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 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.

Not one Wall Street executive has been charged with crimes since the 2008 financial crash.

I think that the whole voyeuristic attitude of filmmakers or of me personally - of shooting documentaries and so forth - is an important issue.

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.

Lighting was very primitive. And still it was really the way to learn because sometimes some of the modern technology is so extreme and so compartmentalized that we lose sight of exactly what we're doing.

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.
