With Justice League a critical and commercial flop, the future of the DCEU is up in the air at the moment. No doubt there's been some very serious meetings attended by very serious looking men on the Warner Bros. lot as they try and puzzle out how they could have got it so wrong, and one upshot of all this is that the slate of upcoming DCEU films is currently in flux, with various already announced/in production projects probably on hold. One of these seems to be Gotham City Sirens, intended to be helmed by Suicide Squad director David Ayer.
