Mark Hamill’s greatest post-Star Wars success was voicing the Joker in numerous animated incantations of Batman and he’s had quite a prolific career as a voice actor. However, Hamill actually dabbled in voice acting a bit before Star Wars, starting out with a project which was quite a polar opposite of Batman: an animated version of I Dream of Jeannie. Produced by Hanna-Barbera, Jeannie was a Saturday morning cartoon version of the popular TV show which aired from 1973-75 and you’ll probably recognize Hamill’s voice here as Jeannie’s love interest/master, Corey Anders.
