I'd base the Film more or less on the Wonder Woman Direct-To-Video movie.
Casting:
Jordana Brewster as Wonder Woman =
I Think she could play the character well.
Carla Gugino as Hippolyta =
I loved her performance in Watchmen and I think she's good for the role.
Bradley Cooper as Steve Trevor =
If they make Steve how he is in the direct-to-video movie,than he is perfect.
Jessica Biel as Etta Candy =
Yeah I know, "She's better for WW" but I really dont see her for WW so I rather have her as Etta.
Gerald Butler as Ares =
If he uses his 300 voice I think he could make it work.
Isla Fisher as Circe =
Circe can be a follower of Ares,I was originally going to go with Amy Adams but her voice is too "soft".
Mariana Klaveno as The Cheetah (Barbara Ann Minerva) =
Circe can change her into The Cheetah.
Based on her performance in True-Blood,as ill's maker,I think she would be perfect for character.
Rachel Nichols as Artemis of Bana-Mighdall =
She has the look, and so far in the trailers for GI:Joe she aint that bad actress.
Thats That.
