You must live life in its very elementary forms. The Mexicans have a very nice word for it: pura vida. It doesn't mean just purity of life, but the raw, stark-naked quality of life. And that's what makes young people more into a filmmaker than academia.

The elections have a different platform, the town hall is the platform for it. But the other question behind all this is should I run for president?

It is not only my dreams, my belief is that all these dreams are yours as well. The only distinction between me and you is that I can articulate them. And that is what poetry or painting or literature or filmmaking is all about... and it is my duty because this might be the inner chronicle of what we are. We have to articulate ourselves, otherwise we would be cows in the field.

We were very, very lucky [with Tim White filmed making historic discoveries in the East African Rift ] . In 100 years, only three skeletal remains [of early man] were ever found at this site. This was the third one, and we were right there when it happened. In fact, when I first heard they had found something, I said, "Please stop it! Don't do anything right now. Let's do it tomorrow until we have unpacked our cameras and assembled our stuff.

I am torn between the beauty of the natural world, which you see all around us, and the idea that some dumb tornado could blow a telephone pole onto my sweet Camaro.

Everything that I've done was prudent and never has anyone gotten hurt in my films - not a single actor, not a single extra, ever.

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.
