The Great Dictator is a 1940 American comedy-drama film starring, written, produced, scored, and directed by 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, this was Chaplin's first true talking picture as well as his most commercially successful film.
At the time of its first release, the United States was still formally at peace with Nazi Germany. Chaplin's film advanced a stirring, controversial condemnation of Adolf Hitler, Benito Mussolini's fascism, antisemitism, and the Nazis, whom he mocks in the film as "machine men, with machine minds and machine hearts".
This speech means as much today as it did in 1940 however today the enemy is much closer to home.
