This is Michael Moore without the jokes - and without Moore's inflammatory stuff about the Bush-Saudi link. It's a dogged and fiercely unrelenting case against our military adventure in Iraq, composed of a sequence of talking-head observers, including former UN weapons inspector Scott Ritter. The points are repeatedly, even shrilly, hammered home. Right up to 9/11, the Bush administration said it had no interest in unseating Saddam. But after the WTC attack, and the subsequent failure to capture Osama bin Laden, regime-change in Iraq became fanatically promoted by a beady-eyed cabal of neo-cons: a consolatory, diversionary war built on a compost-heap of lies.

Director Robert Greenwald has come up with a documentary arguably lacking in elegance or entertainment value. Yet, frankly, the point of view in Greenwald's film bears stating, and re-stating, especially when our pro-war liberal classes seem so unmoved by the great political scandal of the age. Both Uncovered and The Corporation are strident, certainly. They may find pundits lamenting the absence of subtlety, of nuance, perhaps preferring some more restful fiddle music while Fallujah burns, or maybe no music at all. Yet aren't we impatient with guardedly ironic documentaries about the little things? These Americans are out there hunting big game. Why don't we Brits try something like that?
