Keepers: people possessed with a passion for preservation, individuals afflicted with a bad case of Archive Fever. The Keepers continues with the story of one such man, Henri Langlois, founder and curator of one of the world’s great film archives, the Cinémathèque Française. Henri Langlois never made a single film — but he's considered one of the most important figures in the history of filmmaking. Possessed by what French philosopher Jacques Derrida called "archive fever," Langlois begin obsessively collecting films in the 1930s — and by the outset of World War II, he had one of the largest film collections in the world. The archive's impact on the history of French cinema is legendary — as is the legacy of its controversial keeper.
