Harley Quinn movie in the works, confirms Margot Robbie

Actor Margot Robbie, who essayed the role of Harley Quinn in "Sucide Squad", has confirmed that a "totally separate", film focusing on the character, is in the works.
Following the character's debut in "Suicide Squad", Robbie and director David Ayer were confirmed to be developing spin-off film "Gotham City Sirens", while "Crazy Stupid Love" directors Glenn Ficarra and John Requa were in talks to write and helm a movie about 'Harley and Joker'.
"I've been working on it for two years now. I mean, it's hard to kinda talk about it 'cause all this stuff is kinda under lock and key, but yeah, no, I've been working on a separate spin-off for Harley, thing, for a while now," Robbie told MTV News in an interview.

"There's a lot going on right now and I'm not sure I, honestly, I don't think anyone knows what's going to be the next thing to happen, but I think everyone's keen to get Harley back on screen and so everyone's working on different versions of what that could be," she added.
