The first image for the Killing Joke has arrived from The Joke himself, Mark Hamill. Mark Hamill went to twitter to reveal this image:
The quote he put with the image comes directly from the Killing Joke comic book. Mark Hamill of course is reprsising his role has the clown prince himself and Kevin Conroy will be also reprising his role as The Dark Knight.
The image that Mark Hamill tweeted seems to be a screenshot of one of the scenes that happens towards the end of the film and comic book. There has been some rumours that the film will be R Rated because of some odd comments the producer has said.
