"Extra's" Renee Bargh was at the premiere of "Jason Bourne" in Las Vegas catching up with the movie's star, Matt Damon. Matt chatted about "Bourne" and whether or not his children think he's an action hero in real-life since he plays one in the film. Since Matt's buddy Ben Affleck recently donned the cape and cowl to play Batman, Renee had to ask Matt which on-screen hero would win in a fight, Batman or Jason Bourne? Watch his hilarious response!
