First announced in July last year , the still-untitled Gotham-focused was pitched as a spin-off series to Matt Reeves’ The Batman , which would explore the corruption of Gotham City and the police who fight and participate in it. Initially announced to be written and produced by Terrence Winter, who created Boardwalk Empire and worked on The Sopranos , the series needed to find its footing after Winter left the project due to creative differences with Matt Reeves and other producers.
This spin-off is one of many DC properties being turned into a series for HBO Max, joining the likes of James Gunn's Peacemaker , Seth Grahame-Smith and Marc Guggenheim's Green Lantern series , and possibly more . Warner Bros. was able to find a replacement for Winter in a timely manner with a filmmaker whose vision hopefully won't clash with Reeves' and the rest of the executives.
Variety has reported that Joe Barton will be the new showrunner for the upcoming Gotham PD series at HBO Max following Terence Winter's departure in November. This show will exist as a spin-off within the same universe as Matt Reeves' The Batman, starring Robert Pattinson.
Barton will also serve as an executive producer on the Gotham-focused series.
WHAT THIS MEANS
Joe Barton has quite an interesting catalog, having written works like Giri/Haji , a crime-drama about a detective looking for his missing brother, and The Ritual , an intense horror movie exploring guilt. It's a no-brainer why Barton was likely chosen to head up this spin-off series, already having experience writing crime and corruption in the underworld and police, but also adapting works like Adam Nevill's The Ritual .
It will be interesting to see how much of the Batman mythos that isn't nearly as grounded makes its way into this series. Matt Reeves' has said that his Batman is still relatively new, having only fought crime for over a year now with his villains not having fully come into their own quite yet, so it's not like Gotham policeman will be fighting established Batman foes like Poison Ivy or Scarecrow. It should still be a unique perspective to explore, seeing how civilians and officers respond to Batman and how he slowly changes Gotham, for the better or worse.
