Sidney Drew Fatty Arbuckle Charles Chaplin Mack Sennett film
Sidney Drew was the leader in developing "polite comedy", while slapstick was refined by Fatty Arbuckle and Charles Chaplin, who both started with Mack Sennett's Keystone company. They reduced the usual frenetic pace of Sennett's films to give the audience a chance to appreciate the subtlety and finesse of their movement, and the cleverness of their gags. By 1917 Chaplin was also introducing more dramatic plot into his films, and mixing the comedy with sentiment.
