Oscar-winner Ben Affleck was at one point attached to write, direct, and star in an all-new Batman movie. However, the actor eventually dropped out, and Matt Reeves came in to direct and write a new script. But what was Affleck’s Batman movie going to be about?

Robert Richardson, who was set to be the cinematographer on Affleck’s movie, said on the Happy Sad Confused podcast that the Batman flick would have delved into "the insanity aspects."

"Well, he was going more into the insanity aspects. So I think you would’ve seen something a little darker than what we’ve seen in the past and more into the individual, who’s inside Batman," Richardson said, via Batman-News. "What element may be sane and what element may actually not be sane. So he was entering into a little more of the Arkham, as you know, he’s going into where you keep everyone who was bad, everyone that shifted and Batman."

Richardson said it was "very fascinating" to visit the darker side of Batman. Another interesting element is that Arkham Asylum is rarely seen in Batman movies, though Rocksteady’s Batman: Arkham Asylum is set there. The new Joker movie starring Joaquin Phoenix will see the character visiting the "Arkham Hospital."

Robert Pattinson stars in the new Batman as the caped crusader in the film that’s due in theatres in June 2021. The movie has been in the works for several years; Affleck stepped down as director in early 2017, and more recently confirmed that he was no longer involved at all, stating that he had "tried to direct a version of it, but couldn’t crack it."
