Roman Polanski is ready to unveil his big screen adaptation of the hit Broadway play God of Carnage, simply titled Carnage. From the looks of the first trailer below, stars Jodie Foster, Kate Winslet, John C. Reilly and Christoph Waltz are more than up for this witty, nasty tale of two sets of parents at war. Carnage premieres at the 2011 New York Film Festival on September 30.
