Last October, Warner Bros. announced that Batman: The Killing Joke was being converted into an animated movie. The first R-rated Batman film if you want to keep it a buck. Now The Joker’s most defining story (and arguably the most divisive) story ever told within the Batman DC Universe has a slew of familiar voices coming on for the film, including the greatest voice of The Joker & Batman in DC history as well as an animated film veteran.

Both Mark Hamill & Kevin Conroy are attached to Batman: The Killing Joke in the roles of The Joker & Batman respectively. Tara Strong will step back in the role of Batgirl / Barbara Gordon which should make Batman: The Animated Series fans ecstatic. However, Ray Wise will have to portray Commissioner Gordon as original voice actor Bob Hastings passed away.

Speaking with Comic Book Resources, Hamill discussed his reunion with Kevin Conroy with enough sentiment and joy that you’d think they were brothers or something. “The chance to work 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. “I am beyond thrilled to return as The Joker in The Killing Joke!”

Conroy agreed. “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. Mark always enables me to be a better actor.”

Getting the band back together has proven to be a bit difficult in the past. DC and Warner have trotted out plenty of different Batmans for its animated properties including Jason O’Mara in the Batman v. Robin and Batman: Bad Blood. Hamill has threatened to retire from The Joker position on more than a few occasions but leave it to some great source material to get everybody back on board.

Batman: The Killing Joke arrives on DVD & Blu-Ray later this summer.
