Here are just a few of the high points in the history of cinematic horror...
1920: The Cabinet of Dr. Caligari: This German expressionist classic would go on to influence horror, science fiction, and film noir.
1922: Nosferatu: Actor Max Schrek, who took his role perhaps a little too seriously, is the creepiest vampire in film history. (Schrek's performance is memorably rendered by Willem Dafoe in Shadow of the Vampire.)
1925: Phantom of the Opera: Lon Chaney becomes the first major horror film star.
