Warner Bros. folks have been holding secret "funeral screenings" of Batgirl
It's not clear how much footage from Leslie Grace's film is being shown at these screenings for the shuttered movie's cast and crew

It’s pretty much accepted wisdom at this point that those of us in the general public—at least, outside of the single test screening that reportedly helped seal the movie’s doom—are probably never going to see HBO Max’s shuttered Batgirl. For one thing, while the movie was reported as being 90 percent completed, or more, before Warner Bros. Discovery CEO David Zaslav pulled the plug on it a few weeks back, that’s not the same as “in a state where it can plausibly be released.” (Look to Zack Snyder’s Justice League, which required an extremely expensive finishing process and months of work before it could be unleashed to sate a baying public.) And second, any such release would screw up the main reason the company shuttered the movie in the first place: So they could write it off as a loss on their taxes. (Because god help them if this thing actually succeeded!)
