The last of director Éric Rohmer's six "Comedies et Proverbes" series of movies of the 1980s. The other five, in chronological order, are La femme de l'aviateur (1981), Le beau mariage (1982), Pauline at the Beach (1983), Les nuits de la pleine lune (1984) and Le rayon vert (1986).
Cergy-Pontoise, where the film takes place, is a new town and an agglomeration community in France, in the Val-d'Oise and Yvelines departments, northwest of Paris on the river Oise.
The title literally means the (male) friend of my (female) friend, or perhaps the boyfriend of my girlfriend; it echoes the proverb: "Les amis de mes amis sont mes amis" - "Friends of my friends are my friends".
The first title of the film was "Les Quatre Coins" ("The Four Corners").
