Mark Hamill performs dialogue from ‘Batman: The Killing Joke’ live at Star Wars Celebration

Star Wars Celebration 2016 is currently underway in London, and Star Wars star Mark Hamill is there to promote the upcoming movies.

During a Q&A segment, a fan told him that he was looking forward to Batman: The Killing Joke, which prompted Hamill to talk about it and even read some dialogue in his Joker voice!

Hamill said “be careful what you wish for” and stressed that the movie is not for kids and “earns” its R rating. Then, all on his own, Hamill took out his iPhone and read some lines from Batman: The Killing Joke in his iconic Joker voice. We even got a laugh at the end. Check out the video above!

Batman: The Killing Joke is available for pre-order on Amazon now. The movie hits Digital HD on July 26th, and Blu-ray/DVD on August 2nd. It will premiere at San Diego Comic-Con on July 23rd.
