“Here piggy, piggy!” From a bondage-clad Emmanuelle Seigner whipping her asshole of a husband Peter Coyote, while he writhes around on the floor in a porcine mask, to an uptight Kristin Scott Thomas lezzing off on the dancefloor on a depressing New Year's Eve cruise, as a bereft Hugh Grant looks on, Roman Polanski’s erotic thriller is basically just a study of how power works in relationships, but with potentially more drastic consequences like maiming and murder.
