The helicopter was a U.S. Navy helicopter. There were no civilian helicopters available to film companies, so they just made some stuff out of two-by-four wood. And I would straddle a two-by-four out from the helicopter with a camera and what we call a high hat, which is a low metal stand.

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.

We, as film-makers, are privileged. We can make people cry or laugh. We can make them think and feel. It is a great privilege and a great responsibility.

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.

That force - which the system tried to laugh at - when it finally broke through and the movement was recognized, the media said they were "just a bunch of spoiled kids, dope smokers [who] don't know what the hell they want." To demean it as something laughable - but that didn't work for very long. It's still an ongoing struggle; they're trying to find out how to fight. It's very exciting times.

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.
