Maurice Chevalier plays Philip Dulaine, a supposedly dying millionaire, while Sandra Dee co-stars as Cynthia, the elderly man's granddaughter. To allow Dulaine to die happy, Cynthia promises to find a husband. Actually, Dulaine is only pretending to be at death's door to get Cynthia married off. Subsequent complications involve Cynthia's personal choice for a husband, Warren Palmer (Andy Williams), and Dulaine's selection, Paul Benton (Robert Goulet). Deanna Durbin fans will quickly detect that I'd Rather Be Rich is a remake of Durbin's It Started With Eve (1941), with a gender switch (in the original, Robert Cummings is the grandson, and Durbin is the instant fiancee) and with Maurice Chevalier filling the sizeable shoes of Charles Laughton as the foxy grandpa.
