Writing a story starts out as a puzzle in your mind, of "What is it I'm fantasizing about right now that makes me think this is going to be worth years of work?" And you just keep pushing and trying to figure it out, and once you've hit on these resonances... Then as a screenwriter, it can be dangerous if you get too hooked on just finding things that resonate with each other, because then you risk getting into stuff that's too neat, and becomes stifled as storytelling. But you do feel like you're on the right track when you start to have a sense of what goes with what.

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.

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.

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.

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.

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.
