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.

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.

That's the storyboard that we have in the beginning [of Valerian]. It's an easy shot. It's just a spaceship coming in. That's the first layout. On the first layout, we see the timing of the shot and the speed. It starts to get some shadows, and we see that everything is moving in the back.

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

I think we have the wrong notion of commercial and intellectual or artistic film. Because all films are commercial.

Sometimes I see people finish a film and they go, "Yeah, that was good. Where are we going to eat?"

My concern 99% is about the storytelling, the emotion and all this. I never think about the format of anything until way far in the process and when we arrive to the fabrication of the thing then we start to say, "Okay right, what is the best thing we can do." I choose the car before to choose the color.
