For example, in your house, you have the heater on the ground itself. Here, it's the gravity. No matter where you are, that's where the gravity is coming from. It's almost like a carpet that you put down. If you're on the other side, it doesn't matter to us because we're still walking on the ground. Actually, at the beginning of the film [Valerian], we see when they install the gravity system.

I try to follow my instinct as a moviegoer and I do the thing I would love to see it at a movie. I'm like everyone, almost, I go to a movie once a week. I like every kind of film if it’s well made. I’m fine. I’m not a specialist fighting for a genre of film. You just have to follow your instinct.

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.

When I got the camera on the shoulder, they give me a nickname. They call me 'the tripod' because I'm kind of short and kind of strong. So if I take the camera and I lock myself, you think that you're on a crane.

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

I think it's the society that drains us out, and we are in a society where we are driven by money.

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.
