Harley Quinn is returning for Gotham City Sirens, probably teaming with Catwoman and Poison Ivy
David Ayer, director of Suicide Squad and the forthcoming Sirens, tweets image of Harley Quinn with Catwoman and Poison Ivy – but what of Batman and The Joker?

Suicide Squad star Margot Robbie is returning to the live-action DC cinematic universe, and she’s bringing a familiar foe with her.
According to the Hollywood Reporter, Robbie will reprise her role as Harley Quinn in Gotham City Sirens, which will be directed by Suicide Squad’s David Ayer. Robbie will also serve as an executive producer.
Ayer will once again be directing a DC Comics movie with a cast full of bad guys, as Gotham City Sirens, like the comic book of the same name, will feature some of DC Comics’s most popular female villains.
Ayer tweeted out an illustration of Batman villains Poison Ivy, Catwoman and Harley Quinn with the hashtag #Sirens4ever, an obvious hint as to which characters will be in the film.
If Catwoman does appear, she’d be taking part in DC Comics’s newly connected movie universe for the first time. We last saw the character in Christopher Nolan’s The Dark Knight Rises, where she was played by Anne Hathaway.
