Sherlock Jr.

Sherlock Jr. is a 1924 American silent comedy directed by and starring Buster Keaton, in which a small-town cinema projectionist, wrongfully accused of theft, falls asleep in his booth and dreams himself into the film he is screening as "Sherlock Jr., the world's greatest detective"¹^•². The film is known for its pioneering special effects, dangerous stunts, and a film-within-a-film structure that anticipates later self-reflexive cinema¹^•³.

Premise

Keaton plays a projectionist and janitor at a small-town movie theater who studies to be a detective by reading a book titled How to Be a Detective. He is short of money, loves a local girl (Kathryn McGuire), and competes for her with a dishonest rival, the Sheik (Ward Crane). The Sheik steals a watch from the girl's father and frames the projectionist for the theft, using techniques from the projectionist's own detective book⁶^•⁸.

Falling asleep in the projection booth while a film runs, the projectionist dreams that he leaves his body, walks through the auditorium, and enters the movie on the screen. There he becomes "the world's greatest detective, Sherlock Jr.", solving a stolen-necklace case that mirrors his own situation and winning the girl in the dream²^•⁹. In the film's last scene, the waking Keaton looks to the movie on his screen to learn how to act with his girlfriend³.

Production

The working title was The Misfit³. Keaton spent five months on the film and took it out for three audience previews, cutting it after each; the final cut ran 5 reels, roughly a reel (about ten to twelve minutes) shorter than most comedy features of the period⁶^•³. His patron, producer Joseph Schenck, and his distributor implored him to flesh the film out to feature length¹⁰.

The International Buster Keaton Society credits the direction to Buster Keaton and Roscoe Arbuckle⁴; the AFI Catalog notes that modern sources state Arbuckle may have directed some scenes². Portions were shot in Glendale, California, and in Los Angeles around Los Feliz, Echo Park, and near the intersection of Larchmont and Beverly Boulevards².

The only character given a name in the film besides the title role is Gillette, the theater manager played by Ford West. The name is a tongue-in-cheek reference to the razor brand and an homage to the stage actor William Gillette (1853–1937), famous for portraying Sherlock Holmes on stage and in the 1916 film Sherlock Holmes².

Stunts and visual effects

Keaton pushed the special effects of his day to their limits while also drawing on old vaudeville stage mechanics, such as the moment when he leaps "through" his disguised assistant to evade pursuers¹. In the best-known sequence, the dreaming Keaton, standing in the onscreen scene, remains in the same position as the scenery changes repeatedly around him, a feat accomplished by changing the sets while keeping Keaton precisely in the same position relative to the camera, utilizing measurements and surveying instruments¹^•¹². Cinematographers and technicians of the era reportedly viewed the film repeatedly, trying to work out how certain scenes were accomplished³.

The stunts carried real risk. Jumping from the top of a moving freight car and swinging down to grab a water tower's release rope, Keaton was thrown by the force of the escaping water onto the track, striking his head on a rail. The 29-year-old Keaton got up and finished the scene, but suffered headaches for days; years later, a routine medical examination with X-rays revealed he had fractured his neck in the incident¹¹^•⁶.

Reception and legacy

On its release in April 1924 the film was only a modest success, and Keaton did not regard it as one of his big pictures¹⁰. Reviews were mixed: the trade paper Variety described it as "about as unfunny as a hospital operating room"³. Its reputation has grown steadily since; film historians now cite its special effects, elaborate stunts, and exploration of film illusion versus reality as landmarks in motion picture history².

The film's self-reflexive structure, a comedy that takes place largely inside a movie and about moviegoing, anticipated later filmmakers. Jeffrey Vance, a film historian and archivist, notes that its innovations influenced Woody Allen's The Purple Rose of Cairo (1985), and that Tom Cruise's "Mission: Impossible" films, George Lucas's "Star Wars" prequels, and Disney/Pixar animators have studied it for stunts and visual comedy³. The BFI describes it as anticipating Jean-Luc Godard and postmodernism by decades¹, and Pauline Kael called it "a piece of native American surrealism"⁶. In the 2022 Sight and Sound poll of the greatest films of all time, it ranked joint 54th⁷.
