One series will be about Oswald Cobblepot aka The Penguin and the other one is believed to be a police procedural series, unofficially titled Gotham Central.
The Batman has been released in theatres all over the world and has been getting raving reviews. The DC Extended Universe, in particular, that of Batman is set to expand further. In addition to the two planned sequels to the movie, there are also two spin-off television series in development for HBO Max.
Director Matt Reeves has shared what is in store for the spin-offs. Speaking to the Toronto Sun he has shared details that the series will focus on Colin Farrell's Oswald Cobblepot aka The Penguin, the other one is believed to be a police procedural series, unofficially titled Gotham Central.
"We’re doing [The Penguin series] and we’re doing another series that connects to Arkham [Asylum]," Reeves said, adding, "This is the beginning of this world and there are all these places we can go with these characters. And with this cast that came and brought such vivid life [to it]." He went on to say, "Colin Farrell (who plays Penguin in The Batman movie) is like you've never [seen]. He's incredible and he actually is sort of a scene-stealer because he's just so funny, he's just so great. Along the way, we thought, 'Oh, well maybe we can do this as a series.'"
Reeves then shared that he discussed with HBO Max, and "showed them Colin in the movie and I talked to them about what this could be. And they were like, 'Let's do that.' So we're doing that and we're doing another series that connects to Arkham." While he did not elaborate on the other TV series, way back in 2020, The Hollywood Reporter noted that the show would 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."
The goal is to ultimately launch a new Batman universe across multiple platforms. HBO Max stated that the series will provide an "unprecedented opportunity to extend the world established in the movie and further explore the myriad of compelling and complex characters of Gotham." Kevin Reilly, HBO Max chief content officer, had stated at the time, "Our collaboration with Warner Bros. and DC allows us to elaborate and grow fan connections across these powerful brands for years to come. This is Batman as most audiences have never seen before, and we know fans will want to spend more time in this new world inspired by the film."
As for the sequel films Reeves said, "We are talking and thinking about the next movie, but to be honest with you, at the moment, I really want the audience to connect with this. And I really believe they will because I think Rob is an incredible Batman."
