I did a small, small thing in Quiz Show, where I was really just a glorified extra. But, you know, New York actor, few days on a film set: Great! I was probably making subway fare on the play that I was doing at the time. I always think of The Underneath as the first film that I ever did.

I like characters where there's something going on and something to make him real. If you find out what somebody cares about, all of a sudden, the whole world opens up.

The greatest joy in getting ready for the film is that there aren't many reference points for the journey and you've got to define it for yourself.

Go is one of my favorite things that I ever did. Not that I critique myself, but sometimes I'll be passing by the television, and I'll say, "Meh, maybe I would have done that a little different." I can't help [but] do that. But Go was one of those things - I really loved working with Doug Liman. Detective Burke in Go is one of those roles that's about everything I like to do. I love parts like that. And Go seems to be the thing that rolled it all into one.

I think that there's no doubt that to work in film is a bit more of a creative journey. It's not that I don't put the same time or heart into something that's on television.

Whether it's one scene or 15 scenes in a film, whether it's the lead or a cameo part, if I don't find it interesting, I tend not to do it. You never really know what it is. It could be a one-scene part. I remember I read the one scene in Crash and was asked to do it. I was like, "Absolutely!" There's no formula for how something has to be. I always try to keep it that way.

When I was younger, I never wanted to rehearse because I thought that someone would figure out I don't know what I'm doing.
