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 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.

My biggest surprise is probably the level of involvement of all the artists [in Valerian] who participated at every level.

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

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.

It's always the small people who change things. It's never the politicians or the big guys. I mean, who pulled down the Berlin wall? It was all the people in the streets. The specialists didn't have a clue the day before.

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.
