John DiMaggio has the kind of résumé that would leave most voice actors envious. He’s best known for his work on Futurama as Bender, but he’s also made appearances on Adventure Time, American Dad! and Samurai Jack. At this year’s San Diego Comic-Con, he took part in the I Know That Voice panel. The 2013 documentary is being developed into a television series, with each installment focusing on a particular voice actor and exploring their creative process and career trajectory. Before the panel, we sat down with DiMaggio to find out which classic voice actors most inspired him.
