Sherlock Jr.

Sherlock Jr. is a 1924 American silent comedy written, directed by and starring Buster Keaton as a film projectionist who dreams himself directly into the movie he is screening, becoming a detective navigating a plot assembled from the conventions of the crime pictures of the day. The film is noted for technically intricate visual effects and stunts, including a sequence in which Keaton's dream-self is disoriented by a rapid series of scene changes edited to place him convincingly inside each new setting, all achieved through in-camera trickery rather than later manipulation of the film. Sherlock Jr. is widely regarded as one of Keaton's most technically accomplished films and an influential early exploration of cinema's own illusion-making within a film's own story.
