It wasn't that long ago rumors began to spread that the highly-anticipated Birds of Prey (And The Fantabulous Emancipation of One Harley Quinn) had begun filming earlier than expected. Now, not only do we have confirmation that production is officially underway, we have a brief teaser to sink our teeths into.

While the video is far from a trailer, it still offers shots of the movie's cast, behind the scenes, yet fully in character. On top of getting first looks at some of the costumes that will be featured in the film, the teaser seems designed to give us a sense of the tone the movie will be going for, and the characterization of some fan-favorite DC Comics characters.

Since the video offers a series of incredibly rapid shots of the movie's cast, here's a full rundown of everyone seen in the teaser of the upcoming DC Extended Universe film.

Harley Quinn

No surprise here. Margot Robbie is back as the breakout character of 2016's Suicide Squad. Much like in the David Ayer-directed film, it appears as if Harley will go through quite a few costume changes in Birds of Prey. Already we've seen that Harley will wear a black, yellow and gold costume (complete with her returning baseball bat), as well as a festive and colorful outfit that is more "night on the town, Harley-style" than "superhero costume."

What's more, the opening shot of the teaser features a close-up shot of Harley's mallet, an instrument the character has yet to wield on the big screen, indicating that we might finally see Harley use her signature weapon in the film.

Black Canary

Jurnee Smollet-Bell's Dinah Lance, aka Black Canary, will form one-third of the titular team. Here, we catch a glimpse of the character, though it's hard to see much of her costume. While we can't say with certainty whether she'll wear her signature fishnet stockings, we do see her sporting a netted dress that could be a nod to the character's comic book look.

During the video, there are two instances where we see the character singing in a microphone, indicating that the DCEU's Black Canary will be inspired by a mix of the recent DC You version of the character, who was an indy rock star, as well as the Bombshells Black Canary, who was an old-timey cabaret-style singer.

Huntress

Played by Mary Elizabeth Winstead, Helena Bertinalli will suit up as the Huntress in Birds of Prey.

From the look of the teaser, it appears as if she will be the most "official" superhero in the film. She's seen wearing something resembling a superhero costume, with a cropped leather jacket and hood, as well as the character's signature crossbow, along with other weapons.

Renee Montoya

Gotham City police detective Renee Montoya may not be the highest profile character in the comic books, but she has a solid fanbase, and a potential future as a superhero, so it makes sense for her to be part of the film's cast.

In the DCEU, she's played by Rosie Perez. It's unclear yet if she will be a friend, foe or frenemy to the BoP in the movie (our money's on option #3) but with her retractable nightstick in hand, it seems clear this Renee Montoya isn't be afraid to get her hands a little dirty.

Cassandra Cain

bop-Ella-Jay-Basco-as-Cassandra-Cain

Ella Jay Basco will play the fan-favorite Cassandra Cain in the film. In the comics, Cassandra is a highly-trained fighter who eventually takes up the mantle of Batgirl, however her much younger age in the film indicates that may not happen for a while -- if at all.

Here, Cassandra appears to be a street-tough kid, with the cast on her arm, which is covered in profanities and insults, indicating that she's both in a bad spot and doesn't have many friends.

Black Mask

We've known for a while now that Ewan McGregor would join the film as Roman Sionis, the villainous cime lord known as Black Mask, and now we finally have our first look at the Batman villain. However, here, McGregor doesn't appear to look like the character in the comics, who wears a terrifying ebony skull mask.

McGregor looks much more like your traditional, eccentric criminal, one that closely follows the aesthetic established in Suicide Squad. However, that doesn't mean that, further down the line, McGregor's villain won't put on a mask to truly bring his character from comics to film.

Zsasz

McGregor's Black Mask isn't the only Bat-villain who will appear in Birds of Prey. Actor Chris Messina will bring to life Victor Zsasz, the terrifying serial killer who covers his body with scars for each and everyone of his many, many victims.

Already, Birds of Prey's version of the character appears to have a few scars on his face, but we won't know the extent of his kill count until he removes that jacket.
