But look at Avatar (2009), one of the most globally viewed pieces of entertainment to have ever been made - the central emotional event of the whole movie was a tree being cut down. And the entire movie, essentially, is saying, "If we let the military industrial complex trash the place that we're living in, we will have committed an epic crime."

The best films of any kind, narrative or documentary, provoke questions.

David Fincher is probably the best comprehensive director in terms of being a manger of a process that must drive forward. He has such confident command of cinema language and visual language and script and performance. He knows more about f-stops than any cameraman, he knows more about lighting than any gaffer, he is a wonderful writer, and he can give you a good line reading. Under pressure, he is the kind of guy who you will just dive in with and trust and follow because his vision is so intense.

When you're working on a creative thing, everyone has an idea, and they're pushing it. The first time you work with anybody, you have to get comfortable with the way another person pushes hard for what they want. Familiarity breeds contempt, people say. But I've found, for creative things, familiarity breeds peace of mind, because you realize you know someone better. You trust each other. You know not to take things a certain way, or a wrong way. You get to where you don't have to waste quite so much time with diplomacy. Things are a little more efficient.

At this point in my life I'm not bent on proving anything, really.

You never make all things for all people and can't always pander to the broadest denominator. I keep an eye toward doing the themes that interest me. Do they move me? Interest me? Make me think? When I run across something that is provocative in an unsettling way, it appeals to me.

I don't think you should sit around and wait for people to give you an opportunity to express yourself or do your work, or whatever. Actors have to be producers and writers have to be producers.
