Behold, the Fantabulous Cast of Margot Robbie's Birds of Prey

The Fargo star has been tapped to play villain Black Mask, EW reports. The character, also known as Roman Sionis in the comics, is the heir to a wealthy fortune who decides to murder his parents and take over their business. He ends up suffering a number of setbacks, personal and professional, that lead him further down a path of villainy and result in his crafting a mask out of pieces of his father's grave (YIKES). Black Mask goes on to lead a gang called the False Face Society of Gotham, but there's no word on whether or not they'll make an appearance in the film.
