9) The Team Was Created By Harley Quinn’s Creator
As previously mentioned, Gotham City Sirens are far from a major team. Their self-titled comic book series only lasted 26 issues from 2009 to 2011 (when it was cancelled as part of The New 52 studio-wide rebrand). The later run was written by Tony Bedard and Peter Halloway, but the comic was initiated by a name very familiar to fans of Harley Quinn – Paul Dini, her creator.
You might know that Dini was the head writer on the acclaimed Batman: The Animated Series, from which Harley was spawned. The Sirens comic book series naturally explores Harley as a solo character, as she shacks up with Ivy and Selina during a period of separation from the Joker.
If this element is kept for the movie adaptation, it will please those who felt that Harley’s character was lessened in Suicide Squad due to her unwavering devotion to Mr. J. In the Gotham City Sirens movie, she might wake up to the fact that her relationship with the Joker isn’t healthy. At one point in the comics, she even breaks into Arkham Asylum with the aim to kill her Puddin’ (spoilers: she doesn’t go through with it).
