|Leonard Maltin/Plot synopsis:
Superb comedy-drama that manages to embrace both sentiment and cynicism. Lemmon attempts to climb corporate ladder by loaning his apartment key to various executives for their extramarital trysts, but it backfires when he falls for his boss's latest girlfriend. Fine performances all around, including MacMurray as an uncharacteristic heel. Oscar winner for Best Picture, Director, Screenplay (Wilder and I. A. L. Diamond), Editing (Daniel Mandell), Art Direction-Set Decoration (Alexander Trauner, Edward G. Boyle). Later a Broadway musical, Promises, Promises. Panavision.
