She's back! Margot Robbie to return as Harley Quinn in David Ayer's all-female villain film Gotham City Sirens

Margot Robbie and 'Suicide Squad' director David Ayer are reuniting for 'Gotham City Sirens'. 

The 26-year-old actress - who is also an executive producer on the project - will reprise her role as the hugely popular supervillain Harley Quinn in the upcoming film.

According to The Hollywood Reporter, Gotham City Sirens will focus on the female villains from the DC universe. 

Acting: Margot Robbie will reprise her role as Harley Quinn in the upcoming all-female DC Comics film Gotham City Sirens 

In the recent comic series, which the movie will be based on, Catwoman and Poison Ivy featured alongside Harley and are likely to appear in the film.

The highly anticipated script is being penned by 'Sherlock Holmes 3' writer Geneva Robertson-Dworet.

In September, Robbie was reported to have signed a 'first-look' deal with Warner Bros. to produce the Quinn spin-off film. 

Who will appear? While Harley is definitely a lock for the film, it's unclear at this point if Enchantress will appear

It's not known whether Suicide Squad's male characters, like Quinn's lover The Joker (played by Jared Leto) or the heroic Batman (Ben Affleck) will appear in the female-fronted spin-off.

But Robbie has previously admitted she would love Quinn and The Joker to reunite, saying: 'I'm trying to make that happen. Not for anything specifically, but just something - there's so much more to do.' 

Meanwhile, Warner Bros is also working on a 'Suicide Squad' sequel and a spin-off for Will Smith's character Deadshot.

'I'm trying to make that happen!' Margot has admitted that she wants Harley Quinn and Jared Leto's The Joker to reunite in another film 

Another spin-off: Will Smith is also getting his own Suicide Squad spin-off for his character Deadshot 

Despite being slammed by critics, Suicide Squad was a sizeable box office upon its release this year, grossing over $745 million.

An official sequel is currently scheduled to start filming next year.

Other DC movies on the way include Wonder Woman and Justice League. 

Not another one! A Suicide Squad sequel is set to film next year
