Even my wife and two of my children are in "Leaves of Grass". Because I love the source material so much, it was really easy to write and an utter delight to get to direct because I had people like Edward [Norton] elevating the material and surprising me in their interpretations of all of this stuff that's so close to me.

When I look at the directors that I really love, who really develop their films over time, they're almost always the ones who go back again and again and again at the same investigations. I think that when somebody has a theme they go after, it's fun to service that. It's like, "I know you now. I know what you go at." It helps you locate yourself a little bit quicker in their world.

Basically, I think 21st century conservation is moving toward preserving ecosystems by dealing with the needs of people.

In a very philosophic sense I think doing the work is itself a good thing. But at the end of the day, since we're taking other people's shekels to do it, and their work is being able to make a return out of it, it forces you to consider the fact that you're doing it for other people. The whole construct is built around the assumption that it's going to get shared, and that someone else is going to find value in it - entertainment, catharsis, enlightenment, or whatever.

I do find myself drawn more to pieces that I feel are wrestling with the way that we're living now, what we're all going through.

I start to get fixated on a story and a character and an idea, and at a certain point, I really want to do it. It's a compulsion to explore a specific thing, as opposed to a compulsion to direct, generally speaking.

It's better for people to miss you than to have seen too much of you.
