Margot Robbie in an interview with Collider, confirmed that when she pitched the idea of the Harley Quinn spin-off movie from David Ayer’s Suicide Squad, which is now known to be the Birds of Prey movie. The idea was for it to be an R-rated all girl gang movie, because Robbie felt there wasn’t enough movies like that.
She also goes on to say that she also wanted to have a female director be the one to tell the story, which ended up being true as director Cathy Yan (Dead Pigs) was hired on to helm the all female superhero movie.
“I pitched the idea of an R-rated girl gang film including Harley, because I was like, ‘Harley needs friends.’ 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. And then of course having a female director to tell that story.
And giving a female director the chance to do big budget stuff. They always get ‘Here’s the tiny little film’… I was like, ‘I love action. I love action films. I’m a girl. What, are we meant to only like a specific thing’?” So it was a hugely important to find a female director for this, if possible. But at the end of the day — male, female — the best director gets the job and Cathy was the best director.
