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.

The paintings are not just on flat walls - you have these enormous niches, bulges and protrusions, as well as stalactites and stalagmites. The effect of the three-dimensionality is phenomenal. It's a real drama which the artists of the time understood, and they used it for the drama of their paintings.

I am a product of my failures.

I've never left my culture. I've left my country, but I've not left my culture. In the same way, you shouldn't be worried why George Lucas is going to the outer galaxy to make a movie. He's still making a film within his culture; he's making an American film. I go to Thailand or the Peruvian jungle, the Amazon, and I still make Bavarian films.

I believe the common denominator of the Universe is not harmony, but chaos, hostility and murder.

I'm talking a lot on financing in the Masterclass and I know what it means to because I had to finance my first films, all of them, and I earned my money as a welder in a steel factory doing night shifts while I was still in high school during the day.

Read, read, read, read, read, read, read, read, read, read, read, read, read...if you don't read, you will never be a filmmaker.
