I saw Cara Delevingne like five, six times. And I was never talking about the film [Valerian]. And then at the end, I say okay, let's do some test. She says yeah, yeah, good. So I took her in the room, and I test her for like six hours non-stop. Exercise, exercise, exercise for six hours. It was actually funny. And then I knew at the end of the six hours.

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

Cinema never saved anyone's life, it is not a medicine that will save anyone's life. It is only an aspirin.

What a director is looking for is someone who will follow you and no matter what. And if you ask for blue, he's gonna try blue. And if you say, give me a piece of red with it, and they try. And you don't mind so much if it's difficult to get the blue and the red together. As long as they try. And as long as they give everything they can to give you what you want. That's what I'm looking for.

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.

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.

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.
