The life and filmmaking career of iconic comedian Buster Keaton is celebrated in this documentary. Starting life in show business as a toddler in his family's vaudeville act, Keaton rose to fame in his visionary silent comedies of the 1920s. The later years of his career (which were filled with personal and professional difficulties) are also chronicled. However, the film returns to highlights from his brilliantly productive period to showcase the creativity, fearlessness and physical talents that made Keaton a comedy legend.
