Actor Margot Robbie says she was left feeling confused by the storyline of her character Harley Quinn in Suicide Squad. The 29-year-old actor is reprising her role in the upcoming Birds of Prey film, directed by Cathy Yan. Talking to Screen Rant, Robbie said she was unable to understand the dynamics between Quinn and iconic DC villain Joker, played by Jared Leto, in the 2016 film. "I guess what's always surprised me, or the thing... and I said this when publicising Suicide Squad, the first film, is that her relationship with Joker always did confuse me the most. That was the thing that took me the longest to get my head around," the actor said. Birds of Prey Trailer: Margot Robbie’s Harley Quinn Teams up with her Fellow Superheroes to Wage a War against Black Mask (Watch Video)

In Birds of Prey, Robbie said, Joker and Quinn are no longer in a relationship. "In this film though we're exploring her not being with Joker. And I actually understand the break-up. That's something I feel like everyone can kind of understand and relate to in some ways. "Though she deals with -- like she blows things up, I don't do that. I understand the motivation that spurred on that train of thought," the actor added. Birds Of Prey New Poster: Margot Robbie As Harley Quinn Imagines Everyone With Wings In This Trippy Poster.
