“I pitched the idea of an R-rated girl gang film including Harley, because I was like, ‘Harley needs friends,’” Robbie told Collider. “Harley loves interacting with people, so don’t ever make her do a standalone film. She’s got to be with other people, it should be a girl gang. I wasn’t seeing enough girl gangs on screen, especially in the action space. So that was always a big part of it.”
