The fourth outing in the popular espionage action thriller franchise based on the Jason Bourne novels by Robert Ludlum. Written and directed by Tony Gilroy, who scripted the first three films, the film moves away from the central Bourne character (played in the opening trilogy by Matt Damon) to focus on a new protagonist, CIA operative Aaron Cross (Jeremy Renner). The film, which takes up events where 'The Bourne Ultimatum' left off, sees Cross making the vow to give himself over completely to 'the operation', and quickly proving himself to be the shining star in a new generation of deadly undercover assassins. Rachel Weisz and Edward Norton co-star, while pivotal roles from the previous films are reprised by Joan Allen, David Strathairn, Albert Finney and Scott Glenn.
