Longtime Batman producer Michael Uslan seems to be hinting that Batgirl will release on HBO Max this December.
The release window for Batgirl has possibly been revealed by one of the producers of The Batman. Directed by Adil El Arbi and Bilall Fallah , Batgirl is set to star Leslie Grace as Barbra Gordon aka Batgirl who is the daughter of Commissioner Gordon and follows Barbra's adventure as a superhero and pit her against Firefly, played by Brendan Fraiser. The film is set to be released on HBO Max, as opposed to theaters like the other DCEU films.
While set in the DCEU, Batgirl will not feature an appearance by Ben Affleck's Batman but instead Micheal Keaton's Batman from 1989's Batman and 1992's Batman Returns. Keaton will reprise his role as the caped crusader in The Flash, which is slated for release in November 2022 and is set to alter the entire DCEU. Filming is currently underway for Batgirl, which started in November 2021.
A December release date seems plausible, as it would be right after The Flash, and one imagines the involvement of Keaton means they cannot release it until after that film. If the film is set to be released in December, that makes Batgirl the sixth DC movie set to be released in 2022 and the first one exclusively for HBO Max. It also will mark the second DC film for release that December, as Aquaman and the Lost Kingdom is set to open in theaters on December 16, 2022.
This release date window could always change as it is entirely possible Warner Bros. may delay Batgirl to 2023 as to not release too many DC films in one year. Currently, only two DC films are set for 2023: Shazam! Fury of the Gods on June 2 and Blue Beetle on August 16. There are no current release dates for planned DC films like Wonder Twins, Metal Men, Zatanna, or Black Canary.
