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

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

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 the 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.

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.
