The Bourne films are a series of American action films based on the character Jason Bourne, a CIA assassin suffering from dissociative amnesia who must figure out who he is, created by author Robert Ludlum.
All three of Ludlum's novels were adapted for the screen, featuring Matt Damon as the title character in each. Doug Liman directed The Bourne Identity (2002) and Paul Greengrass directed The Bourne Supremacy (2004), The Bourne Ultimatum (2007) and Jason Bourne (2016). Tony Gilroy co-wrote each film except for Jason Bourne and directed The Bourne Legacy (2012).
Damon chose not to return for the fourth film, The Bourne Legacy, which introduces a new main character, Aaron Cross (Jeremy Renner), a Department of Defense operative who runs for his life because of Bourne's actions in Ultimatum. The character of Jason Bourne does not appear in Legacy, but mention of his name and pictures of Damon as Bourne are shown throughout the film. Damon returned for the fifth installment, Jason Bourne.
The Bourne series has received generally positive critical reception and grossed over $1.6 billion. Like many action series, it is distinguished by its use of real stunt work, in contrast to the growing use of computer-generated imagery in action scenes.
