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.

That's a KORTAN DAHUK. That's the first alien we see in the film [Valerian]. That's another artist. The first one was Chinese, the one with the space station. This one is American. Personally, that's my favorite alien. I love him. I love his profile and his face. There is such a sweetness and almost a sadness in his face.

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

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.

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.
