Maybe [killers] is one of my real passions. Why deny it?

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.

People like nonfiction presented to them in a certain way, so that they don't have to think about whether it's true or not. They like it to have that imprimatur of respectability, of genuineness.

The first Polaroid ever took of someone in my family was my son when he was about four years old.

All alone - shorn of context, without captions - a photograph is neither true nor false.... For truth, properly considered, is about the relationship between language and the world, not about photographs and the world.

We have more information - a glut of information - than ever before, and perhaps less knowledge. That's what's peculiar. And the only way you can deal with it, I suppose, is to make fun of it. I would rather watch Comedy Central for the news than I'd like to watch any other program on television. Maybe that shows you the state of affairs.

What's great about documentary genre, it seems to me, is that it can be experimental filmmaking. You have a license to do a lot of diverse things under the umbrella of "documentary."
