Since then, Robbie has reprised the role in 2020's Birds of Prey, which featured an all-female cast and was directed by Cathy Yan. Robbie is set to play the character again in the upcoming The Suicide Squad film, which will be directed by James Gunn.
While it would make perfect sense for the DCEU to bring back Margot Robbie to play Harley Quinn in future films, it looks like her appearance in The Suicide Squad on July 28, 2021, might be her last.
Is Harley Quinn going to die in The Suicide Squad?
During an interview with Entertainment Weekly, Robbie revealed that she didn't know that Harley had died in Batman's arms as shown in the film's epilogue, which is also known as the Knightmare scene. She also went on to thank the interviewer, while expressing that she has no qualms about Harley's fate in Zack Snyder's DCEU films.
Having said that, we'd like to confirm that Harley Quinn isn't going to die in The Suicide Squad. At least, not to our knowledge.
However, it looks like it is Robbie who has had enough playing the psychiatrist-turned-villain for two straight films. In the same interview with Entertainment Weekly, Robbie revealed that she had to film Birds of Prey and The Suicide Squad back to back. She says that she needs "a break from Harley because she's exhausting" and that she's just as "intrigued as everyone else is" as far as her future in the DCEU goes.
This is a surprising sentiment when you consider both Harley Quinn's popularity and that of Margot Robbie.
Harley Quinn's popularity has surged over the past decade. In addition to Robbie's successful portrayal, Harley Quinn has also appeared in other media such as in the Injustice video games with a cameo as a playable skin in Mortal Kombat 11. She's also had an animated show with the adult-oriented Harley Quinn animated series.
On top of these confirmed appearances and projects, Harley Quinn was set to appear in other works as well. This includes a romance film that was supposed to revolve around the love story of Harley and Joker, as well as a standalone Harley Film. There were reportedly plans for Harley to team up with Catwoman and Poison Ivy in Gotham City Sirens as well. There are also talks that a Birds of Prey sequel might happen a couple of years down the line.
None of these said projects have been confirmed outside of preliminary talks. If The Suicide Squad is indeed the last time we'll get to see Margot Robbie as Harley Quinn for a while, then we're thankful for Robbie's dedication to the role.
What's next for The Suicide Squad?
Written and directed by James Gunn, The Suicide Squad is scheduled to premiere in theaters in the United Kingdom on July 30, 2021. A week later, The Suicide Squad will be shown in theaters in the United States on August 5, before being available on HBO Max.
With only a few weeks to go before its premiere, we can expect more interviews from cast members, TV spots, as well as trailers, to drop, as the hype surrounding the film reaches a fever pitch.
