When their sons are involved in a playground fight, corporate power couple the Cowans (Christoph Waltz and Kate Winslet) are invited to the Brookyln apartment of arty do-gooders the Longstreets (John C. Reilly and Jodie Foster) to talk through the incident. They hope to resolve it amicably; after all, they're 'decent people', right? Wrong. What follows is a hysterically funny and agonisingly tense descent into some very enjoyable bad behaviour as all four reveal their true colours amid a blur of whisky, cobbler, telephones, a hamster, and some astonishingly violent vomiting. Filmed with Polanski's trademark claustrophobic touch, this is a snappy, tremendously acted and brilliantly sustained expose of liberal hypocrisy.
