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.

When I was in Vietnam with Jane Fonda, I was shooting a farmer in a field - just a pastoral scene. And while I was shooting him, an explosion occurred right - he blew up right in my lens, so to speak. And he had stepped on a landmine.

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

When people have problems with their mortgages and jobs many feel they're a failure, they didn't work hard enough or speak well enough: It's their fault things are going so bad. When they see their bodies right there [at occupations], we have something profoundly in common.

I'd say to anyone trying to break into the business: Don't just be interested in movies. Be interested in life. Be a person. Be in touch.

When I started, we had just the camera and the person, mostly. And if you wanted to do a dolly shot, particularly working in Chicago where I began, you'd get in the back trunk of a car, and you'd have a friend drive the car, or you'd get in some kid's little wagon that he plays with and have someone pull that for dolly shots.

I've been in wars and in riots and hung out of many helicopters in the early days. And there's a detachment that happens when you look through the camera. You're looking for the shot.
