Buster Keaton was a master silent film comedian in the 1920s comparable to Charlie Chaplin. After 15 years, the advent of sound and his personal troubles with alcohol and interference from the studio caused the swift and sudden crash of his career and personal life. Recognized later by film historians and the public for his hilarious movies, Keaton continued to work until his death. In The Persistence of Comedy Imogen Sara Smith brings together all the historical research on Keaton and his films with a discerning, but loving eye and wonderfully readable prose. Illustrated with stills from Keaton's classic movies.
