Wolf of Wall Street Actress Margot Robbie has been chosen to play Harley Quinn, the beautiful, yet psychotic girlfriend of the Joker, in the upcoming Suicide Squad movie. Harley Quinn, who first appeared in the animated Batman show in the 1990s prior to her first appearance in the Comics, is a somewhat deranged, yet intelligent psychologist who falls for the maniacal Joker. When not helping Joker bedevil the Batman, Harley (whose real name is Dr. Harleen Frances Quinzel), Harley Quinn is a member of the Suicide Squad, a group of villains drafted by the U.S. Government to conduct special operations of a homicidal nature.While the full cast of the Suicide Squad film is not yet announced, the overall reaction to Margot Robbie's selection has been positive overall. She played a rather crazy role in Leonardo DiCaprio's lover in Wolf of Wall Street, so she could probably pull of being crazy in the Harley role. Margot Robbie is a 24-year old Australian actress who is also appearing in the iconic role of Jane in 2016's new Tarzan film. One question that pops up though, in relation to her role as Harley is her accent. The Harley Quinn most fans know from the Batman: The Animated Show, spoke with a cute Brooklyn accent, and we would assume that is the type of voice expected in any future Harley Quinn actress. Another question of interest is which of Harley's outfits will Margot Robbie wear in the Suicide Squad film? The innocent-looking full-body harlequin onesy we see in the animated show, or the more ribald and sexy look we see in the Injustice: Gods Among Us video game and book series? The costume worn by Harley in the new Suicide Squad comic series is a bit more like a court jester outfit (which is fitting, given the Joker angle), yet is still sexy in a pale breast/cleavage baring sort of way. We shall see how Margot Robbie looks and sounds when the new Suicide Squad movie hits theaters in 2016.
