Kiss Me, Stupid (1964)

Director: Billy Wilder

While traveling home from Vegas, an amorous lounge singer named Dino gets conned by a local mechanic/songwriter into staying in town for the night. The mechanic's songwriting partner, Orville, offers Dino his home for overnight lodging and enlists a local waitress/call girl to pose as his wife in order to placate Dino's urges.
