Whatever you do, don’t hire a nanny. It’s a message that comes up again and again in movies about the destructive force that can be unleashed when you bring a stranger into your house, in films like The Hand that Rocks the Cradle, or William Friedkin’s schlocky The Guardian. One of the landmarks of Korean cinema hits on the same territory: Ki-young Kim’s 1960 film, The Housemaid, which addressed the pains of upward middle-class mobility via the story of a family that hires a young woman they can barely afford to help them cook, clean, and watch their kids. She then seduces the father, gets pregnant, causes the death of one of the family’s children, and basically reduces the entire household to a broken heap of destruction and sorrow. Fifty years later, writer/director Sang-soo Im has decided this is material that bears a modern reevaluation.
