A deranged doctor performs ghastly experiments at his secluded country home. A murdered man’s body vanishes from the depths of a filthy swimming pool. A mysterious samurai spirit behind a demonic mask stalks two women isolated in a hut surrounded by tall grasses. The Criterion Collection is filled with terrifying stories to tell in the dark, from silent horror (Benjamin Christensen’s 1922 witches’ brew Häxan) to contemporary gore (Lars von Trier’s controversial gut-wrencher Antichrist). There’s much to fear in the films below, whether it’s a disembodied brain, a murderous blob, or Boris Karloff.
