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.

But the question that everyone wanted answered was whether I would have the nerve and the strength to start the whole process from scratch. I said yes; otherwise I would be someone who had no dream left, and without dreams I would not want to live.

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

Of course, you do not do any research: you have to go there and do your film. It's not that I would travel there before without a camera and spend half a year on one of those volcanoes and then come back with a camera. You have to have some sort of a clear mindset.

Netflix knew I was going to North Korea and Ethiopia and Iceland. They saw the film and liked it and that was that.

In the face of the obscene, explicit malice of the jungle, which lacks only dinosaurs as punctuation, I feel like a half-finished, poorly expressed sentence in a cheap novel.

There is a fascination about crime, which is understandable, but hardly anyone talks about the families of victims of violent crime and the devastation that is beyond the victim alone.
