I'm an actor, and, beyond that, the thing I do most compulsively is writing. So I come at it very much from this sense of character. I get interested in people. And I feel confident in my capacity to absorb and manifest the characteristics of people. I have a real auditory hang-up for dialogue; re-creating the way people talk really is an addiction in my brain.

To me, achieving tone, achieving consistency, is exactly the job of a director. It is to be the fusing, the nexus of a whole bunch of people contributing to the complex life of a movie. There are actors, there's a cinematographer, there're costume people, set people, there are all these things, and you somehow have to be the person in the middle of it who is making it all synchronize into the same magic bubble.

I read a lot of scripts and so many are clearly a knockoff of one familiar genre or another.

What we set out to do with this movie [Leaves of Grass] was to create something that was funny and serious and had large tonal ambitions. A movie that could be poignant and funny, and suddenly quite violent. To have a character utterly sideswiped, and to learn that life is about balance.

I don't flatter myself - I'm not a scientist, I'm not a conservation expert.

The Zionist Tulsa Jew who's pugnacious is a reality. I grew up around it. And I think it's really, really funny and surprising and unlikely.

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.
