Bourne Ultimatum Trailer

Continuing the story of Jason Bourne, a man without an identity, this third installment picks up with Jason being hunted by the same people who have made him what he is. Having lost his memory and the one person he loves, Bourne weathers a hail storm of bullets and a whole new barrage of highly paid killers to reach The Bourne Ultimatum. Hunting down his past to find a future, Bourne must travel from Moscow, Paris, Madrid and London to Tangier and New York City--all while trying to outmaneuver the scores of cops, federal officers and Interpol agents with him in their crosshairs.

The Bourne Ultimatum opens in theaters on August 3, insuring a steamy, sweat-soaked summer. Paul Greengrass (United 93) directs all the action and thrills. His cast includes Matt Damon, Julia Stiles, Joan Allen, David Strathairn, Paddy Considine and Edgar Ramirez.
