You can see that Isabelle Adjani is half Algerian and half German, because she has very dark hair and bright blue eyes. She plays a sensual revenge goddess, but the plot has a twist. In French films in the eighties a little more was allowed, but it's also a statement against abuse, without getting preachy.
The Vaucluse is bathing in the sun, and they have steep paths and little houses with chalked walls. The characters have good nicknames, like Pin-Pon for a fireman. The Yves Montand song has a mechanical waltz rhythm that suits the player piano.
