Sherlock Jr. (1924) is an American silent comedy film directed by and starring Buster Keaton and written by Clyde Bruckman, Jean Havez and Joseph A. Mitchell. It features Kathryn McGuire, Joe Keaton and Ward Crane.
In 1991, Sherlock Jr. was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant." In 2000, the American Film Institute, as part of its AFI 100 Years... series, ranked the film #62 in its list of the funniest films of all time (AFI's 100 Years... 100 Laughs).
Although Sherlock Jr. was not a popular success in its day, it received critical praise from The New York Times, The Los Angeles Times, The Washington Post, and The Atlanta Constitution. Since its release, the movie has gone on to be recognized as a classic.
