Chaplin at Keystone(2012)

Charles Chaplin came to Mack Sennett’s Keystone Studios late in 1913 as a little-known British vaudevillian, and after a year, had not only established his Tramp character, learned to write and direct his own films, and also achieved public recognition as a star comedian. Although Keystone did not publicize its performers by name, standees of Chaplin's likeness outside theaters sufficed to attract audiences. Some of the films, especially TILLIE’S PUNCTURED ROMANCE (1914), remained in theatrical distribution for decades.
