Universal released the info in a release about their upcoming slate of films, and according to them both Damon and Greengrass are definitely returning to work together on the spy franchise. There are two books left in the Bourne series, so at least there would be some source material to start with. The two are currently working on the Iraq drama, The Green Zone, and Damon has already signed to star in The Informant for Steven Soderberg and is also in talks to star in The Human Factor for Clint Eastwood. Greengrass is also going to be busy with his upcoming Vietnam drama, They Marched into Sunlight. So it could be as late as 2010, before the two can even get started on making another Bourne flick, let alone get one into the theaters. However, with Bourne Ultimatum taking home three Oscars last night (three!), I imagine the fourth flick might be made a priority. For Universal's sake, I hope this one is a done deal. I can't help but think how embarrassing it must have been for MGM's Harry Sloan when his studio got a little overzealous about a certain spy franchise.
