Maybe I'm the only one who had never heard this, but I happened to find it the other day and I had to share. Everyone should hear this. I was so interested in the motivation behind it, so I watched this other video:
I never knew Charlie Chaplin was more than a comedian and a silent film movie star, but he was a true proponent of equality and human rights. His personally funded project of "The Great Dictator" was an astute model of how things would play out in the Holocaust and the power one man would hold over so many people.
