L'Ennui (English: Boredom) is a 1998 erotic drama film directed by Cédric Kahn from a screenplay he co-wrote with Laurence Ferreira Barbosa, based on the 1960 novel La noia by Alberto Moravia. The film stars Charles Berling, Sophie Guillemin and Arielle Dombasle, with Robert Kramer, Alice Grey and Maurice Antoni. It follows the life of a bored philosopher as he becomes jealously obsessed with the much younger lover of a dead painter.
