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.

For example, the face of Nicole Kidman in Queen of the Desert and she is the most beautiful goddess on screen that you can find anywhere around in the world. There's no imperfections, and yet I don't need to know every single pore in her face.

Meanwhile it's got stormy, the tattered fog even thicker, chasing across my path. Three people are sitting in a glassy tourist cafe between clouds and clouds, protected by glass from all sides. Since I don't see any waiters, it crosses my mind that corpses have been sitting there for weeks, statuesque. All this time the cafe has been unattended, for sure. Just how long have they been sitting here, petrified like this?

If you want to propose marriage to your girlfriend and you live in England and she is in Sicily, do the decent thing and walk down there. Travelling by car or aeroplane wouldn't be right at such a moment.

In the Chauvet Cave, there is a painting of a bison embracing the lower part of a naked female body. Why does Pablo Picasso, who had no knowledge of the Chauvet Cave, use exactly the same motif in his series of drawings of the Minotaur and the woman? Very, very strange.

You are in a place that has not been seen for tens of thousands of years, because it was so sealed off. There is such silence that when you hold your breath you can hear your own heartbeat. Everything is so fresh that you have the sensation that the painters have merely retreated deeper into the dark and that they are looking at you.

For me, the distinction between documentaries and feature films is not so clear - my "documentaries" were largely scripted, rehearsed, and repeated, and have a lot of fantasy and concoction in them.
