Like Clint Eastwood, Charlie Chaplin is better known as an actor. But his filmography is more akin to a Woody Allen type, meaning that the better description for what he does is "actor-director," as Chaplin directed just about every film in which he ever starred (IMDb lists 72 directing credits and 86 for acting).

Simply put: if there were no Charlie Chaplin the director, there would be no Charlie Chaplin the actor. And the world of film would be much worse off for it.
