I simply don't like the culture of drugs. I never liked the hippies for it. I think it was a mistake to be all the time stoned and on weed. It didn't look right and it doesn't look right today either and the damage drugs have done to civilizations are too enormous. And besides, I don't need any drug to step out of myself. I don't want them and I do not need them.

We have to articulate ourselves. Otherwise we would be cows in the field.

There are certainly laws and elements that make a film more accessible to mainstream audiences. If you've got Tom Cruise as a strongman, I'm sure it would have larger audiences, but it wouldn't have the same substance.

Ambition is to be the fastest runner on this planet, to be the first on the South Pole, which is a grotesque perversion of ambition. It's an ego trip, and I'm not on an ego trip. I don't have ambitions - I have a vision.

I try to be after something that is deeply reverberating inside of our souls, some deep echo from - even from prehistory. What makes us humans? How do we communicate? Where are we going at this moment? Something for an audience where they can step outside of themselves, where they can be almost like in ecstasy of truth, some sort of deep illumination. And that's what I'm trying in documentaries and in feature films.

At the same time, there's something magnificent about volcanoes; they created the atmosphere that we need for breathing.

If you truly love film, I think the healthiest thing to do is not read books on the subject. I prefer the glossy film magazines with their big color photos and gossip columns, or the National Enquirer. Such vulgarity is healthy and safe.
