Mark Hamill & Kevin Conroy Tease Batman: The Killing Joke Animated Movie

This Summer’s San Diego Comic-Con will see the premiere of the Batman: The Killing Joke animated movie, which will feature veteran voice actor Kevin Conroy back as the Caped Crusader along with Mark Hamill reprising as The Joker.

The duo recently took to Twitter to post an image of themselves.

“I finally caught my favorite villain! Bats nabs Joker,” Conroy posted on Twitter.

Bruce Timm is behind the project and also recently revealed the Batman: The Killing Joke animated movie will feature original footage not a part of the comic.

“The source material is not long enough to make a feature film out of,” Bruce Timm offered. “So we actually had to add a lot more story to it, which is tricky, but I think we came up with a really good solution on how that worked.”

The graphic novel is described by Amazon as:

According to the grinning engine of madness and mayhem known as The Joker, that’s all that separates the sane from the psychotic. Freed once again from the confines of Arkham Asylum, he’s out to prove his deranged point. And he¿s going to use Gotham City’s top cop, Commissioner Jim Gordon, and his brilliant and beautiful daughter Barbara to do it.

Now Batman must race to stop his archnemesis before his reign of terror claims two of the Dark Knight’s closest friends. Can he finally put an end to the cycle of bloodlust and lunacy that links these two iconic foes before it leads to its fatal conclusion? And as the horrifying origin of the Clown Prince of Crime is finally revealed, will the thin line that separates Batman’s nobility and The Joker’s insanity snap once and for all?
