You do realize Kevin Spacey played him in the last film. I could definitely see Leo pulling that off, I just don't know that he'd accept. Its always a big step in an actor's career to play a villain for the first time.
You're right about that. Waltz was right up there with Heath as the joker...I'm curious to see what he does with his next villain in Water for Elephants...the pics from the set are pretty interesting, he has a real swagger when he walks as opposed to Landa who's like a nerd lol
