There's still plenty of secrecy surrounding upcoming DC spinoff flick "Birds of Prey," but a new report claims to shed some light on just who will be joining the titular gang of female heroes and villains.

TheWrap is reporting that it knows which characters from the comics will be appearing alongside Margot Robbie's Harley Quinn in the flick. According to the site, that lineup will include Black Canary, Huntress, Cassandra Cain, and Renee Montoya.

Here's the breakdown of each character, per TheWrap's report:

-Black Canary, aka Dinah Laurel, is a fantastic hand-to-hand combatant who comes from a family of crime fighters. Her father, Larry Lance, was a police officer, while her mother (also named Dinah) was the original Black Canary.

-Helena Bertinelli, aka Huntress, is a vigilante operating out of Gotham City.

-Cassandra Cain is one of the world’s greatest martial artists, and also a vigilante.

-Renee Montoya is a detective working for the Gotham City Police Department. Montoya is openly lesbian, and during The New 52 comics she takes on a costumed identity, becoming the Question.

Making the film as diverse as possible is an important goal of filmmakers, according to Robbie. In an interview earlier this month, the actress said that she wanted the onscreen characters to reflect the fact that "real life isn't ... one specific image."

In addition to the lineup scoop, TheWrap is reporting that "Birds of Prey" will feature a villain from the "Batman" comics "who has never before appeared on the big screen." (So, not the Penguin, then.) We'll keep our fingers crossed that we get some more scoop about the flick during Comic-Con this weekend.
