Adapted from the book and play of the same name, The Happiest Millionaire is the (mostly) true story of eccentric Philadelphia millionaire Anthony J. Drexel Biddle (Fred MacMurray). The Biddle mansion is the gathering place for a pugilistic boxing class, pet alligators and would-be opera singers. Cordelia Biddle (Lesley Ann Warren), the daughter of Anthony and his wife (Greer Garson), wants to marry wealthy and handsome Angie Duke (John Davidson), but Angie's parents are shocked by the Biddles' freewheeling lifestyle. Thanks in part to the ebullient intervention of John Lawless (Tommy Steele), the Biddles' butler, all misunderstandings are eventually swept away. Like Disney's previous Mary Poppins, The Happiest Millionaire is decked out with a vibrant musical score by Richard and Robert Sherman, but the magic is somehow lacking this time around. This was the last live-action film to personally supervised by Walt Disney; released several months after Disney's death, the film was made available in 141-minute and 164-minute versions.
