Producer Frank Marshall recently told MTV that he doesn't expect the upcoming "The Bourne Ultimatum" to be the last film in the highly successful spy series.
"It's kinda up to Matt [Damon]. Maybe to five [films] ... At some point, he's gotta find out who he is" says Marshall who added about 'Ultimatum' that Julia Stiles' character will "be a central character in this. So will Joan Allen and some of the other characters from the last movie"
The third film is scheduled to start shooting on August 1st and whilst the title is the same as the Robert Ludlum book, only the first film in the series bares any real resemblence to the original novel.
Writers therefore will have to come up with storylines for future sequels, though it seems likely a fourth 'Bourne' will use the title "The Bourne Legacy" after the recent Eric Van Lustbader novel which continues Ludlum's trilogy. "Ultimatum" will be directed by Paul Greengrass and is expected to hit theaters in the summer of 2007.
