Developed by Matt Reeves & Terence Winter (Boardwalk Empire/The Sopranos)
The series does not yet have a title, although some have been calling it Gotham Central, harkening back to the police procedural comic from writers Ed Brubaker and Greg Rucka, and GCPD. Either way, it would deal with police detectives working in the shadow of one very batlike vigilante.

HBO Max says the series will be "set in the world Reeves is creating for The Batman feature film and will build upon the motion picture’s examination of the anatomy of corruption in Gotham City, ultimately launching a new Batman universe across multiple platforms. The series provides an unprecedented opportunity to extend the world established in the movie and further explore the myriad of compelling and complex characters of Gotham."

"You start to see the story from the point of view of these corrupt cops, one in particular," Reeves told fans. "The Gotham PD series will go into the corruption of the Gotham Police Department...it goes back to Batman Year One...we'll see these characters from a perspective we've never seen before."
