, Becky Johnston, and Philip Levens, and by August 2003, Levens had been replaced by screenwriter Laeta Kalogridis.

Sadly, though, in the last issue of the run, I-Ching was murdered and Wonder Woman was given amnesia. When the Amazons returned her memories (and her powers), they left out her memories of her experiences as just plain "Diana Prince."
I thought George's one "mistake" in rebooting Wonder Woman was making her only 25 years old when she left Paradise Island. I preferred the idea of a Diana who was thousands of years old (as, if I recall correctly, she was in the TV series). From that angle, I would have liked to have seen Diana having been Wonder Woman in WW2, and be returning to our world in the reboot. Not having that option, I took the next best course, and had Hippolyta fill that role.
The New 52 universe does not have a "Diana Prince" identity as stated in an interview by series writer Brian Azzarello. However, when she and Superman began dating, for her civilian identity she used the Diana Prince alias whenever she was around Clark Kent; such as when she introduced herself to Lois Lane at Lois's housewarming party under that name.
