Months ahead of her debut in "Suicide Squad," Warner Bros. is reportedly contemplating a new spinoff film focusing on Margot Robbie's Harley Quinn as well as other female DC heroes and villains. The Hollywood Reporter has learned that Robbie is attached to the project and expected to reprise her role as Harley Quinn as well as produce the film.

Robbie's also reportedly the one who pitched the movie to Warner Bros.; after landing the role in "Suicide Squad," it's said that she researched Harley Quinn's history, "fell for DC's female characters," and brought on a female writer to help develop the ensemble film. She presented it to Warners, who have "snapped it up," according to THR. The writer attached has not been revealed, although she is said to be working on a draft.

The film is also not a Harley Quinn solo film, but rather it will focus on DC Comics' female heroes and villains. While a specific roster has not been revealed, THR notes that Batgirl and the Birds of Prey have been floated -- although it's not clear in what capacity.

It's recently been revealed that a number of other WB/DC film projects are in the works despite not being officially added to the DC Extended Universe's slate, like Ben Affleck's solo "Batman" film and "Booster Gold," which is currently being written.

Robbie will make her debut as Harley Quinn in "Suicide Squad," which opens on August 5.
