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.

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.

I think that the whole voyeuristic attitude of filmmakers or of me personally - of shooting documentaries and so forth - is an important issue. And it was an important issue to me, personally. And the whole question of when - when do you put the camera down or when do you keep shooting to get the shot. And a number of times in my life I've had that question hit me very hard.

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 used it in a shot where Richard Burton goes down the hall to get a gun in a closet. And I wanted to get some excitement, and the hallway was too narrow for the dollies that they had at that time. So it was quite useful.

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.

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.
