The Bourne Legacy

In The Bourne Legacy, Aaron Cross, a member of a black ops program whose agents are genetically enhanced, goes on the run once Bourne's actions lead to the public exposure of Operations Treadstone and Blackbriar. It is the fourth installment in the Bourne film series, which is based on Robert Ludlum's Jason Bourne series. Titular character Jason Bourne does not appear in The Bourne Legacy, as actor Matt Damon, who played Bourne in the first three films, chose not to return for a fourth film. Gilroy, co-screenwriter of the first three films, sought to continue the story of the film series without changing its events, and parts of The Bourne Legacy take place at the same time as the previous film The Bourne Ultimatum (2007).
