The Iraq war is a huge subject and there have been many films about it. But it was when the private contractors started taking over and taking responsibilities from the regular army, which hides the war. You have these private armies of mercenaries acting with immunity for their actions, the worst of which was the Blackwater case where they killed 17 Iraqi civilians and the guys who did it just went home. We [screenwriter Paul Laverty and Loach] felt this deserved a story.
