Revenge is sweet in this week’s festival of free films on Hulu. These are thrillers, medieval-set dramas of honor and faith, and even a comedy. In Henri-Georges Clouzot’s classic chiller Diabolique, an abusive schoolmaster’s wife and mistress plot to murder him. Shohei Imamura’s Vengeance Is Mine follows a thief and murderer taking out his aggression on society in the form of a remorseless killing spree. An ex-con patiently waits for the right moment to kill a man who ruined his life in Götz Spielmann’s gripping, Academy Award–nominated Revanche. In White, the droll middle entry in Krzysztof Kie?lowski’s Three Colors trilogy, a hapless hairdresser tries to start his life anew—and get elaborate revenge on his ex-wife—following a nasty divorce. Tatsuya Nakadai plays a mysterious samurai with a secret in Masaki Kobayashi’s tale of violence and corruption in medieval Japan, Harakiri, while in medieval Sweden a grieving father (a ferocious Max von Sydow) takes revenge on the men who raped and murdered his daughter, in Ingmar Bergman’s Oscar-winning masterpiece The Virgin Spring. And here’s a rare treasure: Obsession, a 1949 British thriller by blacklisted and exiled American noir master Edward Dmytryk concerning a London psychiatrist (Robert Newton) who fashions a nasty comeuppance for his wife’s lover, whom he kidnaps and keeps chained in his basement. Not available on DVD or Blu-ray, Obsession can be viewed below or at Hulu for free.
