Of course the entire planet Earth consists of magma under us, and only the very inner-core is different.

Our presence on this planet does not seem to be sustainable. Our technical civilization makes up particularly vulnerable. There is talk all over the scientific community about climate change. Many of them [scientists] agree, the end of human life on earth is assured.

Fragility of modern world leaves me with the idea we'd better anticipate what's going on. We take our right steps today and now. And we'd better avoid, that we are overdependent on, let's say, the internet.

I always had a feeling, for example, that there should be something from Verdi's "Requiem" in the film. You hear it when you see the lava flow in Iceland. That turned out to be a very easy choice.

In a way, I managed to get the deepest things, the best things out of people. That's why I'm a filmmaker. If you don't have it in you, you'd better do something else.

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.

I have a great map of the Tibesti Mountains in the southern Sahara or Northern Chad. It's a dream of mine to go there, but it's such a volatile area, you have to be prudent.
