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.

The Wrap confirmed that Perez has been cast as Renee Montoya, a detective working for the Gotham City Police Department who comes into frequent contact with Batman. Montoya is openly gay, has genius-level intelligence, and later assumes the identity of Question.

The Fargo and 10 Cloverfield Lane star is on board as Huntress, a character who has taken on many different forms in the DC Universe. She's been everything from the daughter of Batman and Catwoman to a former mafia princess, who like Batman, witnesses her family killed at a young age. The latter storyline is likely the one we'll see in the upcoming film.

Underground's Jurnee Smollett-Bell beat out Gugu Mbatha-Raw for the role of Black Canary, aka Dinah Lance, who is a street-savvy fighter armed with a shrieking cry.

Robbie will reprise her role as the tough-talking, unhinged Harley Quinn, who favors bats, guns, bubblegum, and her toxic relationship with the Joker.
