The only way to catch the Birds Of Prey teaser (officially) is by seeing It: Chapter 2 this weekend

Joker is the one getting extremely long standing ovations lately, but it’s not the only clown-related DC Comics movie that Warner Bros. has in the works. There’s also Birds Of Prey (And The Fantabulous Emancipation Of One Harley Quinn), which is technically a spin-off of the Suicide Squad movie (and maybe a prequel to James Gunn’s Suicide Squad movie?), and WB has just dropped a trailer for it—though there’s an appropriately mad twist for a movie about Margot Robbie’s Harley Quinn. See, Warner Bros. has another clown-related movie that’s in theaters this weekend, and in a fun bit of corporate synergy, the only way to see the Birds Of Prey teaser is by seeing it in front of It: Chapter Two in theaters.
The justification for this is that the Birds Of Prey trailer opens on an It gag, with the WB and DC logos being surrounded by a handful of big, red Pennywise-style balloons. Then, Harley Quinn shows up with a big hammer, smashes the balloons, and notes that she’s “so fucking over clowns.” Get it? Her abusive boyfriend is a clown (sorry, Hot Topic shoppers, but their relationship is fucked up), and the movie this trailer is attached to is about a clown! After that, there are some quick shots of Mary Elizabeth Winstead’s Huntress and Jurnee Smollett-Bell’s Black Canary, plus the tagline “Prey For Gotham,” which is pretty good. Unfortunately, there’s absolutely no way to see the trailer for yourself without sitting down in a theater for the It sequel, which is why we couldn’t see it for ourselves and had to read about it from, oh, let’s say Variety.
