War of the Buttons
La Guerre des boutons or War of the Buttons is a 1962 French film directed by Yves Robert. War of the Buttons is about two rival kid gangs whose playful combats escalate into violence. The title derives from the buttons that are cut off from the rival team's clothes as combat trophies. The film is based on "La Guerre des boutons", a novel by Louis Pergaud (1882–1915), who was killed in action in World War I and whose works portray a fervent anti-militarism.
