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.

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 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.

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.

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.

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'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.
