If you go to Florence, it has all surface beauty, but like Venice, it's simply a museum of Renaissance times. Los Angeles is raw, uncouth and bizarre, but it's a place of substance. It has more new horizons than any other place.

It's not because nature is angry, it's rather that we are stupid. We're not doing the right thing with our planet.

When I say tourism is sin and traveling on foot is virtue, it's condensed into a dictum. It's much more complex than that, but let's face it, for me, my experience, the world reveals itself to those that travel on foot. You understand the world in a much deeper level. And it does good to anyone who makes film.

If you don't read, you will never be a filmmaker.

Film is not the art of scholars, but of illiterates.

This is the birth of the modern human soul. The artists are like us, not like the Neanderthals, who had no culture - and who incidentally were still roaming the landscape at the time the paintings were made. It is striking that there is a distant cultural echo that seems to reach all the way down to us, over dozens of millennia.

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.
