Actor Mark Hamill first gained fame for his role as Luke Skywalker in the Star Wars films, but since then he has made a significant name for himself in the realm of animation and video games playing Batman's greatest villain, The Joker.
Having played the role for so long and through a variety of media, it still came as a shock that the word Arkham is rooted so close to home. In fact, it's even in his name, as the above meme points out. It didn't take long for Hamill to react.
At some point, someone needs to find another use for that hashtag because it's fantastic.
Hamill is again reprising his role as the Joker, along with fellow voice actor Kevin Conroy, in DC's animated retelling of The Killing Joke, which releases later this year.
