Margot Robbie’s working on a Harley Quinn spinoff that’s not ‘Gotham City Sirens’ or ‘Joker/Harley’

When asked if she was referring to the Joker/Harley movie or Gotham City Sirens, Robbie replied: “No, it’s a totally separate one”.

“There’s a lot going on right now, and I don’t think anyone knows for sure what the next thing to happen, but I think everyone’s keen to get Harley back on screen. Everyone’s working on different versions of what that could be.”
