You won’t find a more devoted supporter of the Bourne franchise than me. I will always be grateful to have been the caretaker to Jason Bourne over the course of The Bourne Supremacy and The Bourne Ultimatum. I’m very proud of those films and feel they express everything I most passionately believe about the possibility of making quality movies in the mainstream. My decision to not return a third time as director is simply about feeling the call for a different challenge. There’s been no disagreement with Universal Pictures. The opportunity to work with the Bourne family again is a difficult thing to pass up, but we have discussed this together and they have been incredibly understanding and supportive. I’ve been lucky enough to have made four films for Universal, and our relationship continues. Jason Bourne existed before me and will continue, and I hope to remain involved in some capacity as the series moves on.
Now whether you think that’s just a long-winded way of saying “creative differences” or that Greengrass is making sure not to burn a bridge or if this is the straight dope, the truth still remains that whenever we see the 4th Jason Bourne movie, it won’t have Paul Greengrass as its director. Now the question becomes if Greengrass’ departure means Matt Damon, whose loyalty lies with his director, will still return.
