Born Charles Joseph Parrott in Baltimore, Maryland, Charley Chase began performing in vaudeville as a teenager and started his career in films by working at the Christie Film Company in 1912. He then moved to Keystone Studios, where he began appearing in bit parts in the Mack Sennett films, including those of Charlie Chaplin. By 1915 he was playing juvenile leads in the Keystones, and directing some of the films as Charles Parrott. His Keystone credentials were good enough to get him steady work as a comedy director with other companies; he directed many of Chaplin imitator Billy West's comedies, which featured a young Oliver Hardy as villain.
