Ben Affleck's Batman Movie Would Have Featured Arkham Asylum-Inspired Deathstroke Fight and DCEU Batgirl, Joe Manganiello Reveals

Joe Manganiello, who portrayed Slade Wilson (Deathstroke) in a now-canceled Ben Affleck Batman film, has revealed plot details in his new book, Bloodlines: A Memoir. The movie would have featured an Arkham Asylum-inspired fight scene with Deathstroke, as well as the debut of the DCEU's Batgirl. Manganiello explained that the narrative would have been a superhero version of David Fincher's The Game, focusing on Deathstroke's attempts to dismantle Batman's entire life.

The actor had previously shared this plot description but now provides additional details about Deathstroke's vendetta against Batman, which stemmed from believing Batman had murdered his son. The movie would have seen Deathstroke breaking into Bruce Wayne's Batcave and taking Alfred Pennyworth hostage. Another key plot point would have been the introduction of a new Batgirl, who would have joined Batman in a fierce fight against Deathstroke, narrowly escaping via an aboveground train.

The film was ultimately canceled, but Manganiello recalled feeling hopeful about working with Affleck, particularly praising his previous movies like The Town.
