For the uninitiated, Harley Quinn is a supervillain originally created for Batman: The Animated Series in 1992. She was once a doctor at Arkham Asylum who became infatuated and soon hopelessly devoted to a twisted relationship with Joker, whom she adoringly calls “Mister J” in her high-pitched, thick Brooklyn accent.
Robbie will star alongside Leto, Will Smith (Deadshot), Joel Kinnaman (Rick Flagg), Jai Courtney (Boomerang), Cara Delevingne (Enchantress), Adewale Akinnuoye-Agbaje (Killer Croc) and Viola Davis (Amanda Waller).
The film will follow a group of supervillains, tasked with executing a dangerous and likely fatal mission to have their criminal slates wiped clean.
Suicide Squad is scheduled to hit theaters in August 2016.
