All four films in the espionage thriller franchise based on the Jason Bourne novels by Robert Ludlum. In the first film, 'The Bourne Identity' (2002), CIA assassin Bourne (Matt Damon) is pulled out of the Mediterranean by fishermen, badly wounded and suffering from amnesia. Unable to recall either who he is or what has happened to him, the only clue to his identity is the number of a Swiss bank account which has been etched into a device implanted in his body. Following the lead to Zurich, he discovers money, passports and a gun waiting for him, but also earns the attention of the security services. He then persuades a young woman named Marie Kreutz (Franka Potente) to drive him to Paris, where he hopes to find out his true identity and discover the reason why the CIA are taking such an interest in him. In the second instalment, 'The Bourne Supremacy' (2004), Bourne has left his violent past behind him and is living a normal life with girlfriend Marie under an assumed name. But his plans for a peaceful life are crushed when he narrowly escapes an assassination attempt. Now hunted by an unknown enemy, Bourne must prove that he is not an easy target. In 'The Bourne Ultimatum' (2007) Bourne races to uncover the dark mysteries of his past while a government agent is hot on his trail following a shoot-out in Moscow. Finally, 'The Bourne Legacy' (2012) moves away from the central character in the previous films to focus on a new protagonist, CIA operative Aaron Cross (Jeremy Renner). The story, which takes up events where 'The Bourne Ultimatum' left off, sees Cross making the vow to give himself over completely to 'the operation', quickly proving himself to be the shining star in a new generation of deadly undercover assassins.
