Idiot's Delight (1939) is a Hollywood film, with a screenplay adapted from the 1936 Robert E. Sherwood play, by Sherwood himself. The movie stars Norma Shearer and Clark Gable. It is notable as the only film where Gable sings and dances, performing a version of the Irving Berlin standard "Puttin' on the Ritz". However, it is not strictly a musical.
The language spoken by several European characters in this film is not identified in the dialogue, but is in fact Esperanto.
Norma Shearer's elaborate hairstyle in this film was copied from the hairstyle worn by Lynn Fontanne when she played the same character in the Broadway production of the stage play. The film's ending is considerably different from the play's ending, as well as more optimistic.
