I inadvertently stumbled on to this the other day while listening to Hans Zimmer on YouTube. The more I looked into this speech, the more fascinated I became with the film and the circumstances around it, take this from IMDB,
Gallup polls revealed that 96% of Americans opposed U.S. involvement in the war in Europe, and threatening letters from Nazi sympathizers poured into the studio. At one point, he even asked a friend with the Longshoreman’s Union in New York if they could have some union members present at the opening, to prevent a pro-Nazi demonstration.
In the 1940 movie, The Great Dictator, Charlie Chaplin gives the following climatic speech, now mixed with a little Hanz Zimmer (from every awesome soundtrack ever).
Words worth listening to, timeless & poignant.
