The effects of Deadpool’s success on the superhero movie industry are already being felt, it seems. The animated adaptation of Batman: The Killing Joke, one of the most acclaimed and controversial comics of all time, has been rated R. The original comic, which was written by Alan Moore and drawn by Brian Bolland, is exceptionally controversial. The book is exceedingly violent, graphic, and vividly depicts the sexual assault and paralysis of Barbara Gordon, the original Batgirl. Usually this would be enough to sink its reputation beyond repair. But The Killing Joke is also probably the single most definitive comic about the Joker and Batman’s relationship of all time.
Fans have been clamoring for a film adaptation of some sort for years. They aren’t the only ones. At one point, Mark Hamill (the iconic voice of the Joker in Batman: The Animated Series and the Arkham Asylum video games) said that he’d come out of Joker retirement were he presented with the opportunity to voice the character in a Killing Joke adaptation.
