Ben Affleck's brother Casey may have revealed something huge for the upcoming Warner Brother's release of The Batman

Casey revealed that he doesn't think his brother is going to have a role in the upcoming release. Ben Affleck has always been on the fence about doing another Batman movie saying, "If we start doing it, and I don't like the way it's coming out, I'm not afraid to back out". However, at Comic-Con International: San Diego 2017, Ben came out and said he was definitely working on the movie. However, his role was not confirmed. 

Ben Affleck is definitely going to be Batman in the upcoming release of Justice League, but it is looking doubtful that he will star in another solo film. 

Ben and Casey Affleck have repeatedly worked together on films, whether it is writing or directing. They stay in constant communication about what they are working on which makes these rumors that much more believable, not to mention they are brothers!
