It's very enigmatic because of course, the population [of North Korea] has no contact with the world outside or it's very, very limited. They don't have any telephone connections, no radio, no TV, no movies, no newspapers - nothing from the outside world. This is very strange and there's the very strict, unifying government that forces you to be in step.

Let's do it tomorrow until we have unpacked our cameras and assembled our stuff.

I never planned my career in steps. It's all coming at me like burglars in the night.
