Margot Robbie and 'Suicide Squad' director David Ayer are reuniting for 'Gotham City Sirens'.
Margot Robbie
The 26-year-old actress - who is also an executive producer on the project - will reprise her role as sexy, psychotic supervillain Harley Quinn in the new movie, which will focus on the women from the DC comics, according to The Hollywood Reporter.
In the recent comic series, which the movie will be based on, Catwoman and Poison Ivy featured alongside Harley and could appear in the upcoming film.
'Sherlock Holmes 3' writer Geneva Robertson-Dworet is penning the script.
In September, Robbie was reported to have signed a "first-look" deal with Warner Bros. to produce the Quinn spin-off film.
She is said to have fallen in love with the character after portraying her in 'Suicide Squad'.
It's not known whether Quinn's dangerous lover The Joker (Jared Leto) will star in the spin-off or Batman (Ben Affleck), who is traditionally the superhero trying to stop the pair's criminal plans.
But Robbie has previously admitted she would love Quinn and The Joker to reunite.
She said: "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.
