If you're making commercials which sell products which are unhealthy or which are unnecessary, I think that you are part of a system.

The idea of accountability in Vietnam, Nicaragua and now Iraq - the media never has that in its quiver. When you see time after time there is no possibility of Nuremberg [war crime trials], we're doomed to have it repeated.

Most people, I believe, when they're asked profound questions about their own persona are not really able to enunciate it, because it's a combination of so many things.

I think that the whole voyeuristic attitude of filmmakers or of me personally - of shooting documentaries and so forth - is an important issue. And it was an important issue to me, personally. And the whole question of when - when do you put the camera down or when do you keep shooting to get the shot. And a number of times in my life I've had that question hit me very hard.

I had a rope around my waist, and the rope was attached into the helicopter in case I fell off. And the shot was a shot that began with Kim Novak going out of a house and getting into a bus. Then it was supposed to go over the countryside and find a freight train on which Bill Holden was standing. And then after seeing a good look at the freight train, the camera was supposed to move up into the sky for the end credits.

My mother let me know that we're all connected. If some of us become more affluent it's not because we're better or even smarter people - we have a responsibility to ourselves to be a good boy.

I rationalize out, well, how much help could you really be, you know? And maybe if people saw this, they'd realize the brutality of war and figure out there's got to be some better way than killing human beings who are just trying to farm a field.
