Triple Blu-ray set. The Keystone Film Company, under the guidance of pioneering producer and director Mack Sennett, was the birthplace of classic American slapstick comedy. This historic studio was at one time home to a staggering number of silent screen luminaries. Hollywood icon Charlie Chaplin, still the world's most recognized actor, introduced his beloved Tramp character under the auspices of Keystone. Later, under the Mack Sennett Comedies banner, Sennett went on to produce a new generation of sound comedies, some in early color. Now, for the first time, thanks to Flicker Alley, CineMuseum, and Keystone Films, the best surviving Sennett comedies have been gathered from around the world, fully restored, and digitally re-mastered in HD for Blu-ray home video. The Mack Sennett Collection, Vol. One features the first 50 of these films.
