With Superman and Batman in development hell throughout the late 90's and early 2000's, WB tried to branch out to their next most popular character, Wonder Woman, under Joel Silver's supervision.
In 2000, Todd Alcott was hired to write a script, with Sandra Bullock lined-up to star. His draft focused not on Diana Prince, but on Donna Troy, reinvented as Diana's daughter with Steve Trevor. In this version, Diana arrived in Men's World in the 1970's and became a government agent alongside Steve, who eventually became her husband. After Steve's death, Diana sends Donna away to live an ordinary life in Gateway City, but Donna, an introverted secretary, soon uncovers her heroic legacy and helps her mother and rugged police detective Mike Schorr in fighting the nefarious Dr. Psycho. In the end, Diana sacrifices herself to save Mike and ascends into Olympus with the other Wonder Women before her, while Donna inherits her mantle and becomes the new Wonder Woman.
The script was not very well-received and multiple rewrites were commissioned from different authors up until Sandra Bullock dropped out. Unable to secure another A-lister for the role, they scrapped the entire idea and called Laeta Kalogridis for a page-one rewrite.
Her draft was a more conventional adaption of Wonder Woman's origin, with Diana accompanying military pilot Steve Trevor back to Men's World after he crash-lands on Themyscira, only to learn that the god of war, Ares, is engineering World War III in order to take over the world, inspiring Diana to adopt the identity of Wonder Woman to stop him. However, true to the mantra that "Hollywood can fix it", the script adds its bizarre wrinkles, such as Ares being less "cunning warrior" and more "tantrum-throwing asshole" and acting wanting to rape Wonder Woman even though, TWIST, she's his daughter (par the course for an Olympian). Which also makes Diana vulnerable to the Dark Side of the Force AKA "The Rage".
