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

When I film, there are no emotions. That would be the last thing.

Most of the volcanoes are pretty far away. You have to go to, God knows, Alaska. Or you have to go to the Southern Indies or you have to go to a specific island.

It has always been my aim to find that sort of passion and figure out how to transform it into cinema.Timothy Treadwell's footage was almost like a diary, and he had always dreamt of becoming the movie star in his own gigantic production.

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.

My non-fiction films are pretty much fiction, or at least close... It's all "movies" for me. I never have searched for a subject. They always just come along. They never come by way of decision-making. They just haunt me. I can't get rid of them. I did not invite them.

If you do not have an absolutely clear vision of something, where you can follow the light to the end of the tunnel, then it doesn't matter whether you're bold or cowardly, or whether you're stupid or intelligent. Doesn't get you anywhere.
