The 45-year-old "Jason Bourne" star said he loved Affleck's superhero and he would do anything for his friend, reported Digital Spy.
"I thought Ben did a great job and I really liked the way that he played the character. It felt like this kind of older... This Bruce Wayne who had, you know, kind of carried the darkness with him a little bit and lived through a lot and I thought he did a great job.
"Jason Bourne was always kind of my superhero, so I kind of have that out of my system. If he (Affleck) had a part for me, yeah. I'd do anything with him!" Damon said.
