Paul Greengrass has confirmed the rumours that he has left the Bourne franchise.
Despite The Bourne Ultimatum being the final movie in the trilogy rumours of a fourth movie have circulated for months, with both Greengrass and actor Matt Damon attached to the project.
Greengrass claimed that he wanted a 'different challenge' and played down rumours of a fall out with Universal Pictures over the script and budget.
In an interview with Variety the filmmaker said: "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."
However he will team up with Matt Damon next year with the release of war movie The Green Zone.
No one has yet been named as his replacement.
