Sherlock Jr. in the context of "AFI's 100 Years... 100 Laughs"

Joseph Frank "Buster" Keaton (October 4, 1895 – February 1, 1966) was an American actor, comedian and filmmaker. He is best known for his silent films during the 1920s, in which he performed physical comedy and inventive stunts. He frequently maintained a stoic, deadpan facial expression that became his trademark and earned him the nickname "The Great Stone Face".

Keaton was a child vaudeville star, performing as part of his family's traveling act. As an adult, he began working with independent producer Joseph M. Schenck and filmmaker Edward F. Cline, with whom he made a series of successful two-reel comedies in the early 1920s, including One Week (1920), The Playhouse (1921), Cops (1922), and The Electric House (1922). He then moved to feature-length films; several of them, such as Sherlock Jr. (1924), The General (1926), Steamboat Bill, Jr. (1928), and The Cameraman (1928), remain highly regarded. The General is perhaps his most acclaimed work; Orson Welles considered it "the greatest comedy ever made...and perhaps the greatest film ever made".
