Let’s hope Matt Damon and Jeremy Renner don’t bump into each other at a restaurant. In re-engaging with Universal to return to the Jason Bourne franchise with director Paul Greengrass after their contentious exit following 2007’s The Bourne Ultimatum, Damon has put in jeopardy a planned follow-up to 2012’s The Bourne Legacy that is set to star Renner and be directed by Justin Lin for a 2016 release. Several sources say that if deals and a story idea can be worked out with Damon and Greengrass — no small feat considering both bailed over Greengrass’ creative issues — Universal will proceed with a Bourne reunion and put the Renner reboot follow-up on the back burner. Damon’s return for a fourth Bourne likely would be a boost for him and for the franchise. His third outing grossed $442.8 million worldwide and generated strong reviews.
