The Great Dictator is a 1940 American anti-war political satire black comedy written, directed, produced, scored by, and starring British comedian Charlie Chaplin, following the tradition of many of his other films. Having been the only Hollywood filmmaker to continue to make silent films well into the period of sound films, Chaplin made this his first true sound film.

The Academy Award for Best Original Screenplay is the Academy Award for the best screenplay not based upon previously published material. It was created in 1940 as a separate writing award from the Academy Award for Best Story. Beginning with the Oscars for 1957, the two categories were combined to honor only the screenplay.
