Marshall told IESB on the red carpet of the Saturn Awards that Bourne 4, as it's being called, will "absolutely" happen. Since the fourth book, titled The Bourne Legacy, was written by Eric Van Lustbader instead of Ludlum because he was no longer alive at the time, they're going to go down their own path. "We're probably going to take our own direction and we're working on what that storyline's gonna be right now." As for where Bourne might be going to this time, since he already made it all the way back to New York City - South America. Marshall says that they'll probably take him "down south" to South America in the fourth installment, but story details aren't fully finished yet.
