Roman Polanski is lining up a terrific cast for his adaptation of Yasmina Reza's Tony-winning play God of Carnage.  Deadline reports that Jodie Foster, Kate Winslet, Christoph Waltz, and Matt Dillon have signed on to star in the drama.  Per Deadline, "God of Carnage tells the story of two sets of parents who meet after their sons are involved in a schoolyard fight. The meeting goes disastrously wrong as each pair attacks the other’s parenting skills before turning on each other about problems in their own marriages."  Remember kids: if you get into fight in the schoolyard, you're probably going to break up your parents.

Foster is currently in the unenviable position of defending Mel Gibson as he stars in her first directorial feature in 15 years, The Beaver.  Winslet will next be seen in Steven Soderbergh's Contagion and the HBO miniseries Mildred Pierce.  Waltz is currently shooting on Paul W.S. Anderson's The Three Musketeers and will next be seen in Michel Gondry's The Green Hornet and Francis Lawrence's Water for Elephants.  Dillon most recently co-starred in Takers.
