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.

Robert DeNiro, who may be the greatest living actor, usually acts in a way which is very stone-faced, like Steve McQueen. For example, Steve McQueen, if you cut the sound, you don't know what he's acting really. He gives to the lines, to the text, something very special, and he's very good. He was a great actor. But, to do a silent movie, you have to have more expressive actors.

Sometimes I think you have to try to do things that people don't think are doable. I remember at the very beginning actually, the first person I had to convince was myself really because there's a self-censorship. When everybody says 'we don't do silent movies anymore,' you agree with everybody, and you say 'yeah, you're right.' It was a fantasy.

This is the problem with language, and this is what makes silent movies fun, because the connection with them, me or the audience is not with the language. There's no question of interpretation of what we are saying it's just about feeling. You create your own story

It's about storytelling. The story is told through images. So with the cast, I had to make sure that the emotions were readable without sound... I know some great actors, if you turn off the sound, you don't really know what they're saying

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 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.
