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.

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.

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.

My mother let me know that we're all connected. If some of us become more affluent it's not because we're better or even smarter people - we have a responsibility to ourselves to be a good boy.

I had a rope around my waist, and the rope was attached into the helicopter in case I fell off. And the shot was a shot that began with Kim Novak going out of a house and getting into a bus. Then it was supposed to go over the countryside and find a freight train on which Bill Holden was standing. And then after seeing a good look at the freight train, the camera was supposed to move up into the sky for the end credits.

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

I am part of a system which encourages people to buy things and do things which are not to their best interest.
