DCEU star and Harley Quinn actress, Margot Robbie, has expressed her interest in getting Poison Ivy to play a part in a live action DC film. Harley and Ivy have a complex history with each other and their relationship has developed substantially in the adult animated series Harley Quinn on HBO Max. They started off as friends, but their platonic bond steadily blossomed into a passionate romance. This dynamic between Harley and Ivy in Harley Quinn has been extremely popular amongst both superhero fans and Margot Robbie herself, making the chances of a DCEU Poison Ivy appearance very likely.
