Hamill began his work as the Clown Prince of Crime in 1992 on the fantastic Batman: The Animated Series, and he continued lending his terrifyingly terrific laugh to the character in shows like Superman: The Animated Series and Justice League.
Mark Hamill is one of the most legendary performers ever to give a take on the role of Batman’s archnemesis.
Some of his most standout voice performances of the Joker, however, came not from animated TV, but rather from the Arkham series of video games.
He recently returned to the role for the Killing Joke movie.
