DVD: Green Zone (15)

Bourne is back, and he's better than ever. Well, not quite. This time, the Bourne Ultimatum duo – the director Paul Greengrass and star Matt Damon – have moved beyond their critically acclaimed franchise and teamed up to belt out a provocative and action-packed thriller.

Amid the chaos and deadly political intrigue of post-invasion Iraq, Chief Warrant Officer Roy Miller (Damon) leads an elite US Army team in search of Saddam's stock of weapons of mass destruction. But with his search proving fruitless (we wonder why...), he starts to ask tricky questions, teams up with a gruff CIA agent (Brendan Gleeson) and ventures off-grid to test his own theories. And soon, even factions within his side are out to kill him and send Iraq into a spiral of violence. Sadly, for such a well shot film, the plot, despite the best efforts of Greengrass and the enlisted screenwriting talent of Brian Helgeland (LA Confidential), lacks credibility and wanders off into true Hollywood naivety. But despite this, they do a pretty good job of turning the complex and shifting sands of post-war Iraq into stonking thriller and one of the best films to come out of the conflict – The Hurt Locker aside. And it's that Oscar-winning film's Barry Ackroyd who turns Green Zone into a potent work. It's his frantic editing that turns an already terrifying Baghdad into a fast-paced nightmare of firefights and fear.
