The Bourne Ultimatum is a 2007 action-thriller film directed by Paul Greengrass. Although it shares its name with Ludlum's titular 1990 novel, its plot is entirely different. The third installment in the Jason Bourne film series after The Bourne Identity (2002) and The Bourne Supremacy (2004), the screenplay was written by Tony Gilroy, Scott Z. Burns and George Nolfi and based on a screen story of the novel written by Gilroy. Matt Damon reprises his role as Ludlum's signature character, former CIA assassin and psychogenic amnesiac Jason Bourne.
