Yasmina Reza’s Tony-winning play “God of Carnage” doesn’t inherently lend itself to cinema. With four characters interacting in a single setting, and a narrative centered on a thin symbolic conceit, it’s the sort of dialogue-heavy project that could easily be captured with a tedious cut-and-dry, shot-reverse-shot filmic approach. It’s fortunate, then, that Roman Polanski has taken it on in Carnage, and filled the roles with some of the most interesting actors around. Say what you will about Polanski the man, but Polanski the filmmaker has demonstrated an almost limitless aptitude for creative technique. Similarly, Jodie Foster, John C. Reilly, Kate Winslet and Christoph Waltz (four Oscar wins among them) have a preternatural gift for imbuing even the quietest moments with extraordinary, unconventional feeling. After young Zachary Cowan hits Ethan Longstreet with a stick during a playground brawl, knocking out two of Ethan’s teeth, the latter’s parents invite the former’s to their Brooklyn apartment to discuss the incident. Over the course of a tumultuous morning, Penelope and Michael Longstreet (Foster and Reilly) and Nancy and Alan Cowan (Winslet and Waltz) will spar, commiserate and touch on the essence of parenthood, manhood and the art of confronting modernity with a social conscience.
