You know that Luc Besson puts his own life in the balance with this movie!!!!
Here, "Valerian et l'empire des mille planètes" is a very VERY popular graphic novel from 1967 (2 500 000 sales). Besson has always wanted to make his own Space Opera and made a first try with the "fifth element". Now, by buying for the adaptation of "Valerian", he has a set of 21 graphic novels to make a very good set of movies ...
... but if he makes something wrong with Valerian ... he will be hunted
So, after Rogue One, i can not wait for this Valerian
