I'm always attracted by people who are lost in their time. I think it helps us.

I think we have the wrong notion of commercial and intellectual or artistic film. Because all films are commercial.

We were so ready [with Valerian] that we were early, which is unheard of in the history of the sci-fi film.

What a director is looking for is someone who will follow you and no matter what. And if you ask for blue, he's gonna try blue. And if you say, give me a piece of red with it, and they try. And you don't mind so much if it's difficult to get the blue and the red together. As long as they try. And as long as they give everything they can to give you what you want. That's what I'm looking for.

We talked a lot with the musician. And for now there are few options, and I give him few weeks to come and surprise me with something. I don't want to start and say, okay here is what I want. Because maybe he has an idea that is better than mine.

Be humble and say okay, all right, I have to prep myself. So everybody prepped, and we finished the film [Valerian ] four days before the end.

For example, in your house, you have the heater on the ground itself. Here, it's the gravity. No matter where you are, that's where the gravity is coming from. It's almost like a carpet that you put down. If you're on the other side, it doesn't matter to us because we're still walking on the ground. Actually, at the beginning of the film [Valerian], we see when they install the gravity system.
