I have like 10 actors and 100 aliens in the film [Valerian]. And they come from the four corners of the universe. Some of them are liquid. Some of them are just [so visually] crazy.

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.

You know, it's not my film [Valerian], it's really their film. It's very strange. And maybe because it's more when you comes to the Marvel films it's way much more organized and plan, you know, they planned. Okay, we have Thor here, we have this and then we do The Avengers, and then we group. You know, it's much more organized. So maybe there is a little less freedom at the end for the creative people. Where I did the entire opposite. I let them help me, you know. So that's also why maybe they were so involved.

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.

I don't want to show kids that I am smoking.

If you're someone from the government and you meet people from other countries, you want to know who you're dealing with. It's the same for them [in Valerian].

We have [in Valerian] a bible that's 600 pages. There are five pages on each alien and where they come from. Even the address you can check on the map. On the star map. It's real numbers.
