Warner Bros. reportedly got over 50,000 protest letters back in the eighties when Michael Keaton was cast as Batman. Now, Ben Affleck appears on his way to accomplishing a similar feat. Except instead of sending letters, Ben Affleck casting protestors are signing online petitions.
A change.org petition to have Warner Brothers remove Ben Affleck as Batman/Bruce Wayne in the Superman/Batman movie has gotten a lot of media coverage today, which has likely been a big part of driving signatures from well under 10,000 to now over 25,000 signatures.
In regards to Ben Affleck, the petition states: "His acting skill is not even close to being believable as Bruce Wayne and he won't do the role justice. He's not built, nor is he intimidating enough for the role of Batman. His portrayal of Daredevil was atrocious and he's not remotely close to an action star. Please find someone else. "
