Carnage

When two grade-school boys get into a fight in the park that results in one boy, Zachary Cowan, hitting the other, Ethan Longstreet, in the face with a stick, their parents meet in a Brooklyn apartment to discuss the matter. Zachary's parents, Alan (Christoph Waltz) and Nancy Cowan (Kate Winslet), visit the home of Michael (John C. Reilly) and Penelope Longstreet (Jodie Foster), Ethan's parents. Their meeting is initially intended to be short, but due to various circumstances, the conversation continues to draw out.
