One lesson to learn is that the press and the broadcasters are not neutral. And it seems we have to learn it each time there is a dispute: they are actually committed to one side.

No political politicians on the board and stop sub-contracting anyway, which means getting out of Iraq. If anything needs to be policed, it needs to be done through a proper international body... not through us sub-contracting teams of mercenaries.

You'll get unsociable people whatever the nationality, colour, race or creed. I guess the British abroad have probably got the worst record of anyone.

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.

The duty of a film director is to focus more on the soul of the spectator.

Shaping it is something I would expect to do together with a writer, because that's a director's job.

The most depressing thing is the political slogan: there is no alternative. But there is.
