There seems to be an ever-growing number of reasons for fans to be excited about The Suicide Squad, with the blockbuster arriving in theaters and on HBO Max this week, and featuring characters from all across the DC universe, ranging from the obscure to the already-iconic. One Squad member who might be in that latter category is Harley Quinn (Margot Robbie), who appears to be at the center of some standout sequences in the film. The Suicide Squad will be the third onscreen appearance of Robbie’s Harley, following 2016’s Suicide Squad and 2020’s Birds of Prey (and the Fantabulous Emancipation of One Harley Quinn). Ever since she was first introduced onscreen five years ago, Harley’s live-action journey has been just as erratic and entertaining as the character herself — and in a roundabout way, it might be the best character arc that the modern DC Films world has had.
