We talked a lot with the musician. And for now there are few options, and I give him few weeks to come and surprise me with something. I don't want to start and say, okay here is what I want. Because maybe he has an idea that is better than mine.

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

When Cara [Delevingne] and Dane [DeHaan] arrived, I told their agent, "They need to know all this." I gave them the 600 pages. I said, "You have to learn everything. You're a cop. You need to know the names." I don't want him, when he meets an alien to go, "Whoa" like this. I want him to know if this guy is peaceful.

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.

I'm a big Star Wars fan.

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

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.
