Batman: The Killing Joke Official Trailer

We have seen a featurette for the film and several fan edits of the footage from that put together as a trailer, but this here is the first official trailer for the highly anticipated animated adaption of Batman: The Killing Joke.  Based on the controversial classic graphic novel by Alan Moore, this animated adaption sees Kevin Conroy return to voice Batman and Mark Hamill as The Joker.  The animated adaption will be the first "R" rated film of the DC Animated releases. The film is due on Blu-Ray, DVD, and digital later this summer.
