This is a little comedy with a brilliant gimmick. Some of Hollywood's biggest stars of the time (1937) make brief appearances in this film, including Clark Gable, Greta Garbo, James Cagney, W.C. Fields, Charlie Chaplin and Harold Lloyd.
Now here's the gimmick: all of those big stars are played in this film by their own stand-ins, the wanna-be actors and actresses who had full-time employment in the Hollywood studios but who only kept working by copying the physical appearance of a better-known actor or actress and following that actor from one film role to the next.
