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.

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

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.

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.

When people have problems with their mortgages and jobs many feel they're a failure, they didn't work hard enough or speak well enough: It's their fault things are going so bad. When they see their bodies right there [at occupations], we have something profoundly in common.

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.

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