For Troy Baker, Batman: The Long Halloween marked another opportunity to deliver his take on The Joker for a more mature story, having previously in Batman: Arkham Origins and Batman: Assault on Arkham, among other projects. Like in the original Long Halloween story written by Jeph Loeb and illustrated by Tim Sale, Joker was among the many classic villains Batman crossed paths with in his mission to apprehend Holiday, though Joker was also interested in the serial killer, going so far as to try to kill everyone in Gotham Time’s Square on New Year’s Eve in Part One in the hopes that Holiday would be part of the crowd. No spoilers here on how Joker fits into Part Two for those who haven’t read the original story or had a chance to watch the movie yet.
