I've had people turn me down. Not all that many, but certainly it happens.

Long, long before I became a filmmaker I was talking to killers. Filmmaking was an after thought.

You can think of my films as cautionary tales, but you might even think of them as despairing tales, because at least in a cautionary tale, you have this idea that by listening to the story you can assure a better outcome. Whereas I'm not at all convinced that's the case. In fact, if anything, I'm convinced that it's the opposite.

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

I actually wanted to publish [ interview with Donald Trump about Citizen Kane] in the New York Times, but the circumstances under which I did that movie made me vulnerable to a lawsuit and at this point in my career, I don't want to go there. But it's amazing.

Tell me what's wrong with this idea: If you're selling to somebody, find someone like that person to sell to them. If you're trying to reach swing voters, if you're trying to reach people on the fence, if you're trying to reach Republicans who are unsure about this candidate... get people who switched! Get people who are registered Republicans. Get people who were George Bush voters who can't bring themselves to do it again. Talk to them, get them to explain what their reasons are, and show them to people. What's wrong with this idea?!

I like to think that I differ from other interviewers in the sense that I hide my agenda more successfully, and I'm more open to hearing stuff that is surprising and unexpected. That I'm actually involved in an investigation, through monologue, at times.
