The official trailer for Batman: The Killing Joke has arrived.
The R-rated animated movie based on the 1988 Alan Moore graphic novel tells the origin story of The Joker and how his obsession with Batman developed. The movie reunites Kevin Conroy and Mark Hamill, who were vocal nemeses in Batman: The Animated Series, The New Batman Adventures and a number of Batman animated movies. Conroy reprises his role as Batman, while Hamill returns as the Joker.
Batman: The Killing Joke will debut at San Diego Comic-Con, which runs July 21–24. It will then be released directly to video.
