Matt Damon has revealed he "would love" to return to the Bourne franchise.
The 42-year-old admitted he would consider reprising his role as agent Jason Bourne for a fifth instalment because he likes playing the character, but it would depend on director Paul Greengrass, who directed the first three films.
I would love to do another one. I love that character," he told Deadline.com.
"To me, the reason to make that movie is because people want to see it. Paul and I have said that to each other. We don't take for granted the fact that we've built an audience for Bourne, that's a real privilege.
"Neither of us is against it. "But our part of that bargain is that the movie is good and belongs with the other three. Until we can deliver that, we just can't make it."
Matt - who next stars in drama Promised Land with John Krasinski - has even enlisted The Dark Knight screenwriter Jonathan "Jonah" Nolan to cast a fresh eye on the films.
"I quietly went to Jonah Nolan, because he and his brother Chris did such a brilliant job on Batman and that whole mythology. I just said, can you put your brain on this? I can't figure it out," he recalled.
"He took a run at it and he couldn't crack it either. Paul and I have been talking about it for years. And we can't quite see what the movie would be."
