[Watch] Mark Hamill’s laugh for The Joker in Batman: The Killing Joke is chilling

Batman fans have been patiently awaiting the release of Batman: The Killing Joke, the animated movie that isn't for children and brings Mark Hamill and Kevin Conroy back to reprise their roles. During his Star Wars Celebration panel, Hamill offered a bit of information on what to expect in the R-rated animated Batman movie releasing this summer, The Killing Joke and tease of what to expect from The Joker in the movie.

We have seen Hamill in action before, thanks to a small clip from the movie, but seeing Hamill do the laugh in person is pretty fantastic.

In addition to his bone-chilling laugh, Hamill gave a bit of insight behind the R-rating, saying that the movie really lives up to its rating. "It's not for kids," said Hamill. "It's earned its R-rating. They really did it like the book. Kids will come up to me and say, ‘Oh, I’m excited for The Killing Joke.’ I said, ‘Don’t you watch that.’”

Batman: The Killing Joke will release on August 2nd, after debuting exclusively at San Diego Comic-Con 2016.
