In this 1960 American comedy, Jack Lemmon stars as “Bud” Baxter, a go-getting office worker who loans his tiny apartment to his philandering superiors for their romantic trysts. He runs into trouble when he finds himself sharing a girlfriend (Shirley MacLaine) with his callous boss (Fred MacMurray).
Director/co-writer Billy Wilder claimed that the idea for “The Apartment” stemmed from a short scene in the 1945 movie “Brief Encounter” in which the illicit lovers arrange a rendezvous in a third person's apartment.
Wilder was intrigued about what sort of person would willingly vacate his residence to allow virtual strangers a playing field for hanky panky. His answer to that question wound up winning 6 Academy Awards, including Best Picture, Best Director, and Best Original Screenplay.
