Leonardo has yet to play a bona fide superhero role -- he usually goes for the sappy romantic leads where he gets to make out with super-hot leading ladies. As of late though, Leo has been taking some roles that involve serious ass-kicking. He beat down the brutal Bill "the butcher" in Gangs of New York, and then in The Departed, he managed to put up a pretty convincing tough guy performance.

The 33 year-old actor has a pretty good record off the screen as well. He produced a documentary about global warming -- The 11th Hour -- encouraging people to combine their powers to destroy global warming. He also through his hat in the green building ring, funding a sustainable hotel in Belize. Leo did draw some criticism with his excessive jet-setting, but as Captain Planet he would no longer require polluting airplanes to wiz around the globe -- only a cape.

I noticed on IMDB that he's also slated to play Teddy Roosevelt in an upcoming film about the life of the conservationist president. Ol' Teddy was a borderline superhero for sure -- and if Leo can pull it off, then Captain Planet will be a cakewalk.
