Looking at IMDb On the Supergirl page, you can see that Sasha Kalle is the only actor currently associated with the film, and the only other person is screenwriter Oren Uziel of 2021 Mortal Kombat fame. Also, the details of this movie are sparse at best, but we know we’ll see an iteration of Supergirl Calle in The Flash. This will serve as a way to introduce the character to viewers and set the stage for her own solo performance. However, it looks like Batgirl’s fate may portend whether or not Supergirl gets a chance to take off.
According to rolling stoneInsiders are pointing out that Supergirl will be next on the cutting board, which isn’t surprising given the recent reshuffle at Warner Bros. discovery. Hollywood Reporter covered the Warner Bros. application. in 2021, which listed the likes of Supergirl and Batgirl that were scheduled to release around 2023, but now we know for sure that’s not the case when it comes to Batgirl. While at the time of this writing, an official statement from Warner Bros. Discovery has not been received, it may appear in the near future. Needless to say, Supergirl is starting to look pretty grim.
