From my image of digging around in the mud like a grunt, I preferred fighting the war from ships.

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.

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.

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.

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.

When you hear the word tear gas you think, well, your eyes will burn and that's it. But that whole feeling of your whole skin burning, that you can't breathe, you can't inhale, you feel suffocated - it's a very, very terrifying experience.

Well, of course the general idea was dreamed up by the advertising agency and so my job was to realize that. And we down to Lubbock, Texas, usually and onto a ranch and we would pick cowboys who looked the part and photograph them under dramatic situations - rounding up wild horses or running through streams and then reaching in and taking a drag on a cigarette.
