The Bourne Ultimatum is a 2007 action-thriller film directed by Paul Greengrass. Although it shares its name with the 1990 novel The Bourne Ultimatum by Robert Ludlum, its plot is entirely different. The screenplay was written by Tony Gilroy, Scott Z. Burns and George Nolfi and based on a screen story of the novel by Gilroy. The Bourne Ultimatum is the third installment in the Jason Bourne film series, after The Bourne Identity (2002) and The Bourne Supremacy (2004).
