In this musical comedy, billionaire Jean-Marc (Yves Montand) falls for showgirl Amanda (Marilyn Monroe). When Jean-Marc hears he's the subject of a spoof in a revue Amanda is rehearsing, he convinces the producers to allow him to portray himself so he can be near Amanda. Jean-Marc then hires Bing Crosby, Milton Berle and Gene Kelly (playing themselves) to teach him the tricks of the trade.
