Who would you cast at the titular character?

Will Whedon’s “Wonder Woman” Win-Over Fans?
Can writer/director Joss Whedon’s Wonder Woman break the female superhero box-office curse? reports after a lengthy search for a good story, producer Joel Silverman has given his approval for Whedon’s Wonder script.
“We have a script and we know where we’re going,” says Silverman. “It’s the origin story. It has mythology. Steve Trevor crashes on the island and they go back to Man’s World.”
While the highly-anticipated role has yet to be cast, Silverman hints, “She’ll probably be someone you never saw before, because she’s very young, but I think we’ll have a good time with it.”
Despite the fact that fans rarely show interest in movies about ‘super-women,’ starting from 1984’s Supergirl to more recent sleepers, Catwoman and Elektra, if anyone can pick-up the slack, Whedon can.
