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.

I like to find characters. Here's the bottom line: I can't play someone if I can't figure out what he cares about. Everybody cares about something, even a rough character. It defines where we step in life. As soon as you find out what somebody cares about, then it all gets real.

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.

I just loved being around everybody. We just found a rhythm with each other that you want to get on everything you ever do in your life.

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.

It's not like it's not fun to work on big studio pictures. It is. But I can't say that's more fun than working on some little indie for scale. Look at The Amateurs, that's probably the best time I ever had working on a film. With that group of guys, it ended up being an experience I'll never forget. I'll always have the fondest memory of that shoot.

The Underneath was my first film. Steven Soderbergh. I remember that I thought, "Wow, this is such a highlight. Am I ever going to get back to this?" Loved working with Steven and in Austin, Texas, one of the rockin'-est towns in America. I'll always remember it, because I was really grateful that someone finally hired me for a movie.
