I've never done anything that I felt was crossing the line for me. But everybody has to make that decision individually. Like, I've never shot heroin to play a heroin addict. I've never turned a trick to play a prostitute. Whatever. You draw the line where you feel it could be harmful.

You try to find the internal life, but a lot of it is creating it through physical behavior and figuring out the voice when you create as much of a past as you would in a naturalistic piece. But it's fun, because it's like you're learning something, learning some kind of physical skill.

Writing, producing and directing, I must say, is incredibly satisfying and gratifying.

Sometimes the work can get in the way and you give a less-good performance, and sometimes it doesn't and you can really get to the heart of something. And all the other stuff is just interesting and adds another layer to your performance. It helps you find the reality. Because you're not just playing yourself, you know? That would be kind of boring.

I hope my talent has something to do with it. I just think this business is so crazy. I obviously do the best I can, and the directors I admire see something in me. But this is a strange business, and there are people who are incredibly talented who never make it, who never get these opportunities. So that's why I say I'm lucky. I don't feel that I'm not talented - I think I am talented - but I also think I'm very lucky.

One of the reasons that I do a lot of different kinds of pictures is because I learn a lot when I'm doing them.

I just don't plan things. I live a month at a time.
