DAMON SIGNS ON TO THE BOURNE ULTIMATUMHollywood actor MATT DAMON has confirmed he's signed up for a second sequel to THE BOURNE IDENTITY - but will happily drop out of the project if the script is anything less than brilliant.Damon played spy JASON BOURNE in The Bourne Identity and its follow-up THE BOURNE SUPREMACY, and is ready to go to work on third film THE BOURNE ULTIMATUM should a decent screenplay be written.He tells website EMPIREONLINE.COM, "We'll probably do that in about a year and a half. We're all signed on in principle, in the sense that we've all agreed that we want to do it, but we're not going to do it unless we h ave a great script."If we do make a third one, we want to make it as good as the first two. And if we can't do that, then we're going to have to let it drop."
