I'm not into digital marketing, downloading, or streaming - I've always been a man of the theaters.

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

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.

Hold firm to your vision but don't be a tyrant on set.

For example, how you would introduce a leading character into your film, and as an absolute ingenious example, [Elia] Kazan in his film Viva Zapata!, how he introduces his leading character Marlon Brando into the film. No film ever did it as wonderful as he did it.

When I film, there are no emotions. That would be the last thing.

For a film I shot on the most difficult mountain on God's wide earth in Patagonia for a sequence where there was high probability some digital effects were needed, somebody made storyboards and I quickly ignored them, after half an hour I ignored them and I never used any digital effect.
