Ben Affleck was going to write, direct, and star in the hypothetical new Batman movie. Then he wasn't going to write it. Now he's not even going to direct it, but he'll probably still star in it (at least until he sees Zack Snyder's ridiculous new "even deadlier" Batmobile, because what the Caped Crusader really needed is more guns and missile launchers).
So, before Ben flees the madhouse that is the DC Cinematic Murderverse, let's take one last stab at getting him a plot, shall we? Namely, what do you do if you live in Gotham City (and are insanely rich)?
So, we just need to add on a Club Of Clubs, which you can join only by belonging to every other Gotham club...and someone is knocking the members off, one-by-one, as Bruce frantically tries to join every other club so he can get inside, and...
Once again, you see why I'm not allowed to write comic book movies.
