From 1913 to 1916, Roscoe "Fatty" Arbuckle rose from the ranks of bit player to writer, director and star of comedies for Mack Sennett's Keystone Film Company. Because of Sennett's belief that actors were interchangeable, he lost Arbuckle to producer Joseph M. Schenck, who not only paid the comedian handsomely, but also permitted him complete creative control. To help in the new venture, Arbuckle recruited Buster Keaton, popular star of a knockabout vaudeville act; Keaton took a large pay cut to act in motion pictures, and Arbuckle welcomed his ideas and taught him all he knew about making movies. This volume of the DVD collection presents films that Arbuckle and Keaton made for Schenck between 1918 and 1919; they are presented chronologically so we can watch Buster grow from Arbuckle's bit player to his full partner.
