There's always that key to every character that lets you go to those places you need to go to. No matter how much you might hate the character, it makes you understand it.

I never heard Coen brothers get defensive, ever. You get with these filmmakers doing the hardest work in the world, and they're not defensive. They're happy together, they crack jokes together, they have different opinions - and it doesn't bother them that they have different opinions. So no wonder their work is so good, because you're getting two for the price of one.

Tone is a very difficult thing. You can't write tone, I don't think. You can try - you certainly try. I write too, so I know I'm trying desperately to communicate to whoever's going to direct my pieces, the way I see the humor. But it's very difficult.

It's Richard Kelly's brilliance, because he led me to Donnie Darko performance. He wanted sincerity, he didn't want it to be one color, and he made me go vulnerable, and I think that's why it works. When you can get all those different colors and levels in one line. Time Out New York voted it "Best Line Of The Year" - which is crazy, because how many words is it? "Sometimes. I. Doubt. Your. Commitment. To. Sparkle. Motion." Eight words. It's crazy.

It was probably 10 at night when I started to read Donnie Darko. I get in bed and read the first page, and I go, "Hmmm. That's interesting." Second page, "Wow." By the fourth page, my heart started to beat, and I knew. It makes me cry, because I knew I had found a classic film. You just know when you get certain material.

I have such a great thing I want to do with Lady Macbeth - make her one of the witches - and I have this whole thing where she's very light and dressed in pink and dancing Gaelic dances and throwing roses, but then when her husband's coming home, she does incantations and pulls her hair back, puts on a black leather trenchcoat. I mean, I could tear it up if somebody would give me the chance! But do you think someone would ever let me do Lady Macbeth? I doubt it. But I'm going to keep talking about it.

I love to take chances. I love first-time directors. I love super-low-budget movies. I've done 80-something movies, and I want to just keep experimenting. First-time directors have new, fresh ideas, and lot of times they're risking a lot to do it, so it means so much to them. They're not just hired; they have their heart on the line, because if you've gone that far, you're probably a very passionate person.
