Summary
Ben Affleck never made a soloBatmanmovie in theDCEU, although an animated Arkham film released in 2014 comes close to what the filmmaker had planned. Following the actor’s casting inthe DCEU timelineas Bruce Wayne inBatman v Superman: Dawn of Justice,Ben Affleck’s celebrated careerseemed to be leading to his directing and starring in a Batman film. Details surrounding the picture are inconclusive, but what is known is that it was intended to be calledThe Batman, that Joe Manganiello was set to play the villain, and that it would take place in Arkham Asylum.
Arkham Asylum has been an essential part of Batman lore, appearing most recently in Matt Reeves’The Batmanfilmseries that replaced Ben Affleck’s. This iteration is receiving its ownArkham AsylumTV spin-off, but until then,Arkham Asylum has mostly been an intermittently featured location in the series and not a place for extended storytelling. There are two exceptions to this: the first being theArkhamseries of Batman video games, and the second being an animated spin-off of those games.

WithSuicide Squadpreceding its release, the possibility of Harley Quinn and Captain Boomerang making an appearance in the Affleck film, just as they did inBatman: Assault on Arkham, seemed likely.
