There are certainly laws and elements that make a film more accessible to mainstream audiences. If you've got Tom Cruise as a strongman, I'm sure it would have larger audiences, but it wouldn't have the same substance.

I have nothing against 3D films but I do not need to see them.

I wouldn't like to travel at all. I've been too much around.

I must say, the people who started this whole Masterclass series have been very helpful and very intelligent to point out certain things and also give me some guidance, "isn't there something missing, shouldn't we address this or that?" so it's not completely alone out of the blue. It's very well thought through.

Clive [Oppenheimer] and I figured out that I'm the only one probably in the film industry who is clinically sane. I say that as a joke, but there's a grain of truth to it. I'm not a stupid daredevil who jumps into the crater of the volcano to get the closest close-up, I'm not one of those. And you have to be aware that you have a crew with you and you are responsible.

I have been in lots of very intense life situations. I have been shot at, and I have been hungry, and I have been in solitude, and I have also briefly been behind bars. So in a way, I know the heart of men.

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.
