4. Charlize Theron
Charlize Theron definitely has the action background and the diverse set of acting skills to take on the role of Wonder Woman. We have already seen Theron as a superhero in Hancock, and she portrayed a quite convincing invincible woman who knew how to handle herself in battle. Theron would certainly be able to slide right in the star-spangled tights and not seem out of place at all as she is naturally gifted at taking on strong-willed female characters. She proved she could kick even more ass in Aeon Flux, so there is little left to the imagination if she can handle herself in battle alongside the other powerful members of Justice League. Theron also has the attitude and tendency to be very vocal when needed, which adds to the overall quality of Wonder Woman's character. Theron also has shown overwhelming dedication to any role she takes, so research on the character and learning all her traits and weaknesses from the comics and cartoons would certainly be on top of Theron's list as she prepares herself for the role. She is also a very popular actress and adding her name to the Justice League cast list certainly wouldn't hurt things.
