The most viewed film is Das Cabinet des Dr. Caligari. (The Cabinet of Dr. Caligari) (1920) . In one of the most popular movies of the silent period, Werner Krauss plays the main character, a sinister hypnotist who travels the carnival circuit displaying a somnambulist under the name Cesare (Conrad Veidt). In one tiny German city, a series of murders coincides with Caligari’s visit. When the best friend of man Francis (Friedrich Feher) is killed, the deed seems to be the outgrowth of a romantic rivalry over the hand of Jane (Lil Dagover). Francis suspects Caligari, but he is ignored by the police. Investigating on his own, Francis seemingly discovers that Caligari has been ordering the somnambulist to commit the murders, but the story eventually takes a more surprising ending. Caligari’s Expressionist style ultimately led to the dark shadows and sharp angles of the film noir urban crime dramas of the 1940s, many of which were directed by such German émigrés as Billy Wilder and Robert Siodmak.
