the apartment

Billy Wilder's "The Apartment" (1960) won five major Academy Awards out of ten nominations, including Best Picture, Best Director, Best Screenplay, Best B/W Art Direction/Set Decoration, and Best Film Editing, Jack Lemmon for Best Actor, Shirley MacLaine for Best Actress and Jack Kruschen for Best Supporting Actor. It was a triple win for Wilder as Director (Wilder's second directing Oscar), Producer, and Screenplay author.

The movie is the cynical story of an average clerk who lends his apartment to different superiors for their various sexual escapades in exchange for them helping him get a higher position within the company. The plot complicates the moment when he realizes that the woman he fell for is the very lover of his married "big boss", who also uses his apartment rental services.
