Mark Hamill is a great Joker, and Ray Wise is an excellent Commissioner Gordon. I’d love to see these two translate to live action some day, but for now all we have are their top notch voice performances in one of the most talked about graphic novels of all time. The Killing Joke has long been a topic of debate amongst hardcore Batman fans, and putting it in movie format has only brought that conversation to a larger audience. This is a really interesting story, and I’d love to hear in the comments what your interpretation of the ending is. The Killing Joke is streaming on HBO and has a runtime of 76 minutes.
