This is a very short documentary about Frenchman Jean Giraud, aka Moebius the artist, and so my review is going to be short.
Written and directed by Hasko Baumann, this documentary traces the professional life and influences of an artist whom comic book aficionados will have come across one way or another. As a film it's pretty standard fare with the talking heads styled interview with various close collaborators, and folks from the US comics industry such as Stan Lee (whom he worked together with in Silver Surfer) and Mike Mignola, better known for his Hellboy series.
For film lovers, a good introduction to Jean Giraud is that he's the creative force behind the designs you see in 5th Element, Tron, Alien and even inspired the design of the city in Blade Runner with some panels from an earlier comic work. He too had a hand in providing some designs for a Dune movie, whose production unfortunately got canned.
Interspersed with various art pieces from comic books and set/character designs for the movies he's worked on, this documentary remains strictly for the fans, otherwise you'll be clueless and point at Stan Lee each time he comes on screen, saying "did he create Spider-Man?" trying hard to impress your equally clueless girlfriend. At least the couple sitting beside me were that clueless, and I got to shush them from bombarding me with useless trivia.
