2016 might be the year of "realizing stuff," but it was also a year of female narratives bubbling to the top of pop culture, from Beyonce and Solange's full-length masterpieces to Hillary Clinton becoming the first female presidential nominee. It's a fitting end, then, that Hollywood is taking steps to become a more inclusive for women at the hands of Margot Robbie, whose first project—the Harley Quinn spinoff movie 'Gotham City Sirens'—was just officially announced.

The film, which was first announced in September, will be written by Geneva Robertson-Dworet of Tomb Raider fame, and will feature a female-led cast of villains like Poison Ivy and Catwoman, as The Hollywood Reporter notes. In other words, you might expect to see Quinn's name again, along with Poison Ivy and Catwoman, on future most-googled Halloween costume lists.

When exactly that will be is still to be determined, as Warner Bros. has yet to set a release date and is juggling a Suicide Squad sequel along with a potential spinoff around Will Smith's Deadshot character. But, considering how enormously successful Suicide Squad was—which grossed over $745 million—chances are they won't be sitting on it for long.
