The Playlist is reporting that director Paul Greengrass has left the production of the fourth Jason Bourne film, which is currently in development at Universal Pictures.

It was said that there are currently two scripts for the project, one by The Bourne Ultimatum co-writer George Nolfi and another by Josh Zemuter. It seems that no one cares much for Nolfi's script and Greengrass wasn't happy when Zemuter was hired without consulting with him first. Greengrass is currently working on post-production of his latest film with star Matt Damon, The Green Zone, which was said to be in a bit of trouble itself with the budget escalating to $150 million, from its original $100 million budget.
