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.

There are many dramas that I would like to make: dramas based on real stories. It's approaching things from the other side.

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.

Twenty to thirty years ago, who was making documentary films? Nobody. Well, relatively few people. It was an art form that had limited theatrical distribution, if any at all. Some television distribution, but relatively small audiences regardless. And in the intervening years it's become more and more popular with a lot of people.

The imprimatur of truthfulness does not guarantee truthfulness. People should know better. But they don't.

If you asked me what makes the world go round, I would say self-deception. Self-deception allows us to create a consistent narrative for ourselves that we actually believe. I’m not saying that the truth doesn’t matter. It does. But self-deception is how we survive.

Writing is a form of talking, although writing is such an odd thing in and of itself. People go about it in such different ways.
