Diabolique (1955) [The Criterion Collection]

Before Psycho, Peeping Tom, and Repulsion, there was Diabolique. This thriller from Henri‑Georges Clouzot, which shocked audiences in Europe and the U.S., is the story of two women – the fragile wife and the willful mistress of the sadistic headmaster of a boys' boarding school – who hatch a daring revenge plot. With its unprecedented narrative twists and terrifying images, Diabolique is a heart-grabbing benchmark in horror filmmaking, featuring outstanding performances by Simone Signoret, Véra Clouzot, and Paul Meurisse.
