What a director is looking for is someone who will follow you and no matter what. And if you ask for blue, he's gonna try blue. And if you say, give me a piece of red with it, and they try. And you don't mind so much if it's difficult to get the blue and the red together. As long as they try. And as long as they give everything they can to give you what you want. That's what I'm looking for.

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.

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

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.

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.

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

I wrote the entire history of Alpha because the space station was around for 500 years. I have 30 pages on the history of Alpha. Every ten years what happens. They took control and what happened. Every 80 years, they have to change the communication system because it doesn't work anymore. Some aliens come with new technology, and suddenly you can change the electric system. We wrote the entire story [for Valerian]
