Matt Damon and Ben Affleck are best friends, and just because they are Hollywood A-listers doesn’t mean they don’t know how to take a joke!

In an appearance on “Popcorn with Peter Travers,” Ben totally called out his best friend and Good Will Hunting co-writer on his jealousy. Apparently, Matt really really wanted to play Batman.

“He’s very bitter,” Affleck joked. “All he gets to do is Jason Bourne. Just keeps doing it again and again. We get it… I don’t think we’ve changed that much. Last night he emailed me and said, ‘You wanna come over and watch Monday Night Football. Being friends and having a guy to go through all that stuff with. To have a relationship and have a sense of humor about it, it’s crucial.”

Affleck is coming back as Batman in Justice League.
