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

I won't be able to do a film just for bad reasons, for money or for - I just can't. If I have one more where I feel I can bring you something, I will do it.

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.

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

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 never think about franchises, to be honest. I always just do the film.

Live your life, experience something, and then you're going to have a lot of things to say. But if you hang around in Hollywood, then you're going to say the same thing as everyone else - nothing.
