We're going to be getting a lot of Harley Quinn over the next few years but another movie can now be added to that list (which currently includes Suicide Squad 2, Harley Quinn vs. The Joker, and Gotham City Sirens). In the video below, the actress confirms that she's also working on a Harley Quinn standalone movie which is described as being "totally separate" from the aforementioned films.
This doesn't come completely out of the blue as it was back in September we learned that Robbie would be executive producing a Harley Quinn movie which most of us assumed would be Harley Quinn vs. The Joker! The whole situation seems pretty confusing, though, as Robbie adds that this movie would need a team of characters for the harlequin of hate to play off. Could it be that this will be a new take on Gotham City Sirens? As of right now, we don't know but it's one of many possibilities.
Either way, it's clear that Robbie has some big plans for this fan-favourite character and that we're going to see an awful lot in the DC Films Universe moving forward. She'll next reprise the role in Gavin O'Connor's Suicide Squad 2 and that movie is currently expected to be released in 2019. We'll see!
