According to Moviehole, Teresa Palmer has been offered the role of Wonder Woman in the George Miller Justice League film. This follows the rumor that Rupert Evans will be playing Superman.
Reports have this movie being all action, but with a much younger team of heroes in the early points of their careers. This has made many people wonder why not do a Teen Titans flick, but if you consider more people know Wonder Woman, Flash, Green Lantern, Batman and Superman, than cyborg, Starfire, Raven, Beast Boy, and Robin, then you can kind of see the direction Warner Bros. is going.
Rumors also point to Maxwell Lord, OMACs, and the death of Barry Allen as key points in the story.
