Life in the oceans must be sheer hell. A vast, merciless hell of permanent and immediate danger. So much of a hell that during evolution some species—including man—crawled, fled onto some small continents of solid land, where the Lessons of Darkness continue.

All of a sudden it's twelve-year-olds who are contacting me, fifteen-year-olds, and they have very, very fascinating questions. However, they speak in a language of their age group which I have to learn first.

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.

I don't see [the jungle] so much erotic. I see it more full of obscenity. It's just - Nature here is vile and base. I wouldn't see anything erotical here. I would see fornication and asphyxiation and choking and fighting for survival and growing and just rotting away. Of course, there's a lot of misery. But it is the same misery that is all around us. The trees here are in misery, and the birds are in misery. I don't think they sing. They just screech in pain.

I couldn't roam wildly and speak secretly with villagers [in North Korea]. No way you could do that. And honestly, I didn't even try. I was realistic of what I could do and yet persuaded them into accepting numerous things that I shouldn't have filmed.

This is the birth of the modern human soul.

It is striking that there is a distant cultural echo that seems to reach all the way down to us, over dozens of millennia.
