There are two aspects to making movies: One is the feeling of wanting to push myself into stuff that I don't know how to do. Then there's the other impulse to try and earn a living. I want to be careful about not confusing those too much - not that those things can't have a healthy overlap. Plenty of people start out making work that isn't terribly commercial, and then make work that's more commercial but still good. You just want to watch out for that thing where you tell yourself that you're doing your best work when you're not.

There's nothing sillier than fake rough edges, like the handheld camera you sometimes see on "NYPD Blue," shaking and jittering around, unmotivated, way more than any actual documentary camera would.

I'd love to do a really cheap action movie. I'd love to do stunts. I mean, not myself. I'd hurt myself, but I'd love to direct others doing stunts. I think that would be a blast. The funny thing is, if I really think through this fantasy, I know that the way I conceive of doing an action movie would still lose money. No matter how far I think I'm getting away from myself, it always comes back to something that's not terribly commercial.

I've always spent a lot of time in movie theaters, kind of absorbing anything I can. I just love sitting in the dark, and watching the flickering image up there. Just sitting in a movie theater alone is inspiring to me. It takes a pretty bad movie to drain the magic out of that - but Lord knows, those movies exist.

Sometimes you meet someone, and they seem great, they seem exactly what you're thinking of for the role, and then you put a camera on them, and they freeze. And other people come to life with the camera on them. I haven't discovered any reliable predictor for that; I think you just have to try it and see what happens. And, you know, sometimes the people who freeze, if you find the right magic word to say to them, you can unlock them.

It's always a struggle with small films to get people in the theater. I think I have a perverse contrarian streak that's always kind of aspired to make movies that are impossible to market.

What will always be possible is for someone to walk into a dark room and experience a film and connect to it. And that's why I make my films - for people to go and have that experience. That's really the whole dream for me, so that hasn't gone anywhere. What has gone somewhere is making the numbers add up on each side of it. And who knows? I've had all kinds of freak-outs. I got married recently, and my wife listened to me go off the other day on this fear that maybe our culture has just moved beyond art entirely. Maybe we don't need it anymore.
