My biggest surprise is probably the level of involvement of all the artists [in Valerian] who participated at every level.

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 wanted to do something that was entertaining - but with a catch.

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.

Cara [Delevingne] I wanted to be sure that she would be involved. 'Cause she didn't do a lot of films before I met her, so I didn't know if she was serious and so I push her a bit.

Loving a film is like falling in love with a woman or with a man like you never expect it. It it's not the one you think you will be in love with, you know. You think always that he will be with a beard, and black, and big and finally he's Chinese and you know it's the same thing. There's something very organic about the film and if you forgot it, if you don't have this seed in it...this organic flavor in it the film doesn't work it's wrong.

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.
