Ben Affleck's tenure as Batman seems to have come to a close, but we now have some idea of the tone and content of his abandoned Batman movie. According to cinematographer Robert Richardson, Affleck's version of The Batman would have explored Batman's grip on sanity and focused on Arkham Asylum.

Richardson was previously attached to The Batman when Affleck was still slated to direct and star, and he shed more light on that version of the film on an episode of Josh Horowitz’s Happy Sad Confused podcast (via Batman News )."Well, he was going more into the insanity aspects," said Richardson. "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. 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."Sadly, we'll most likely never see this Arkham-centric Batman movie on the big screen. Affleck confirmed his exit in March , telling Jimmy Kimmel, "I tried to direct a version of it, and worked with a really good screenwriter but just kinda couldn’t come up with a version… that couldn’t crack it, and so I thought it was like, you know, time to let someone else take a shot at it. They got some really good people, so I’m excited."Instead, The Batman will be directed by Matt Reeves and feature Robert Pattinson taking over the iconic role . War for the Planet of the Apes star Andy Serkis is also rumored to play an unspecified role . The film will reportedly be set in the '90s and kick off a new Batman trilogy . Rumors point to a large cast of villains that includes Penguin, Catwoman, Riddler, Two-Face and Mad Hatter.For more on this upcoming reboot, here's everything we know so far about The Batman
