Let's Make Love is a breezy comedy about an off Broadway musical production. Jean-Marc Clement (Yves Montand) is the richest man in the world and looking for someone who loves him instead of his money. He reads in Variety he is to be satirized in the new production and tries out for the part. The producers hire him, unaware of his real identity. He hires Bing Crosby, Milton Berle and Gene Kelly to coach him for the role. Amanda (Marilyn Monroe) is the poor aspiring actress who lands a part in the play. Her opening number is the classic My Heart Belongs To Daddy. Unaware of his fabulous wealth, she falls for the playboy billionaire during the rehearsals for the show. Tony Randall plays Montand's fussy public relations agent and tries to keep his boss from embarassment.~ Dan Pavlides, All Movie Guide
