So it can honestly be a bit jarring when someone else takes on the role.
In Batman: Death in the Family, John DiMaggio voices the crazed villain, and he recently revealed that he received feedback on his performance from Hamill himself.
From the moment he first debuted as the voice of the Clown Prince of Crime in Batman: The Animated Series, his sinister and silly presence has delighted fans of all ages.
There have been a number of actors to voice the Joker in the world of animation, though the actor who arguably stands out the most in fans’ minds is the one and only Mark Hamill.
