My contacts with the film industry can be described in very simple terms: The industry does not really need me, and I do not really need the industry.

Martin Luther was asked, what would you do if tomorrow the world would come to an end, and he said, 'I would plant an apple tree today.' This is a real good answer. I would start shooting a movie.

You have to be completely open to what people would tell you. You do not shape them; you do not force the materials into your ideas. You have to have all windows and doors open.

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.

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.

We have to articulate ourselves. Otherwise we would be cows in the field.

When I say tourism is sin and traveling on foot is virtue, it's condensed into a dictum. It's much more complex than that, but let's face it, for me, my experience, the world reveals itself to those that travel on foot. You understand the world in a much deeper level. And it does good to anyone who makes film.
