Once you click into a character, to a certain degree, you can do a lot else. You can do other stuff, then come back and click right into the character. It's sort of funny that way, the way the mind works. Once it's there, it's sort of there. For the stage, for example, all through the day, you're not onstage. You're living your life, la-la-la, then the lights go down, then boom! All of a sudden, you're in this thing. There's a kind of reflex muscle trigger that happens, and all of a sudden you're back into the role. It's just getting there in the first place that's tricky.

Certainly what constitutes a stage actor, what constitutes a film actor, I don't even know what that is. And both things are very accurate, in a sense. In terms of people's needs to concentrate on race, I wonder if it's completely necessary, but it's not something that is so dynamically relevant to me that I feel it should be one thing or another.

David Mamet was great to work with. He was everything that I thought he would be as a director. He's incredibly articulate, an easy collaborator. Extraordinarily knowledgeable about film and writing.

I believe people instinctively know that about writing, yet people get confused about that when it comes to acting.

I was already devouring literature and I was the ripe old age of 15 when I decided to be an actor. I just thought plays were the most fantastic way of expressing life. I thought I'd discovered Shakespeare - 'hey, there's a new guy in town, don't know if anyone's read him.' I was just excited about the whole thing, from day one.

I would love to be a fly on the wall watching other directors and actors to see what their process is like.

I was always lucky that I've always had a gig, I'm fortunate in that way.
