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.

You have to be very prudent with what you are doing and what sort of tools you are utilizing. Drones have become a wonderful new tool in filmmaking.

Facts do not convey truth. That's a mistake. Facts create norms, but truth creates illumination.

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.

Netflix knew I was going to North Korea and Ethiopia and Iceland. They saw the film and liked it and that was that.

This climate surrounding me has reached Clive Oppenheimer. In practical terms he sees that I'm not interested in any sort of daredevil stunts, I'm just interested in the work. And he's convinced that I'm clinically sane.

I don't spend sleepless nights over getting very bad reviews.
