The Green Room (1978)

Julien Davenne (François Truffaut) is a French writer who becomes consumed with the concept of death. After losing many friends during the fighting in World War I, Julien constructs a shrine to those close to him who died in battle. At the heart of Julien's obsession is his late wife, whom he honors throughout his home, which is essentially one large memorial dedicated to her memory. Though Julien makes fleeting attempts to connect with the living, he seems more comfortable with the dead.
