La maison Bonnadieu (1951)

Felix is a middle-aged bourgeois husband. Much to his discomfort, he learns that his wife Gabrielle is carrying on with a young man--a very young man. Rather than express outrage, Felix decides that there's something lacking in him. He spends the rest of the picture trying to keep his wife by altering his own personality and outlook.

The movie La maison Bonnadieu, released in 1951, features 1 song from Marcel Mouloudji.
