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."

When people come together too young, they try to become one person. As you get older, you realize that you don't want to become one person because then you lose the person you are.

It's ginned up by the corporate plutocracy as a way of distracting the working-class people that it's screwing. We hamstring our own natural progressivism in this country, and that's really stupid.

But work that's got real substance does make people feel, "There's someone else out there who relates to my experience, or who just helped me understand my own experience a little bit better." And I think that's still got enormous value.

I started, with three friends, this website called Crowdrise that's sort of the Facebook for personal philanthropy, a place where anybody can have a permanent microsite of their own to stage creative fundraising projects for the charities and causes that they care about. And we did it with serious intent but without any ambition.

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 think it's a total fallacy for people to say, "You couldn't make those old movies today." I think there's more ways to get a movie made today than ever in the history of the entertainment industry. It's a very exciting time to work in movies, if you're a creative person looking to make a very personal, weird vision.
