I looked at a lot of photos from Hollywood in the '20s, photographs of silent movies being filmed all over the world which are very specific and very evocative. Berenice, the lead actress, is my wife. She really followed the same path with me.

When you're with your wife, you don't say I love you to your wife every day but the ways you look at her and your actions are another way to communicate. Don't focus on dialogue, only focus on what you're expressing.

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

I think there's something in common with the OSS 117 movies. The big difference is there's no irony in this one. It's not parody. I tried to make it very simple. It's a simple story, but to be simple, it's very complex in the way it's done.

Sometimes when an actor says something almost perfect, but you know you have to edit it, if you tell them to change something immediately, it will come out great

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.
