The Cabinet of Dr. Caligari is a 1920 German silent horror film directed by Robert Wiene and written by Hans Janowitz and Carl Mayer. Considered the quintessential work of German Expressionist cinema, it tells the story of an insane hypnotist who uses a brainwashed somnambulist to commit murders. The film features a dark, twisted visual style, with sharp-pointed forms, oblique, curving lines, structures and landscapes that lean and twist in unusual angles, and shadows and streaks of light painted directly onto the sets.

Robert Wiene was a German film director, screenwriter and producer, active during the silent era. He is widely-known for directing the landmark 1920 film The Cabinet of Dr. Caligari and a succession of other expressionist films. Wiene also directed a variety of other films of varying styles and genres. Following the Nazi rise to power in Germany, Wiene, who was of Jewish descent, fled into exile.
