The Green Room is a 1978 French historical drama film directed by François Truffaut, based on the 1895 short story "The Altar of the Dead" by Henry James, in which a man becomes obsessed with the dead people in his life and builds a memorial to them. It is also based on two other works by James: the 1903 novella The Beast in the Jungle and the 1896 short story "The Way It Came". It was Truffaut's seventeenth feature film as a director and the third and last of his own films in which he acted in a leading role. It stars Truffaut, Nathalie Baye, Jean Dasté and Patrick Maléon.
