"Ambassador of the Shadows" is the basis for Luc Besson's new film "Valerian and the City of a Thousand Planets."

From the publisher:

Point Central is a multicultural space station that serves as a sort of United Nations to the galaxy. Tasked with protecting the new ambassador from Earth, Valerian is kidnapped alongside his charge in a lightning commando attack. It's up to Laureline to do all the heavy lifting and slog through the seedy bowels of the station as she tries to locate and rescue them- and figure out who kidnapped them and why.

About the Author:

Jean-Claude Mezieres and Pierre Christin created Valerian in 1967 after working in the USA together, one as a cowboy, the other a teacher. While Valerian is Mezieres' only comic series, he's worked as an illustrator in many other areas, including designs and sets for The Fifth Element, and he was awarded the Grand Prix du festival d'Angouleme in 1984. Christin also works in collaboration with other artists, most notably Tardi and Bilal, and writes novels and film scenarios.
