The future of Margot Robbie‘s DC Comics character Harley Quinn is a little unclear at the moment, outside of her upcoming appearance in James Gunn‘s “The Suicide Squad,” a sort of soft reboot-y sequel to the David Ayer film from 2016. While Cathy Yan‘s “Birds of Prey” was originally billed as a solo Harley Quinn film, it ultimately became another group lineup with Quinn partnering up with female characters such as Huntress, Black Canary, Renee Montoya, and the young Cassandra Cain.
