No specific plot details for Birds of Prey have been revealed yet, but reportedly the leading heroines will be clashing with Roman Sionis, a.k.a. Black Mask, one of the most powerful crime bosses in Gotham City. Even if she doesn’t get her superhero on during the movie, Renee Montoya is one of Gotham’s best detectives and knows how to handle herself in a fight, so she’ll be a great ally to the more colorfully-dressed protagonists. With Black Canary, Huntress and Renee Montoya covered, that leaves Cassandra Cain as the final leading lady left to be cast in Birds of Prey. In this movie, however, she will reportedly be a young girl rather than a teenager/young adult as she’s usually depicted.
