Who would be a good actor to play Holden Caulfield from 'The Cather in the Rye'?

Kieran Culkin played a guy named Igby in the movie Igby Goes Down. People often say that Igby Goes Down is supposed to be a very similar version of The Catcher in the Rye (it's not a movie adaptation. it just contains many similarities to CITR). Kieran Culkin seriously seems like a real Holden Caulfield. I luv luv luv him lol. Even in interviews, I could just imagine him as Holden Caulfield.
