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

I felt that that experience, because of the responsible nature that I found I acted all during that traumatic time, that I felt that I was a man.

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.

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

When I started, we had just the camera and the person, mostly. And if you wanted to do a dolly shot, particularly working in Chicago where I began, you'd get in the back trunk of a car, and you'd have a friend drive the car, or you'd get in some kid's little wagon that he plays with and have someone pull that for dolly shots.

In "Virginia Woolf" I had a thing which the grips called the paraplegic which was a wheelchair thing that I had made up years before where I could stand on this bicycle-like device and be pushed down the hall, and then step off it with a handheld camera.
