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."

This place [USA] is exploding with young people who are - they're like Nietzsche's hammer - going to break everything and make something better. The creative energy in this country, and what people are coming up with is very hopeful.

You can do things in twin scenes now you couldn't before. You can implement actual moving cameras.

The thing I'm absolutely convinced of, no matter how crazy - technological the world is getting, is that people feel more connected through the good works. Entertainment, and the sort of soporific effect it has on people and their stress, is one thing.

Everyone thinks that Fight Club is a very important and successful film, but it was a massive box-office failure. Massive. It was a big flop by any commercial-release standard. And it's been a huge hit on DVD. Everything that movie has become has been on DVD. So you can't stake your sense of creative success on this whole box-office-performance matrix, because if you do, you're going to be disappointed most of the time.

Instead of telling the world what you're eating for breakfast, you can use social networking to do something that's meaningful.

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.
