HBO Max already has a number of DC-related projects with others in the works, but it could do with some more major original programming. Tapping into the most popular DC character and building on an upcoming blockbuster movie seems like a solid choice. It’s unclear whether Pattinson will make any appearances in the show, but if he does, that might persuade some of his fans to sign up to HBO Max. In any case, it's a fairly safe bet that a show set in the world of The Batman will pull in some subscribers.
There’s no word as yet on when you can expect to start streaming this show. However, given that it’s in development, and most TV and movie productions are on hold amid the pandemic, we’re probably in for quite a wait. The Batman, meanwhile, will be released on October 1st, 2021.
