Interestingly enough, it’s also expected that The Batman will enter production in early 2020, meaning both of these movies could be filming at or around the same time.
We could be getting a Supergirl movie a little sooner than previously expected.
So perhaps that is paving the way for this Supergirl movie to become a priority?
Another very interesting wrinkle to this whole thing has to do with the Supergirl TV series that is currently airing on The CW.
