Cara [Delevingne] I wanted to be sure that she would be involved. 'Cause she didn't do a lot of films before I met her, so I didn't know if she was serious and so I push her a bit.

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.

When I got the camera on the shoulder, they give me a nickname. They call me 'the tripod' because I'm kind of short and kind of strong. So if I take the camera and I lock myself, you think that you're on a crane.

I would rather stop [making movies] too soon than too late.

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].

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.
