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'm a big Star Wars fan.

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

I'm always attracted by people who are lost in their time. I think it helps us.

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.

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.

Be humble and say okay, all right, I have to prep myself. So everybody prepped, and we finished the film [Valerian ] four days before the end.
