The last we heard about Gotham City Sirens, David Ayer was still on board to direct Warner Bros.' Suicide Squad spinoff, with Margot Robbie reprising her role as Harley Quinn, and Jared Leto potentially returning as the Joker. However, a new wrinkle in the studio's rapidly developing plans for the Clown Prince of Crime could see Gotham City Sirens usurped by the Joker and Harley Quinn movie.
The Tracking Board contends this "criminal love story," written by Glenn Ficarra and John Requa (Crazy, Stupid, Love), "would take the place of Gotham City Sirens, which has been reconceived." The website adds that would mean Ayer, who wrote and directed Suicide Squad, is no longer attached to any DC Extended Universe films.
Inspired by the DC Comics series of the same name, Gotham City Sirens would've teamed Robbie's Harley Quinn with fan-favorite villains/antiheroes Catwoman and Poison Ivy. As recently as last month, Ayer seemed to push back against a report that his involvement with the spinoff was in doubt.
The Joker and Harley Quinn development, and the Gotham City Sirens rumor, arrive on the heels of a report that Martin Scorsese is producing a Joker origin movie that would fall under a new line of DC movies unconnected to DC Extended Universe continuity.
Although the Suicide Squad sequel has yet to lock down a director, the film is reportedly being fast-tracked by Warner Bros.
