Warner Bros. is still developing Gotham City Sirens, a Suicide Squad spinoff featuring Harley Quinn, Catwoman, and Poison Ivy. The studio officially launched their DC Extended Universe last spring with Zack Snyder's Batman V Superman: Dawn of Justice, which worked to introduce the core superheroes before they return in Justice League later this year. However, it was David Ayer's Suicide Squad that showed fans the darker underbelly of the DCEU with an all-villain team-up - bringing some of DC Comics' most infamous, and beloved, antagonists into the live-action universe. While Suicide Squad as a whole wasn't well received by critics, and inspired a divisive response among casual moviegoers, two highlights of the film were Will Smith's Deadshot and Margot Robbie's Harley Quinn.
Given the response to the first live-action adaptation of the fan-favorite Maid of Mischief, Warner Bros. began planning to build out her character in the DCEU, with rumors circulating of a Harley Quinn spinoff. It was later revealed this film would be Gotham City Sirens, directed by Ayer and written by Geneva Robertson-Dworet. However, when it was recently reported that Warner Bros. is working on a DCEU movie focused on Harley Quinn and Joker (Jared Leto), some rumors pointed to the studio developing this new film instead of Gotham City Sirens - now we know that isn't true.
Forbes, which previously debunked the rumors of a Joker/Harley movie replacing Gotham City Sirens, has further confirmed with Warner Bros. that both films are currently in development. A source told Forbes writer Mark Hughes: "Harley, Catwoman and Poison Ivy are super important to us - And a super cool team, too!" Few details have been revealed about the Gotham City Sirens movie, though Ayer did seemingly confirm it would include Catwoman and Poison Ivy in addition to Harley Quinn. Additionally, it was recently confirmed Leto's Joker will appear, though in what capacity remains to be seen.
As for Joker, the character will seemingly have a large role in the DCEU going forward, with the Clown Prince of Crime also confirmed for Suicide Squad 2 - bringing his total DCEU appearances up to four once (or, if) all these films hit theaters. Plus, Warner Bros. is working on a Joker origin film that will take place outside the DCEU, with a director already locked down.
In terms of when exactly these movies will make their theatrical debuts, we know Suicide Squad 2 is being fast-tracked - and was on the list of confirmed DCEU titles unveiled by Warner Bros. at Comic-Con this summer. Reports on the Harley Quinn/Joker movie indicate it will be released following Suicide Squad 2, and we can assume Gotham City Sirens will be sometime after that. Of course, none of these films have set release dates, though Warner Bros. does have a number of release windows set aside specifically for DCEU entries.
The only films with confirmed release dates are Justice League, Aquaman, Shazam!, Wonder Woman 2, Cyborg, and Green Lantern Corps (though there hasn't been any news regarding Cyborg or Green Lantern Corps in some time). Additionally, neither Gotham City Sirens nor this Harley and Joker movie were on Warner Bros' tentative DCEU release slate from SDCC - which confirmed the titles the studio is prioritizing, including Suicide Squad 2, Batgirl, and Justice League Dark among others. So, while we know a bit about the DC movies Warner Bros. will roll out in the coming years, there is still plenty we don't know about the future of the DCEU.
