History Trivia / HarleyQuinn2019

* ProductionPosse: The show reunites the showrunners of ''Series/{{Powerless}}'', Justin Halpern, Patrick Schumacker and Dean Lorey, with two of its lead actors, Alan Tudyk (Van) and Ron Funches (Ron).

* TheWikiRule: Has one [[https://harleyquinn.fandom.com/wiki/Harley_Quinn_Wiki here]].

* AuthorsSavingThrow:
** Harley's design. Some people have grown annoyed that Harley traded her jester costume for a more sexualized clown-PerkyGoth look. Here, she wears the jester costume at first, but they explain that she ditches it to distance herself from the Joker after she came to terms with how abusive he was.
** After some complaints of Clayface's relative uselessness, the second season has Clayface be [[TookALevelInBadass far more helpful to the crew]]. It's stated that the plan to save the frozen Harley from Penguin was his idea, and when invading Riddle U, he uses his disguise work to immediately take suspicion off Harley and Ivy. This extends to combat, as he's much more active in fights than he was in Season 1.
** While Bane's characterisation was well-liked by a majority, issues were taken with how he's treated as a NoRespectGuy by his fellow villains. In Season 2, while still treated as a joke, shows that he's a NotSoHarmlessVillain by beating the tar out of Batman even when the latter had his exo-suit.

* CastingGag:
** Jim Gordon's voice actor [[Series/LawAndOrderSpecialVictimsUnit is most famous for playing a cop.]]

** Destined reincarnated lovers Comicbook/{{Hawkman}} and Hawkgirl are voiced by Creator/TylerJamesWilliams and Creator/QuintaBrunson, who play love interests in ''Series/AbbottElementary''.

** Creator/AlanTudyk reprises his role Ocean Master from an episode of ''WesternAnimation/RobotChicken'' of all places.

* RelationshipVoiceActor: Creator/KaleyCuoco (Harley) and Briana Cuoco (Batgirl) are sisters in real life.

* ChannelHop: Seasons 1-2 were made for DC Universe. Starting with [[https://www.polygon.com/2020/9/18/21445329/harley-quinn-season-3-release-hbo-max season 3]], the show is moving to Creator/HBOMax.

* QuoteSource: For {{Cuckold}}.

* ChildrenVoicingChildren: Damian Wayne is voiced by a kid, Jacob Tremblay, rather than an adult woman which is usually the norm for Robins.

* ExecutiveMeddling: Although the team behind the show has said that the people at DC are very supportive and willing to let them do what they want, a scene where Batman preformed oral sex on Catwoman was cut out of season 3. The reasoning is that “heroes don’t do that” (in context, the quote is talking about how making a show about villains frees them up from content restraints) and Batman sells too many toys even though the show isn’t targeted at kids.

* {{Jossed}}: The Joker's throwaway comment in the first episode about having crippled Commissioner Gordon's "partner" led many to think that something along the lines of ''ComicBook/TheKillingJoke'' happened to Batgirl, which was later jossed when she later debuted healthy and fine.

* PlayingWithCharacterType: Creator/MichaelIronside reprises his role as Darkseid from the DCAU, though his depiction here is slightly more sillier than his other roles.

** The episode "A High Bar" has Marcus and Benjamin voiced by Meryl Hathaway and Creator/NicoleSullivan. Joshua averts this due to being voiced by Sean Giambrone.
