In 1920, one brilliant movie jolted the postwar masses and catapulted the German Expressionist film movement into history. That movie was The Cabinet of Dr. Caligari, a plunge into the mind of insanity that severs all ties with the rational world. Director Robert Wiene and a team of visionary designers crafted a nightmare realm in which light, shadow and substance are abstracted, a world in which a demented doctor and a carnival sleepwalker perpetrate a series of ghastly murders in a small community.
