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

Turning 30 was when my parents both got cancer and were fighting it and beat it, but their mortality started to get to me. Everything wasn't as hunky-dory like it was.

Artist and illustrator R. Crumb did a whole illustration of Genesis. And he didn't go away from the text; he was totally truthful.

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. I've tried to take a chance with every film I've done - I've never done it the easy way, and I think that's because that's what excites me, is making as big a mountain as I can in front of me, and just trying to mount it.

But I think every individual collaborator is different, because they have different brains and emotions and ways of working, so it changes. Definitely.
