I remember the few times that happened to me in writing, where you basically start writing and you look at the clock and six hours have gone by and you're, like, "Whoa! What the hell just happened?" And that piece ends up in the final product even though the final product is three years away. It doesn't get rewritten. It came out the right way. But that's happened to me so few times in my life.

I think it's important as a filmmaker, as any person working in the arts, that you've got to try new stuff and challenge yourself and take chances.

Noah is the battle of justice versus mercy. In Genesis it says that Noah was righteous in his times. You think you sort of know what righteous means, you know, if you listen to a lot of Bob Marley. According to all the biblical scholars we talked to, righteousness is the proper balance of justice and mercy. If you think of that, as a parent, you know that if you have too much justice and you're too strict, you destroy a child. If you have too much mercy, as a parent, you destroy a child as well. A big part of this movie is Noah finding mercy for man.

I'd like to do a lot of different stuff. I think it's important as a creative person to keep challenging yourself and keep doing new stuff. If you end up trying to repeat yourself it's death. It just becomes boring and takes the passion out of it. You gotta find stories and characters that you really want to hang out with.

Right after I did 'The Fountain,' I wanted to go make a documentary or something that was less constructed - more natural. I was searching for a project, and sniffing around, 'The Wrestler' fit right in

I don't think I make genre films. I think studios try to sell films as genres because they know how to do that. There's nothing wrong with that. I don't know what I make. It's sort of a pot roast, all my films.

Classical scores go up and down; they're kind of hysterical in a way. And movie scores are much more - they just drive and move forward, and they build and can't go up and down at that same speed. It's a big job to turn that into something that pushes the movie along.
