I went to volcanoes where I knew that there was a lot of mythology around them; there was something like the creation of gods and monsters and demons.

Some of the most important caves, like Lascaux in the Dordogne region in France, have had to be closed down. There had been too many people allowed in, and they left a mold on the walls that is spreading and which can't really be stopped.

I have made 70 or so films. In all my films not a single actor, a single extra, was hurt. Not one. So statistics are on my side when I say I'm clinically sane.

Well, it had to be about the stories and the people who live under the volcano, what kind of new gods do they create? What sort of demons? And of course North Korea falls clearly into this category since the socialist revolution at the end of the Second World War. Somehow they adopted the myth of the power and dynamics of their volcano.

You should bear in mind that almost all my documentaries are feature films in disguise.

It's funny how in the long time of me working in various countries and various situations that there is this kind of idea out in the media that I am a daredevil and that I risk the lives of everyone around me, but nobody ever gets hurt on my shoot. Some crew members sometimes, but the actors are OK.

We are not accountants, We are not accountants who do number after number after number of storyboard images, a robot could do it ultimately, but what I'm doing a robot cannot do.
