Matt Damon

Actor Matt Damon will quit playing assassin Jason Bourne after the third film, The Bourne Ultimatum, is released this summer.

Damon wants someone else to take on the role--created by author Robert Ludlum--and make it their own.

Speaking at the Cannes Film Festival, Damon says, "I'm definitely done with that. I think we've ridden that horse as far as we can.

"The character lives on in the books and if someone else wanted to play it, I guess they could."
