If you want to propose marriage to your girlfriend and you live in England and she is in Sicily, do the decent thing and walk down there. Travelling by car or aeroplane wouldn't be right at such a moment.

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.

That shot in "Into the Inferno" somehow popped up while my editor and I were viewing the footage. I immediately said, "That looks like the opening shot because the camera approaches the action very slowly and we have enough time to insert some of the main credits into it." So it was a practical choice. At the same time, you see these tiny figures standing at the rim of something, and all of a sudden, the camera rises further and you find yourself looking straight down into an inferno.

You also can understand how to play tennis from Serena Williams, and she is awesome. I haven't seen her Masterclass but just watching her on the court - I saw some of Wimbledon on TV and there's such an awesome force in her and focus and determination and technique, you just look at her and it's awesome. If I would like to learn tennis I would immediately turn to her.

I was able to persuade them to let me shoot in areas that were beyond the volcano itself. Beyond the joint scientific program between Cambridge University and North Korean scientists. I was able to film in a kindergarten, subway, other things you would not normally be allowed to do.
