The Apartment
The Apartment is a 1960 film produced and directed by Billy Wilder, and starring Jack Lemmon, Shirley MacLaine, and Fred MacMurray. It was Wilder’s follow up to the enormously popular Some Like it Hot and was an equal commercial and critical hit, grossing $25 million dollars at the box office, and winning the Academy Award for Best Picture.
It was later adapted by Neil Simon, Burt Bacharach and Hal David into the Broadway musical Promises, Promises.
