North Korea is not an exception. Even there, where you think it would be completely sober, they have the myth of their revolution being connected to the volcano.

I am somebody who creates images, with my perspectives, fascinations and my instincts as a narrator. You have to activate the audience's imagination. If you are just giving them scientific results, they would forget the film in five minutes flat.

It happens sometimes that the material itself carries things you have not fully planned. The footage has its own right, its own life, its own vibrancy and energy in it.

It's not far-fetched that almost everywhere in the world where you have volcanoes you have mythologies or new gods being created.

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.

I try to be after something that is deeply reverberating inside of our souls, some deep echo from - even from prehistory. What makes us humans? How do we communicate? Where are we going at this moment? Something for an audience where they can step outside of themselves, where they can be almost like in ecstasy of truth, some sort of deep illumination. And that's what I'm trying in documentaries and in feature films.

It's curiosity, and always a sense of poetry. You see it in particular in the chapter "Iceland" where I'm reciting ancient Icelandic poetry. It has this very beautiful gravitas in conjunction with the volcanoes.
