At the very beginning, it's a desire and that's not the same thing at all, because when you have the desire to do something, all the work you can do is a positive thing. It's not something that you calculate. An idea is something you work on to make it work and a desire is much deeper in a way. The immersion, it's classical, I watched a lot of movies.

I went to Hollywood. I put the action in Hollywood. I watched a lot of movies, maybe 100 or something close to that. I have tons of DVDs now at home. I don't know what to do with them because they're not useful anymore. My kids never watched them. I read a lot of autobiographies, listened to a lot of music by classical era composers like Franz Waxman, Max Steiner, Bernard Herrmann, Alfred Newman and Leonard Bernstein. I listened to only that kind of music the entire time I was writing, even at home.

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 guess all the directors in France are influenced by Hitchcock, because he's the perfect visual director, in my eyes.

All over the world there are a lot of distributors that have the equipment for 3D but they don't have the movies really. The only source of 3D movies is Hollywood. Only Hollywood sends the 3D movies. So it was an option.

I think we are at the very beginning of high changes, not only in terms of digital film, but in the way the movies will be screened, whether they'll be screened on phones, on computers - on everything
