Chaplin doing all his stunts. Jackie Chan was inspired by many of them.
Almost all Chaplin's movies are praised for their depiction of society in the first half 20th century.
Chaplin directing The Great Dictator. We're talking about the 40's, when Hitler was alive, conquering, killing, spreading fear and hate. Making a movie where the most feared man in the world is ridiculed, shown as a buffoon, and making actual comedy out of his reign... Chaplin has BALLS!!!
In what turned out to be the start of the Hollywood blacklist by the House Un-American Activities Committee, there were rumors that chairman J. Parnell Thomas would subpoena Chaplin to defend his loyalty. Chaplin sent a preemptive telegram telling Thomas he could have save the taxpayers money by calling him collect on the matter. Chaplin went on to conclude, "In order to be completely up-to-date on my thinking I suggest you review my latest production, Monsieur Verdoux. It is against war and the futile slaughter of youth. I trust you will not find its humane message distasteful. While you are preparing your engraved subpoena I will give you a hint on where I stand. I am not a Communist. I am a peacemonger."*
