Directed by Roman Polanski and starring Jodie Foster, Kate Winslet, Christoph Waltz, John C. Reilly, CARNAGE is a razor sharp, biting comedy centered on parental differences. After two boys duke it out on a playground, the parents of the “victim” invite the parents of the “bully” over to work out their issues. A polite discussion of childrearing soon escalates into verbal warfare, with all four parents revealing their true colors. None of them will escape the carnage. 1 hr 20 mins, rated R
