Absolutely. And as a creepy sycophant in fight club.

Okay, so he mainly does creepy and crazy well lol.

That's only partially a joke, but he did start out doing melodrama on tv, and did well. Did great in requiem for a dream as his first real lead.

He does method and takes it too far, and he really does specialize in roles that are what you might call bat-shit crazy, with a bat-shit crazy movie as an exception in his supporting roles when he plays normal.

But I can't really say he screws up many of the roles. Even the notorious joker turn was in a badly written movie that edited out most of what he did.
