Directed by Robert Wiene, "The Cabinet of Dr. Caligari" is supposedly a masterwork of German Impressionism. I wouldn't know and don't care in that regard. This silent classic is the first great horror movie.
Werner Krauss plays the title role of Dr. Caligari. A hypnotist, he runs a side show with Conrad Veidt, who when placed in a trance can predict future events.
Events take a turn for the strange as Cesare, played by Veidt is found dead. Many might find a silent film difficult to follow, but this film just engages you and sucks you into an intricate web of suspense.
