We were very, very lucky [with Tim White filmed making historic discoveries in the East African Rift ] . In 100 years, only three skeletal remains [of early man] were ever found at this site. This was the third one, and we were right there when it happened. In fact, when I first heard they had found something, I said, "Please stop it! Don't do anything right now. Let's do it tomorrow until we have unpacked our cameras and assembled our stuff.

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 do have a clear vision, and I do see things that are existing in my quote-unquote spirit, but that doesn't necessary make me a very spiritual person.

I'm not a one-trick horse.

For me, the distinction between documentaries and feature films is not so clear - my "documentaries" were largely scripted, rehearsed, and repeated, and have a lot of fantasy and concoction in them.

I doubt that VR will really replace the quality of books. If you want to go into let's say the Prado in Madrid and you want to go into Hieronymus Bosch or whatever, you'd rather go into books and you take your time and it's sitting there all day long and you go back and revisit it and it becomes part of your physical life.

In my films, I hope there are a few moments where you feel almost illuminated, like in a state of ecstasy, stepping out of yourself, beyond yourself and perceiving something which is only, in the case of cinema, possible in collective dreams.
