I think being a foreigner and talking about Hollywood allowed me to use some cliches and some references that an American would maybe not use.

I want to thank three person: I want to thank Billy Wilder. I want to thank Billy Wilder. And I want to thank Billy Wilder.

Usually, when you do a period movie, you just recreate what you are shooting. You don't recreate the way you shoot it. I think I did the same thing here as I did in the OSS 117 movies. I recreated the way to shoot that period, because to me, like what I was saying about the Steadicam, there's no sense to do a Steadicam shot in the 1920s because you have never seen the '20s like that. You can't believe there was a Steadicam in the 1920s. I believe it's a continuation of the OSS 117 in a way but without the irony.

There's always been a struggle with filmmakers between art and industry, and you have to find a balance

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.

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.

People inside the theaters usually, not 100 percent but most of them, enjoy the movie. Usually they come with a small negative view. In a way, they're prepared to get bored because it's silent and because it's black and white. So they are much more pleased to be entertained in a way. They're very happy when they go out. This was my job. For the other ones, I can do nothing except screen the movie and hope that they will say to their friends that it's not so [bad].
