There was no actually stock footage in "Medium Cool." I wrote the script. I wrote the riots. And I integrated the actors in the film in the park during the demonstrations. But nowhere was it like we had stock footage and then later, in editing, integrated it into the film. It was all done at the time.

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.

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.

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.

There is a very particular feeling I get when I have the camera in my hand, looking at an actor talk, knowing that what I’m shooting will end up on the screen.

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 think that it gave me a really strong feeling of my life force and a confidence in myself. I felt like I was a man. Before that point for some reason, I always felt I was a boy (laughter). In fact, they called me the baby on the ship 'cause I was the youngest guy on the ship. But I always felt that way.
