Inside Ben Affleck's Canceled Batman: Deathstroke, Batgirl

Imagine a Batman movie designed as a slow, personal unravelling. Dark. Brutal. Close to home. That was Ben Affleck's plan — a version of Gotham where revenge isn't theatrical fluff but a surgical strike on Bruce Wayne's life.

The idea first leaked during Justice League's troubled shoot. Affleck posted a raw test clip of Deathstroke to social media while cameras rolled on Snyder's set, and Joe Manganiello had already been tapped to play Slade Wilson. Fans smelled a proper showdown: Batman versus Deathstroke. It felt inevitable.

In early cuts of Justice League, Lex Luthor — desperate and dangerous after Arkham — tells Deathstroke that Bruce Wayne is Batman. That reveal, briefly on screen, would have funneled straight into Affleck's solo film. Reshoots under Joss Whedon scrubbed that thread and nudged the universe toward other directions, leaving Affleck's blueprint stranded.

Joe Manganiello lays out the fuller picture in his new book, Bloodlines. According to him, Affleck wanted a superhero film that played like David Fincher's The Game: tense, paranoid, and intimate. Deathstroke's motive was stark. He believed Batman had killed his son. What followed was meant to be a campaign of ruin — not just against Bruce's mask, but against everything Bruce had built.

The proposed plot was unforgiving. Commissioner Gordon, played in the scheme by J.K. Simmons, would be killed. Alfred would be taken hostage after Deathstroke breached the Batcave. Midway through the script, a pitched fight almost ends with both Batman and a newly emerged Batgirl on the cusp of death — only for them to make a desperate escape aboard a passing train. Gordon's death, in this version, becomes the crucible that pushes Barbara Gordon into donning the cowl as Batgirl.

Affleck reportedly wanted the final confrontation to be a brutal, citywide melee — a bloodied duel through Gotham's streets inspired by the combat tone of Batman: Arkham Asylum. It wasn't to be ballet. It was meant to land like a fist. Manganiello remembers telling Affleck: 'I love your films — especially The Town — and I wanted to see a Batman from him that felt worthy of awards.' That sense of ambition threaded every beat of the canceled script.

But life intervened. Affleck stepped away, citing personal struggles and frustration with Justice League's retooling. Warner Bros. pivoted, hiring Matt Reeves to steer a different ship. Rumors suggested Affleck might still appear, yet the project ultimately rebirthed as a standalone story. Robert Pattinson now inhabits a Batman set in his second year on the job — a separate, less entwined timeline than Affleck's darker revenge cycle.

It leaves us wondering: what would a Ben Affleck Batman — equal parts crime drama and moral bloodletting — have looked like in theaters? The blueprint is out there, in pages and anecdotes. The film isn't. For now, it's another Gotham legend, whispered in corridors and fan forums, a cinematic path not taken.
