"The chance to work once again with Kevin Conroy, my favorite Batman, in what some consider the definitive origin of this iconic villain is a dream come true for me," Hamill said in a statement to CBR. "I am beyond thrilled to return as The Joker in 'The Killing Joke!'"

"I've had the great privilege of voicing Batman for more than two decades, and some of my favorite moments in the recording booth have been alongside Mark Hamill," Conroy added. "Mark always enables me to be a better actor. I'm thrilled that we're both back to bring these characters to life in one of the most heralded Batman/Joker stories of all time."

Written by Alan Moore and illustrated by Brian Bolland, "The Killing Joke" is one of the most iconic and acclaimed Joker stories ever published, along with one of the most controversial, primarily stemming from its depiction of brutal violence against Barbara Gordon.
