I did The Fifth Element and [Jean-Claude] Mezieres, the artist of Valerian; he was working on Fifth Element. And he's actually the one who say, why don't you do Valerian? And I said because we can't make it. And you really have to wait for Avatar and to suddenly think oh okay, maybe we can think of it. But before Avatar, just forget it.

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.

We have [in Valerian] a bible that's 600 pages. There are five pages on each alien and where they come from. Even the address you can check on the map. On the star map. It's real numbers.

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.

You know sometimes you're in a position of risk and you feel that you can turn good or bad.

I never think about franchises, to be honest. I always just do the film.

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