When BATMAN BEGINS became a hit with both critics and audiences, it inspired WB to start taking their DC Comics properties seriously, starting with Wonder Woman. They scrapped Kalogridis' draft and decided to give the project a major overhaul, and called Joss Whedon for writing and directing duties in 2005.
Whedon's pitch centered on Diana accompanying Steve Trevor to Men's World on a diplomatic mission, only to learn it is filled with violence, poverty and corruption. She adopts the identity of Wonder Woman to bring justice to crime-ridden Gateway City, and learns that the culprint is Spearhead, a weapons manufacturing corporation whose CEO, Aaron Buchanan, is actually Ares in disguise, feeding off of the havoc he's wreaking. When Ares finds out Diana is interfering with his business, he deploys his cybernetically-enhanced nephew, Strife, to kill her.
Whedon submitted multiple revisions from 2005 to 2007, but could never reach a consensus with WB in regards to the tone and the story. Despite this, WB met with numerous actress to take on the lead role, among them Sarah Michelle Geller, Charisma Carpenter, Taylor Cole, Lake Bell, Katherine McPhee, Jill Wagner, Sophia Bush, Rachel Bilson, Eliza Dushku, Nadia Bjorlin, Rhona Mitra, Priyanka Chopra, Evangeline Lily, Katie Holmes and Megan Fox. Whedon's top choices, however, were reportedly Morena Baccarin and Shannyn Sossamon.
