I couldn't roam wildly and speak secretly with villagers [in North Korea]. No way you could do that. And honestly, I didn't even try. I was realistic of what I could do and yet persuaded them into accepting numerous things that I shouldn't have filmed.

Everything that I've done was prudent and never has anyone gotten hurt in my films - not a single actor, not a single extra, ever.

Of course I do things in my voice in my commentary, which I wrote.

I prefer to be alive, so I'm cautious about taking risks.

The world reveals itself to those who travel on foot.

Spirit of immersion and curiosity and awe and participation is something which Timothy Treadwell and I have in common.

We do not see the danger clearly enough that we develop images adequate to our state of civilization. When you watch TV, you know instantly that there's something wrong with the images. When you open a magazine and see the ads, you know there's something wrong with the images. And it's unhealthy and not good and outright dangerous, in my opinion.
