Mark Hamill played Joker in live-action 22 years ago, but the DC production is rarely remembered. Mark Hamill is responsible for one of the most beloved depictions of Joker that debuted in Batman: The Animated Series, though he has reprised the role for several other animated productions such as Justice League and Batman: Mask of the Phantasm. Due to how prolific he has been with the character across animation, Hamill is often considered the archetypal voice for the Joker, while Heath Ledger is often considered the quintessential Joker in live-action.
