Cameras started rolling on Batgirl last month, and Warner Bros. has now shared an updated cast list and brief synopsis which lists a surprising new addition to the ensemble.
If this is accurate, it looks like Michael Keaton's Batman will have a role to play in the upcoming HBO Max feature after first appearing in The Flash. We had previously heard that Andy Muschietti's film would set-up the events of Batgirl, so this wouldn't be entirely out of the blue - though it is somewhat surprising that such a major casting announcement didn't come via the trades. This may also confirm reports that Keaton's take on the Dark Knight will be the main DCEU's Batman moving forward.
Will this older Bruce Wayne serve as a mentor to Leslie Grace's Barbara Gordon, perhaps?
In related news, the breakdown for The Flash also comes with a couple of surprising additions. It looks like Man of Steel's Michael Shannon and Antje Traue will return as General Zod and Faora in the Flashpoint-inspired adventure.
Batgirl will also star J.K. Simmons as Jim Gordon, and Jacob Scipio and Brendan Fraser in undisclosed roles (the latter is believed to be playing the villainous Firefly). Loki composer Natalie Holt recently announced that she's signed on to work on the movie's score, while Christina Hodson, who wrote Bumblebee and also worked on Birds of Prey and The Flash, penned the most recent draft of the script.
DC FanDome gave us a first glimpse of some concept art, but now that production is underway, we might just get a look at some set photos in the coming weeks.
