Valerian and Laureline are a pair of galaxy hopping special agents who are dropped into trouble spots anywhere in space and time. It's like a French Star Trek.
Jean-Luc Besson's 2017 feature film is based upon this classic bande dessinee series.
From the publisher:
When a rogue planet threatens a new Human colony, Valerian and Laureline are sent to investigate and discover a barren, rocky surface and a whole world beneath it! The people who live inside Zahir have never seen the stars. Divided along gender lines, torn by a senseless and bloody war, they are unaware that their planet is hurtling towards disaster. To stop it, the two agents of Galaxity will have to infiltrate both sides and force a reconciliation.
About the Authors
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.
