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.

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.

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

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

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

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

I was kind of surprised that, about 99 percent of the people grabbed the thing [in Valerian].You know it's their thing. And I'm very impressed by that.
