When you look at the early-'30s movies, like King Kong, the codes of acting are very similar to those of silent movies. In some of the silent movies - the good ones, the ones done by the best directors - the acting is very, very natural

If you try to make a silent movie with a normal script and you just pull out the dialogue, you will have big problems with the actors because you will ask them to tell a story that you don't know.

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.

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.

I watched a lot of movies from all over the world. The Russians were very good at editing. They were specialists in editing. The Man with a Camera, if you know that movie, is incredible. I still don't understand how it works. It's a movie with no script, no actors and still it works. It's really good. It's really about editing.

I watched a lot of silent directors who were absolutely great like John Ford and Fritz Lang, Tod Browning, and also some very modern directors like The Coen Brothers. The directors take the freedom within their own movies to be melodramatic or funny when they chose to be. They do whatever they want and they don't care about the genre.

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
