Our presence on this planet does not seem to be sustainable. Our technical civilization makes up particularly vulnerable. There is talk all over the scientific community about climate change. Many of them [scientists] agree, the end of human life on earth is assured.

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.

There are photos of Kim Jong-un right up atop the volcano. I actually wrote a letter to him asking if I could speak on camera. I never got an answer. But what was interesting was the people who were responsible for us, our "guards," it took them two days to figure out how I should address him. "President? No, you can't because there's a president for eternity." And it was a time when his status was still in flux. Only a few months later there was this party congress which assigned an official title to him, but that was after we did our film.

I don't spend sleepless nights over getting very bad reviews.

There is never an excuse not to finish a film.

Similar thing until today, with digital cameras you look after something like that as robust as they can be.

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.
