I don't want to travel.

Some of the most important caves, like Lascaux in the Dordogne region in France, have had to be closed down. There had been too many people allowed in, and they left a mold on the walls that is spreading and which can't really be stopped.

I don't dabble, I'm good at acting.

Strangely enough, there's this mythology sprouting out that I cannot stop.

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.

I'm reminded of an interview Larry King had on his talk show with one of Michael Jackson's sisters. He's talking about how many millions she made on her latest record, and all of a sudden, she looks at him tearfully and says, "Larry, you know, I'm not interested in money or sales or songs. I'm a spiritual person." And I thought, "Oh my god..."

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