My films are as much concerned with truth as anything in vérité. Maybe more so.

Certain kinds of intimacy emerge on a phone call that might never occur if you were sitting right next to the other person.

I am profoundly skeptical about our abilities to predict the future in general, and human behavior in particular.

When you start talking about the known knowns and the unknown unknowns, you're thrown into a crazy meta-level discussion. Do I know what I know, do I know what I don't know, do I know what I don't know I don't know. It becomes a strange, Lewis Carroll - like nursery rhyme.

I remember on page one of The New York Times the article about Fred Leuchter. The heading was "Can Capital Punishment Be Humane" and it was the story about an electric chair repairman and execution machine designer. And then buried in the back of the paper was the fact that Fred Leuchter had also been involved in holocaust denial.

I like to think that one of things I've done with non-fiction since the very beginning is to find new ways of telling true stories.

I've never seen myself as a documentary filmmaker. I see myself as a filmmaker, period, and I am interested in drama as well as in documentary.
