EMILY: I caught some of Love in the Afternoon the other day, the movie. Have you seen it, Mom?
TRIX: I don’t believe I have.
EMILY: Oh, well, it’s wonderful. And a wonderful concept, too, don’t you think? Anyway, I must have the music stuck in my head. That must be why I’m singing it. I mean, what else could it be, hm?
Love in the Afternoon, 1957 romantic comedy film directed and produced by Billy Wilder, based on the 1920 novel, Ariane, Young Russian Girl, by French author. It stars Gary Cooper, Audrey Hepburn, and Maurice Chevalier. The story explores the relationship between a notorious middle-aged American playboy business magnate and the daughter of a private detective hired to investigate him.
The film was a failure at the box office in the US, as audiences thought Gary Cooper was too old to be having an affair with the much younger Audrey Hepburn. However, in Europe it was a major success, released under the name Ariane. The theme music “Love in the Afternoon” was written by jazz composer Matty Malneck.
