The deal was we had to have people accompanying us and they would ask us not to film something [in North Korea]. For example, we wanted to film at a certain place and there happened to be a building under construction and it didn't look as fancy as the other buildings, so they wanted us to shoot where everything looked finished and made a good impression of the cityscape.

I was able to persuade them to let me shoot in areas that were beyond the volcano itself. Beyond the joint scientific program between Cambridge University and North Korean scientists. I was able to film in a kindergarten, subway, other things you would not normally be allowed to do.

When I see a face, I see a face in general and I see you are curious, I see the curiosity but I don't not look after a dermatological report of your cheeks, and that's what you see when you're too high-resolution. And now desperately in post-production, in color grading, they are trying to wipe out the precision of the dermatological report.

North Korea has a very striking mythology there. It is influencing the whole nation.

I am a product of my failures.

I function better in the jungle in Amazonia or Antarctica or Alaska or the Sahara desert. An artificial environment like a studio has never attracted me. I could work in a studio, but I would never really feel at home.

Well they are very frightening for me because their stupidity is so flat. You look into the eyes of a chicken and you lose yourself in a completely flat, frightening stupidity. They are like a great metaphor for me... I kind of love chicken, but they frighten me more than any other animal.
