Tourism is a mortal sin.

I have learned a lot through defeats, and, until today, it's - I'm still haunted by defeats, and they do happen. Sometimes, a film of mine is rejected. And how do you deal with it? And you have to learn how to deal with it and survive anyway.

Ten years ago in Antarctica shooting "Encounters at the End of the World," I met a very fine volcanologist from Cambridge University [Clive Oppenheimer] and we kept talking about doing a film and all of a sudden it became serious when he hinted at the possibility to film in North Korea.

Otherwise [digital revolution] hasn't changed my way of filmmaking, I'm not nostalgic in postulating we should still make films on celluloid. I love celluloid but I don't need to continue on celluloid.

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

If you do not have an absolutely clear vision of something, where you can follow the light to the end of the tunnel, then it doesn't matter whether you're bold or cowardly, or whether you're stupid or intelligent. Doesn't get you anywhere.

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.
