But sometimes I think you have to try to do things that people don't think are doable.

The Germans were much more graphical. The expressionism is much more than cinema. It was a movement with artists, painters, music and architecture, so it's really graphic and visual. And the French were something else.

I think Hollywood is cleverer than you think. I'm not sure they will do it. I don't think so, but maybe I'm wrong. When we were doing the preparation of the movie, we didn't have all the money so we were looking for all the solutions possible, and 3D was one option.

I like to shoot beautiful things. My two previous movies were one in the '60s, the other one in the '50s, and this one is in the '20s. This is a period that's very cinegenic. The cars, the props, the suits, the haircuts, the dresses, everything, and it gives you pleasure to compose frames with that material. The music, I really love jazz, so for me, when you have good materials and nice things, it's very pleasant.

Finally, you're right about one point, your entire way of thinking is predicted by what you're immersed in so you know you won't make a bad decision. You can make a bad decision but it's still in the good sphere normally if you work well. You're prepared to face a crew who wants to know everything and poses a hundred questions a minute, because you know you have good reflexes and can respond very quickly.

I love silent cinema but don't hold it sacred. Like any branch of film there are some very boring films alongside the masterpieces.

I chose the American ones, more or less the last five years of the silent era, because those are the ones that aged the best in the way they tell the story. One, it's about human beings with context. It's a very classical story with feelings, with laughter, melodrama and it really works, the good ones - Murnau's American movies, John Ford's Four Sons, King Vidor's The Crowd, or the (Josef) von Sternberg movies. You can watch it now and it still works. I mean they are really, really good pieces so this is where I tried to work.
