Read about this on movies.com, concerning the Wolverine movie.
Gerard Butler (Leonidas) is going to play Creed, who becomes SABERTOOTH. Gerard Butler = Sabertooth? Yes.
And apparently, they're trying to get Ryan Reynolds to play Deadpool. YES.
BUT. Movies.com has described Deadpool as "a slightly cracked mercenary who uses plastic surgery to create new identities." Hm. I don't know much about Deadpool, but I never heard of the plastic surgery thing. I know him as the scarred up motherfucker that's sadistic and funny as hell.
So, yeah. Leonidas is Creed, and Ryan Reynolds is "Deadpool." We shall watch this with great interest.
