It looks like you can't keep a good spy dead, as Variety has word that Universal are moving ahead with a fourth installment of "The Bourne Identity" series, hiring co-writer of the third film, George Nolfi to pen the script.
Though the series is based on the Robert Ludlum novels, the new film won't be based on a Ludlum title, but rather an original story. Paul Greengrass and Matt Damon are expected to return aswell so this should be a cracker.
