James Stewart once classified Pot O' Gold as his worst film, though this may have stemmed from his reported inability to get along with his costar Paulette Goddard (who is supposed to have dismissed Stewart's acting technique with a flippant "Anyone can swallow.") Inspired by the popular radio giveaway series of the same name, the film represented an ill-fated production venture for James Roosevelt, son of President Franklin D. Roosevelt. Stewart plays Jimmy Haskell, nephew of breakfast-food mogul C. J. Haskell (Charles Winninger). Befriending bandleader Horace Heidt (playing himself) and his orchestra members, Jimmy and his sweetheart Molly McCorkle (Paulette Goddard) tries to persuade C. J. to sponsor Heidt's radio program. The elder Haskell refuses until Jimmy and Molly's landlady mother (Mary Gordon) come up with a sure-fire "gimmick" for the program: they'll pick names from the phone book at random, call up those numbers, and give away huge prizes to whomever answers-provided that the call-ees are tuned
