Silent Horror Film

The German silent movie "The Cabinet of Dr. Caligari" centers on two murders in the small town of Holstenwall. The movie's title character is the director of an insane asylum, who falls under suspicion when he arrives in town the day of the first murder. Filmed in 1919, the movie was directed by Robert Wiene and written by Hans Janowitz and Carl Mayer. It was a forerunner of such psychological thrillers as Alfred Hitchcock's "Psycho" and Roman Polanski's "Repulsion." 7 p.m. Tuesday. St. John's College, 60 College Ave., Annapolis. Free. 410-626-2539.
