When I search myself carefully I do think it's from my mother. I even feel strange saying that. 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. But certainly influences early on that I felt from my mother. I wouldn't say she was "political" per se; she was sensitive to other people.

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.

I was shooting all this time. And there was only one guy who helped to pull him. And I had to think whether I was going to keep shooting or help the guy. And so I kept shooting and then they put him in this little clinic, and I photographed through the window while they had to amputate his leg. And I felt very strange because I didn't - I felt I could have helped, but I didn't help. But then I also felt elated that I was getting a shot that would be important to the film.

Well, there is a contradiction in a sense. If you're making commercials which sell products which are unhealthy or which are unnecessary, I think that you are part of a system - I am part of a system which encourages people to buy things and do things which are not to their best interest. And to that extent you could say it was contradictory.

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 think that the whole voyeuristic attitude of filmmakers or of me personally - of shooting documentaries and so forth - is an important issue.
