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.

That's the storyboard that we have in the beginning [of Valerian]. It's an easy shot. It's just a spaceship coming in. That's the first layout. On the first layout, we see the timing of the shot and the speed. It starts to get some shadows, and we see that everything is moving in the back.

I wanted to prove that I could do something, so I made a short film. That was in fact my main concern, to be able to show that I could do one.

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

After six, seven films, I started to get a little tired. Shooting takes a lot out of you.

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.

I wanted to do something that was entertaining - but with a catch.
