The Batman might not be a part of the DC Extended Universe, but it's birthing a cinematic universe. Even before the Matt Reeves film premiered, HBO Max had confirmed at least two spin-offs with a Catwoman series in consideration as well. The first one, GCPD, is reportedly a drama set a year before the events of The Batman, just as the caped crusader started his life-long vigilante career. Meanwhile, the second spinoff will star Colin Farrell's Oswald Cobblepot, in a story revolving around his life as one of Gotham's criminal under lords. Now, it appears that another spin-off is coming featuring the deranged patients of Arkham Asylum.
Reeves recently sat down with the Toronto Sun to talk more about the Farrell-led The Penguin series on HBO Max. In the middle of the interview, Reeves also brought up an interesting update on other The Batman spin-offs. In particular, Reeves revealed that he's working on a show about Arkham Asylum, which caught the attention of fans.
The infamous institution is an integral part of Batman lore. The first two games of Rocksteady Studios' critically acclaimed Batman: Arkham trilogy were set in the said psychiatric prison. Throughout the years, the hospital has housed some of Gotham's worst criminal minds such as Batman's rival, the Joker. In most stories, the Asylum is also is where Harleen Quinzel initially worked as a psychiatrist before falling in love with Joker and becoming Harley Quinn.
