Both Geoff Johns and John Berg, the co-runners of the DC films, are involved in producer roles as well.

It's unknown what other female characters might appear in the Gotham City Sirens movie, but the recent comic book featured Harley Quinn with Catwoman and Poison Ivy.¬†
The release date for Gotham City Sirens is to be announced.
