John C. Reilly has come aboard Roman Polanski's latest drama God of Carnage. The actor will join the Oscar-winning cast of Kate Winslet, Jodie Foster, and Christoph Waltz in this look at parenting and playground warfare.

Matt Dillon had previously been attached to play Michael, the role that John C. Reilly is now taking over. Deadline reports that actor James Gandolfini originated the role of Michael onstage.

Adapted from Yasmina Reva's play of the same name, the script will revolve around two sets of parents who get into an argument after their children are involved in a playground scuffle. Jodie Foster will be playing John C. Reilly's wife.
