Now that Warner Bros. has successfully launched their DC Extended Universe with the blockbuster Batman v Superman: Dawn of Justice, the studio's next installment will focus on a group of nefarious villains known as the Suicide Squad, which hits theaters on August 5. Part of that villainous ensemble is Margot Robbie's Harley Quinn, a character which the studio is doubling down on by developing a spinoff. Margot Robbie is attached to both star in and produce the untitled movie, which won't be a solo endeavor, but focuses on a number of other DC female heroes and villains such as Batgirl and Birds of Prey.

While Batgirl and the Birds of Prey haven't been confirmed for this project yet, The Hollywood Reporter reveals that these characters have surfaced from their sources. There is also a writer attached to develop the project, and while the scribe's identity was not revealed, the site did confirm that the writer is a female. In fact, this report goes on to reveal that it was Margot Robbie herself who initiated the project and brought it to Warner Bros.

After landing the Harley Quinn role in Suicide Squad, the actress reportedly dove deep into the comics to research her character, and during that process, she became interested in the numerous other female characters who are showcased in the DC Comics. She brought on this unidentified writer herself to develop the project, before taking the project to Warner Bros., which was quickly acquired by the studio. It isn't known if there is a director attached at this time, or when the studio may be aiming to release this project.

Harley Quinn was originally created by Paul Dini and Bruce Timm for Batman: The Animated Series, which debuted in September 1992. The character became so popular on the TV series she transitioned into the comics, making her first appearance in The Batman Adventures #12, which debuted in September 1993. In the comics, she's been frequently linked to The Joker, and the upcoming Suicide Squad movie follows suit, with Harley reportedly serving as The Joker's (Jared Leto) romantic interest. It remains to be seen if Jared Leto will reprise his role as The Joker for this untitled spinoff. It's also worth noting that Jena Malone has long been rumored to have played Barbara Gordon/Batgirl in Batman v Superman: Dawn of Justice, although her role was cut from the theatrical version. It is believed that her character will be featured in the upcoming R-rated extended edition of the movie, debuting later this year, but we don't know for sure if she's being eyed for this project.

Harley Quinn has often been compared to Deadpool, since both characters in the comics often break the fourth wall and are known for their foul-mouthed and bizarre behavior. We don't know for sure if Harley breaks the fourth wall in the Suicide Squad movie, or if there are plans for her to do so in the Harley Quinn spinoff, but we'll be sure to keep you posted with more details as soon as we have them. It's also worth noting that Warner Bros.' is also reportedly eyeing Suicide Squad 2 to start shooting in early 2017, with Suicide Squad writer-director David Ayer being eyed to return to the helm.
