Ben Affleck has been putting so much work into assuring us that he’ll be back to play Batman. In classic little-brother fashion, however, Casey Affleck might have just leaked the news that Batfleck will end with Justice League. When Casey appeared on WEEI’s “Dale & Holley With Keefe†radio program to talk about throwing the first pitch at Fenway Park, the hosts praised Ben’s Batman performance, and asked if he’d be back. Instead of coyly demurring — or even just saying he didn’t know — Casey said that Bafleck wouldn’t be back, then awkwardly backpedaled. “Um … I thought he was an okay Batman. As far as … Nah, he was great,†Casey joked. “He’s a hero, so he had something to channel and work with there. But he’s not going to do that movie, I don’t think.†Oof! Ignoring all the signs, the hosts seemed to be shocked, then Casey tries to clean it up: “Is that breaking news? I was kind of making that up?†Oh, to be in the Ben–Casey–Matt Damon group text right now.
