Margot Robbie on Harley Quinn’s breakup with the Joker in Birds of Prey

The relationship between Harley Quinn (Margot Robbie) and Joker (Jared Leto) isn't exactly the healthiest one on the planet, and the upcoming BIRDS OF PREY (AND THE FANTABULOUS EMANCIPATION OF ONE HARLEY QUINN) will find Quinn having split with the Clown Prince of Crime in order to forge her own path.

"She’s trying to own it," Margot Robbie explained while speaking to Empire recently. "That felt like a real way to deal with a break-up. It’s not clean and easy to be a strong woman. It’s so hard. She’s a bit more Courtney Love than Debbie Harry this time. She says, ‘I’m single, I don’t need him, fuck that guy.’ But if the Joker were to text her, ‘You up?’ she’d run. She’d fall to pieces." Robbie also recently expressed her excitement to Total Film about showcasing a new side of Harley Quinn with BIRDS OF PREY.

Once I started getting to know her, and prepping for [Suicide Squad], I was like, ‘Oh my gosh, there is so much more to be done with this character.' Obviously, you can only do so much in a film like Suicide Squad where there are so many other characters, and you’ve got to be introduced to everyone, and you’ve got a huge plot thing to contend with. So I was just like, ‘There is so much more to do with her.'

BIRDS OF PREY (AND THE FANTABULOUS EMANCIPATION OF ONE HARLEY QUINN) stars Margot Robbie as Harley Quinn, Mary Elizabeth Winstead as Huntress, Jurnee Smollett-Bell as Black Canary, Rosie Perez as Renee Montoya, Ella Jay Basco as Cassandra Cain, and Ewan McGregor as Black Mask. The film will find Harley Quinn, Huntress, and Black Canary teaming up to protect Cassandra Cain when she comes across a diamond belonging to Black Mask, a kingpin in Gotham City's criminal underworld.

The official synopsis for BIRDS OF PREY (AND THE FANTABULOUS EMANCIPATION OF ONE HARLEY QUINN):

You ever hear the one about the cop, the songbird, the psycho and the mafia princess? Birds of Prey (And the Fantabulous Emancipation of One Harley Quinn) is a twisted tale told by Harley herself, as only Harley can tell it. When Gotham’s most nefariously narcissistic villain, Roman Sionis, and his zealous right-hand, Zsasz, put a target on a young girl named Cass, the city is turned upside down looking for her. Harley, Huntress, Black Canary and Renee Montoya’s paths collide, and the unlikely foursome have no choice but to team up to take Roman down.

BIRDS OF PREY (AND THE FANTABULOUS EMANCIPATION OF ONE HARLEY QUINN) is slated for a February 7, 2020 release.
