who was the creator of keystone film corp and specialized in slapstick comedy films
Keystone Studios The studio is perhaps best remembered for the era under Mack Sennett when he created the slapstick antics of the Keystone Cops, from 1912, and for the Sennett Bathing Beauties, beginning in 1915. Charles Chaplin got his start at Keystone when Sennett hired him fresh from his vaudeville career to make silent films. Charlie Chaplin at Keystone Studios is a 1993 compilation of some of the most notable films Chaplin made at Keystone, documenting his transition from vaudeville player to true comic film actor to director. In 1915, Keystone Studios became an autonomous production unit of the Triangle Film Corporation with D. W. Griffith and Thomas Ince. In 1917, Sennett gave up the Keystone trademark and organized his own company.
