There have been discussions to make a full-length animated feature for Harley Quinn, but there are currently no official plans for one.
With the DC Universe constantly expanding with both live-action and animated content, Deadline asked co-showrunner of the series, Patrick Schumacker, about the possibility of a film centering on Harley and her friends. Schumacker confirmed that the idea of a movie was something he and fellow showrunner Justin Halpern discussed with Warner Bros. Animation while they were waiting for news on their Season 3 renewal. However, with the third season moving forward, plans for the film have been placed on the back burner.
"Right now, we’re not planning on it, but it is absolutely something that we would be interested very much in doing down the road," Schumacker told the publication.
Harley Quinn stars Kaley Cuoco, Lake Bell, Diedrich Bader, Alan Tudyk, Rahul Kohli, Christopher Meloni, Tony Hale, Ron Funches, Wanda Sykes, Natalie Morales, Jim Rash, Giancarlo Esposito, Jason Alexander and J.B. Smoove. Both seasons of the show are available to stream on DC Universe and HBO Max.
