FYI, it already started airing last December. The fact they got Conroy and Hamil to return to their iconic roles is kinda surprising, especially after I remember Hamil saying he wanted to retire from Joker after Arkham City (his "one exception" being if an animated Killing Joke movie happened, and it did).

I will say if anyone else were to play Joker I'd be cool with Troy Baker, he did a good job in the role in Arkham Origins. (it's interesting to me how the Arkham series had surprising voice roles for both Nolan North and Troy Baker, as North as Penguin is about as far as you can get from his famous "Nathan Drake" voice, and Baker showed he can play a villain just as good as he can play a hero).
