I really wasn't expecting this sort of thing so very soon. Filming for Birds of Prey (And The Fantabulous Emancipation of one Harley Quinn) just started two weeks ago, but I guess Warner Bros. saw fit to release a character teaser featuring the gals (Harley Quinn, Cassandra Cain, Black Canary, Huntress, and Renee Montoya) and two of the villains (Black Mask and Zssaz) for the movie:
The movie is continuing off that dirty grungy look that Suicide Squad (2016) had, but it only looks like Huntress (Mary Elizabeth Winstead) is the only one appearing in costume so far (which looks like a mixture of honestly her various costumes).
Really this teaser just showing off the cast as the characters they're portraying. I honestly doubt Jurnee Smollett-Bell as Black Canary will be wearing a lounge dress the entire movie or Chris Messina as Zssaz will be sporting more scars, and Ewan McGregor as Black Mask won't be wearing an actual mask. As for an actual trailer, I probably would bet SDCC we'll probably have an actual one to judge this movie more.
Until then, Birds of Prey (and the Fantabulous Emancipation of One Harley Quinn) will be flying into theaters on February 7th, 2020.
