Margot Robbie, director David Ayer reuniting for DC's female led 'Gotham City Sirens'

LOS ANGELES, Dec. 14 (UPI) -- Margot Robbie is set to suit up as Harley Quinn once again in a new female led ensemble film helmed by Suicide Squad director David Ayer.

The project titled Gotham City Sirens, will bring together a collection of female villains from Batman's rogues gallery with the iconic whip-wielding Catwoman and the seductive Poison Ivy joining Robbie's Harley Quinn.

According to The Hollywood Reporter, Robbie has also signed on as executive producer with the script being handled by Geneva Robertson-Dworet who has recently penned the upcoming Tomb Raider reboot and Robert Downey Jr.'s Sherlock Holmes 3. Ayer is also producing.

Gotham City Sirens will mark the second time Ayer and Robbie have collaborated together on a villain-focused team-up film following Suicide Squad which despite being panned by critics, grossed more than $745.6 million worldwide.

Robbie had the standout role in the film as Harley Quinn, the Joker's equally psychotic girlfriend who remains one of DC Comics most popular female characters.

The film was first reported on in May as a Harley Quinn standalone film that would include appearances by the heroic Birds of Prey featuring Batgirl.

In September, Robbie signed a first look deal with Warner Bros. to produce films through her LuckyChap Entertainment banner as she further dabbles in the realm of producing. Gotham City Sirens appears to fall under that deal.

On Monday, Ayer tweeted out a comic book image of Poison Ivy, Catwoman and Harley Quinn with the caption "#Sirens4ever." The image calls back to DC Comics' former comic book series of the same name by writer Paul Dini and artist Guillem March.

The comic series also included appearances from Batman villain and love interest Talia al Ghul, the daughter of the villainous Ra's al Ghul.
