The Joker-centric tale features the voice of Mark Hamill as the villain, as he has many times before to tremendous effect. The story provides an account of all of the many hardships that befell an ordinary man and turned him into Batman's top foe. Also figuring heavily into the story is Barbara Gordon aka Batgirl, who has an encounter with Joker that many still deem highly controversial.
Also included is a featurette that digs deeper into how the comic was adapted, and it's suggested there are some changes to some key characters, including Batgirl. Batman: The Killing Joke hits DVD this summer.
