Harley Quinn's animated series on HBO Max is back for the first look at season 3 during the DC Fandome live stream. Animation takes forever, as both Harley (Kaley Cuoco) and King Shark (Ron Funches) lament in their introduction to the sneak peek at season 3. It's still unfinished, but even in its sketchy current state, the new season looks awesome as ever – it has what looks like an evil Frank the plant, Harley and Ivy in an actual relationship (finally), and of course, crime shenanigans aplenty.
During an interview in September 2020, Schumacker and series co-creator/executive producer Justin Halpern discussed what lies ahead for Harley and the gang, the move to WarnerMedia's streaming service, and if they would bring an animated Harley to the big screen. With the first two seasons examining Harley breaking away from a literal toxic relationship and establishing her own identity, viewers were left with their pseudo-hero, finally realizing that she wants to explore a real relationship with Poison Ivy. "So, I think in the third season, the general idea we've been talking about… " Halpern noted in the interview, "…When you've mostly been in toxic and bad relationships your whole life, how do you then be in a good one? How does the baggage that you bring from all these other relationships affect the relationship you're in that you really want to work?"
