Here's the thing, with comedy - and I learned this from Will Ferrell - you can't be ashamed. If you're doing comedy, you have to fully commit to the joke. Shame is not part of it. If you act shy or uncomfortable about your body, that makes the audience shy and uncomfortable. And in a comedy you just want them to loosen up and laugh.

The thing I tried to remember when I was younger was 'Do something that's at least as good, if not better, than the last thing you did.' So I started with Brian De Palma and Sean Penn. I had a pretty high bar to start with.

I don't think I could ever stop doing serious movies and just do comedies, or vice versa, but there is something cool about going to work everyday and you're just trying to make your friends laugh. That's nice work if you can get it, you know what I mean? It's different than going to work and knowing that I've gotta slap someone in the face today, and then I've gotta cry, and someone's gonna die, I've gotta get myself to that place.

For a long time, it was like I was part of some special forces unit: I'd land, meet everyone, five minutes later I'd have to do some amazing work, then - boom! - I'm out again. You know, playing supporting parts takes courage.

The truth is, when you're at the track, it was an interesting thing about stock car racing as a sport, is you almost get more out of it watching it on TV.

I do a lot of improvising on movies, actually.

I'm dating myself by saying this, but I was the test audience for 'Space Invaders.' I remember when that was the first game that wasn't a pinball game. I spent a lot of money on 'Space Invaders,' in the form of quarters, of course.
