Sherlock, Jr. (1924)
#64 in my 2007 movie challenge was the Buster Keaton silent film Sherlock, Jr. Keaton plays a poor movie clerk displaced from his girlfriend’s affections when a thieving cad frames him for stealing a watch. There is a memorable dream sequence in which Keaton and the other characters intermingle on the screen. It’s worthwhile on its own, but far more arresting given the lack of technology available, as with Citizen Kane and Rules of the Game.
Bit of trivia: One of the writer’s was Clyde Bruckman, whose name was used in the title of one of my favorite X-Files episodes.
