Considered the quintessential work of German Expressionist cinema, it tells the story of an insane hypnotist (Werner Krauss) who uses a brainwashed somnambulist (Conrad Veidt) 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. The script was inspired by various experiences from the lives of the directors, both pacifists who were left distrustful of authority after their experiences with the military during World War I. The film makes use of a frame story, with a prologue and epilogue combined with a twist ending.
