The film is unusual for its period, in the days PRIOR to American entry into World War II, as the United States was still formally at peace with Nazi Germany. Chaplin's film advanced a stirring, controversial condemnation of Hitler, fascism, antisemitism, and the Nazis, the latter of whom he excoriates in the film as "machine men, with machine minds and machine hearts".[1]
The film was Chaplin's first "talkie", as well as his most commercially successful film. [2]
