Bing Crosby stars in this light and lively musical version of Mark Twain's timeless comedy. Der Bingle is a turn-of-the-century blacksmith who is knocked unconscious only to awaken in sixth-century Camelot. But thanks to some American know-how, the crooner is quickly hailed as a wiz of a wizard and granted the right to teach Rhonda Fleming, the King's fetching niece, some decidedly contemporary romantic tricks. Alas, there's trouble afoot when Bing locks "magical" horns with the all-powerful Merlin and is challenged to a joust by Sir Lancelot for the hand of the beautiful princess! Co-starring Sir Cedric Hardwicke and William Bendix, the classic fantasy also features a marvelous score by Jimmy Van Heusen and Johnny Burke, along with such hits as "Busy Doing Nothing" and "Once and for Always."
