In 1920, one brilliant movie jolted the postwar masses and catapulted the movement known as German Expressionism into film 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 visionary team of 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. This authoritative edition of The Cabinet of Dr. Caligari is a 4K restoration scanned from the (mostly) preserved camera negative at the German Federal Film Archive.
