With Edward Norton you'd never say, "This is the one we're going with whether you like it or not." It has to be agreed upon.

I do subscribe to the maxim that generally comedy is like jazz. Either you get it or you don't. You can't learn it and you can't be taught it. I don't think that if you are not a funny person, you can fake it.

Duality is not a story. Duality is just a complexity.

To me, Fight Club was a comedy. When [David] Fincher sent me the book and I read it, the first thing I asked him was, "This is a comedy, right?" he said, "Yeah, that's the whole point," and I said, "Okay, I'm in." I certainly wasn't imagining myself as a dramatic actor when I was running around in my underwear in that film.

I've always liked the idea of taking old dramatic ideas and devices and making them feel relevant or contemporary or whatever.

I had a huge advantage with Edward Norton because he's directed a movie before, so one thing he appreciates is how hard my job is, he's very sensitive to that. We actually ended up finishing "Leaves of Grass" a day early.

I don't get much out of doing a red carpet.
