Such a shame Keaton has to be involved in this mess. Suppose there's nothing WB can do now.
Yeah, its certainly a cluster.
As far as Keaton goes, one option
at this point for Keaton's Batman, is to just release
Batgirl as is with him as Batman and move forward from there in terms of his version of Batman.
The issue with that ,of course, is that there won't be an explanation for Keaton suddenly being Batman again.
However , audiences have shown they're willing to just go with the idea that Pattinson is Batman in one film, Phoenix is Joker in another film etc. if the film knocks it out of the park.
It's not a perfect solution by any means, and it has its set backs.
But facing reality, there really aren't going to be any perfect solutions .
Just alot of bad to worse solutions.
Given that this will be the first Batgirl film, they'll probably have leeway to set their own rules, in the eyes of the GA.
If Keaton happens to be the Batman of this film, then it's easier for audiences to just go with it.
If WB made Batgirl a more of a self contained film like Aquaman, WW( i.e. it's not totally reliant on other characters and events in the DCU), it could work.
Now that's assuming Batgirl is much more focused on the characters in Gotham , and not trying to bend over backwards to connect to the wider DCU.
They've got a year , so a better option may come along.
But looking at things now, I think that's one way to proceed.
