The titular character Jason Bourne does not appear in The Bourne Legacy, because actor Matt Damon chose not to return for the fourth film, due to Paul Greengrass not directing. Bourne is shown in pictures and mentioned by name several times throughout the film. Tony Gilroy, co-screenwriter of the first three films, sought to continue the story of the film series without changing its key events, and parts of The Bourne Legacy take place at the same time as the previous film, The Bourne Ultimatum (2007).
