Sade is a 2000 film directed by Benoît Jacquot, adapted by Jacques Fieschi and Bernard Minoret from the novel La terreur dans le boudoir by Serge Bramly.

The fictional story takes place during the Reign of Terror in France and centers around the Marquis de Sade (played by Daniel Auteuil) who is imprisoned on a country estate with several other noble families, all awaiting an uncertain future. The marquis relives the adventures of his youth and befriends a young woman, Emilie de Lancris (played by Isild Le Besco), whom he instructs in the secrets of love. He also works to overcome the other inmates' resistance to his libertine philosophy.
