This fall, Max's original series The Penguin will help bridge the gap between The Batman and The Batman Part II. However, the second planned spin-off series centered on Arkham Asylum is no longer going forward at Max.

Via Variety, Arkham Asylum was intended to be Max's second series in The Batman's continuity. Antonio Campos was previously attached to Arkham Asylum as the writer and the showrunner in 2022. But after two years of development, Max has elected to not go forward with Campos' version of the show. While the outlet notes that a separate Arkham Asylum series could eventually go forward at Max, the show as originally conceived is dead for now.

Before the second spin-off from The Batman was centered on Arkham Asylum, it was originally announced as a show that would focus on the Gotham City Police Department. In 2020, Boardwalk Empire creator Terrence Winter was signed to write and executive produce the series before he left the project over creative differences. Winter's successor, Joe Barton, also left the spin-off for the same reason.
