The Greet Dictator Speech

Came across this great clip on YouTube.com from the movie The Great Dictator (1940) staring Charlie Chapman. The clip has been chopped and edited with modern clips but the speech is all Charlie. I've looked for the movie but haven't found it yet. Reviews of the film state that the movie is a comedy but this clip seems to me to have a real serious meaning. The movie was created in the WWI era, but I feel the clip has prevalence today. Awesome clip!
