"Bourne" to Go on a Fourth Adventure?

Matt Damon and director Paul Greengrass ("The Bourne Supremacy," "The Bourne Ultimatum") were recently asked about the future of the "Bourne" series.

Matt Damon seemed enthusiastic about the future:

"We’ve just kind of been amused by the whole thing," said Matt Damon about rumors of a fourth film. "I think it’s one of these stories that has a life of it’s own. Not that we’re against it, we’re all for doing a fourth movie but it means coming up with a good story. There are a lot of things that would have to happen before we would sign up for it."

Paul Greengrass seemed surprised when Damon basically admitted he'd be up for another:

"He says yes? It’s news to me. I think the truth is that it’s a very well loved franchise, but we’re in the process of trying to work out what kind of film you could make. If there is one, what would it be? How it could go? Without any pressure; without any commitment to it, but everybody loved the franchise. We love it, but none of us would want to go again unless we’re sure there’s a worthwhile film and that could take some time. You don’t want to do that when you feel like you’ve got to make it and none of us need to, so that’s where we are."

So I guess another "Bourne" flick is a little ways off and I don't think anyone's jumping at getting another one done right now. But the fact that there's this much buzz about it leaves me hopeful.
