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.

I want the pleasures of the real exploitation movie, and exploitation has changed so much in 40 years. Plenty of people grow up with this fantasy of, "We're going to do it like Roger Corman did it," as that sounds so fun. If you make something small, goofy and exploitative, it's nowhere near the guaranteed moneymaker it might have been 40 years ago. If you look at the way the world works now and money is made, it doesn't seem that fun. Maybe that's just a mental block I have and I need to get over that and find that corner where you can make money and still have a good movie.

I think a lot of people go into filmmaking thinking, "How can I make a career?" And so when they make their first film, they make it thinking, "Well, this'll be the one that gets me to the place where I can make the second film the way I want to make it, and that'll get me to the place where I can make $100 million on the third film." And I thought, "Well, if I put sustainability at the bottom of my priority list, then what opportunities is that going to free me up to pursue?" And that's what I've always done.

I don't want to take shots at professional actors, because obviously the great ones are great. But I do think that given the kind of stories I've been telling in my films, it's hard for me to imagine how professional actors would have done better. And it's easy for me to imagine how they would have done worse. Because I think a lot of what an actor is trained to do and a lot of what an actor's instincts point toward is clarification, is always making it clear what's happening in the story, how the character fits into the scene, what the character wants.

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.

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'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.
