We know that the new DCU currently being developed by James Gunn and Peter Safran will serve as a relaunch of Warner Bros.' previous DC Comics-based universe, but will it be a full reboot, or will some characters be sticking around?
Conflicting reports have led to a lot of confusion, especially when we know that Gunn will soon begin working on a second season of Peacemaker and a spin-off focusing on Viola Davis' Amanda Waller. In addition, Gal Gadot recently claimed that she was set to return as Wonder Woman for a third movie set in the DCU (although this was later refuted by the trades).
Gunn hasn't addressed Gadot's comments personally, but he did recently suggest that the events of The Suicide Squad would not be canon in the DCU. However, reliable scooper @MyTimeToShine is now claiming that Margot Robbie will return as Harley Quinn at some point.
If this is accurate, it would seem to confirm that Gunn will indeed be picking and choosing which actors remain on board as their respective characters.
Though previous movies featuring Robbie's take on Quinn haven't exactly set the box office on fire, the massive success of Barbie means she's going to be more in-demand than ever, so bringing her back as the unhinged anti-hero would be a smart move.
