A new video has surfaced from YouTube where a fan has dubbed in the Joker voice of Mark Hamill for the Emperor in Star Wars.
Hamill voiced The Joker for the Batman: Animated Series back in 1992 as well as Superman: The Animated Series and Justice League.
Long considered a fan-favorite, Mark Hamill voiced the Batman villain for the Arkham video games, and at the 2011 New York Comic-Con obliged a fan's request to say the famous Heath Ledger line from The Dark Knight, "Why so serious?"
Regarding Hamill voicing The Joker again, the actor previously said he was done with the role having retired from doing the character.
It's rumored Mark Hamill will be returning as Luke Skywalker for J.J. Abrams in Star Wars: Episode VII in 2015.
