Instead, HBO Max is now working on a show set around Arkham Asylum, DC Comics’ home for all of Batman’s most mentally disturbed rogues.
It’s like a horror movie or a haunted house that is Arkham … the idea, again the way that Gotham is a character in the movie, I really want Arkham to exist as a character.
HBO Max didn’t like the idea of a show based on such a dark character, which is why Winter left the project in November of 2020.
Well before The Batman ever opened in movie theaters, Warner Bros. made it clear they had ambitious plans to create a multimedia universe out of the property.
