While speaking with Rotten Tomatoes during a press junket for the film Child’s Play, the very talented Mark Hamill shared some of his most beloved voice acting roles, especially that of The Joker in Batman: The Animated Series. Hamill shared that he was nervous about the part and became really intimidated when someone mentioned to him that he would be “following Jack Nicholson“, who iconically played The Joker in the 1989 film Batman.
