Cinematographer Robert Richardson, who was attached to The Batman in that earlier iteration, also revealed that the movie would have seen the masked Bruce Wayne exploring Arkham Asylum.
Taking place after the events of Justice League, the original plan for The Batman was for the eponymous protagonist to face off against Slade Wilson, a.k.a.
Joe Manganiello was cast as the one-eyed assassin, and he cameoed in Justice League’s end-credits scene.
