DCEU: 21 In-Development Movies Ranked From Most To Least Likely

4. Gotham City Sirens

Chances Of It Happening: 2/10

As we already mentioned when discussing Birds Of Prey, Gotham City Sirens sounds very similar to it, at least on a general, conceptual level. We also linked to an article from TheWrap in that Birds Of Prey entry, in which the outlet listed the three Harley Quinn movies that were in contention at Warner Bros.

And Gotham City Sirens was nowhere to be found.

It's becoming increasingly clear that there simply isn't room for two female-centric comic-book movies, both featuring a group of heroines/anti-heroines, and both featuring Harley Quinn.

And though David Ayer is supposedly attached to Gotham City Sirens, the negative reaction to his movies Suicide Squad and Bright - and his commitment to the latter's sequel - may impact his involvement with the project.

So if Gotham City Sirens isn't outright scrapped, expect it to be 'merged' with Birds Of Prey (or vice-versa) in some fashion.

In 2022, he took charge of WhoCulture and has grown it into the biggest Doctor Who channel on YouTube, and one of the biggest Doctor Who communities on the web full-stop. He has been writing and video editing since his early teens, and first got a taste for content creation after making his own Doctor Who trailers, off the back of a burning obsession with the Matt Smith era of the show. Like many his age, he first got into Doctor Who with the 2005 revival, but has since gone back and fallen in love with the classic years too. If you need someone to recite every Doctor Who episode in order, or to give you a random factoid about the making of Gridlock, Danny is the person to ask!
