The Apartment is a 1960 American comedy-drama film produced and directed by Billy Wilder, which stars Jack Lemmon, Shirley MacLaine, and Fred MacMurray. It was Wilder's follow-up to Some Like It Hot and, like its predecessor, was a commercial and critical hit, grossing $25 million at the box office. The film was nominated for ten Academy Awards, and won five, including Best Picture.
C. C. Baxter (Jack Lemmon) is a lonely office drone for an insurance company in New York City. In order to climb the corporate ladder, Baxter allows four company managers to use his Upper West Side apartment for their various extramarital liaisons. Unhappy with the situation, but unwilling to challenge the managers, Baxter juggles their conflicting demands, while hoping to catch the eye of fetching elevator operator Fran Kubelik (Shirley MacLaine).
