Matt Damon admitted that ther could be a prequel to the action flick before untitled “Bourne 4″ project is made in a next few years.

“There’ll probably be a prequel of some kind with another actor and another director before we do another one,” Damon told Empire at the U.K. premiere of “Invictus”. “Just because I think we’re probably another five years away from doing it – we’ve got to get a script.” He then jokingly added, “If you have any ideas, call Universal. They’d love for you to get in touch!”

Paul Greengrass who worked on “Bourne Supremacy” and “Bourne Ultimatum” left the project in December 2009. He explained: “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.”

Matt Damon, beliving that Greengrass will return to “Bourne 4″, once said: “I’ll just wait for him and when he wants to do one, we’ll do it. I think it will happen down the road. We just don’t have a script right now.”
