Since Lava has shared his clips of the great Chaplin, I'd like to add one more. First released in October of 1940, The Great Dictator bitterly satirized Nazism and Adolf Hitler, which culminated in an overt political plea to defy fascism. Well before the full extent of the horrors of Nazism had been uncovered, Chaplin's film advanced a stirring, controversial condemnation of Hitler, fascism, and the Nazis, the latter of whom he excoriated in the film as "machine men, with machine minds and machine hearts."
This film was Chaplin's first talkie, and his most commercially successful film.
Lava, I know you're going to enjoy this!
