"The Great Dictator" Charlie Chaplin (1940)

By appropriating the satiric tone, Chaplin denounced in his film "The Great Dictator" dictatorial regimes that plague Europe. Throughout his film, Chaplin draws up the caricatural portrait of Hitler and thus, incriminates the harmful nature of Nazi imperialism under all its aspects.
Unfortunately, the current recidivist nature of dictatorship and conspiracy gives more meaning to this prescient film.
