Andrew Sarris called it Keaton’s 8 1/2, and in the end Sherlock Jr. will be Keaton’s most enduring commentary on the art of cinema, which has the power to make artists of us all. Buster plays a projectionist who dreams his way onto the screen and into a movie in which he resolves the conflicts of his own life. As early as 1925, Sherlock Jr. was recognized by René Clair for its Pirandello-like dramatic structure, and it was much admired by the French Surrealists. The film is equally impressive for Keaton’s brilliantly modulated acrobatics, cinematic miracles performed without special effects.
