The Batman direct Matt Reeves is actively developing a TV spinoff about the Gotham City Police Department at HBO Max. The series will be overseen by Reeves and Boardwalk Empire’s Terrence Winter. It will be set in the movie universe with the intent to expand it across multiple platforms.
Winter’s previous work on The Sopranos and The Wolf Of Wall Street seems to imply a grounded and gritty tone for the series. It’s possible that the series will pull influence from Gotham Central, the comic books series that focused on the difficulties the Gotham City Police Department faced living in the same city as Batman. It was written by Ed Brubaker and Greg Rucka, with pencils initially by Michael Lark.
The Batman is set to release on October 1, 2021.
