When Mario debuted in 1981's Donkey Kong, he entered a gaming landscape devoid of voice acting, so Nintendo never stopped to think, "Hey, what's this little guy supposed to sound like?" Over the years, though, as Mario entered the world of cartoons, live-action TV shows, and movies, someone had to sit down and decide on the voice of this formerly voiceless character. And decide they did! On this episode of Retronauts, join Bob Mackey and Henry Gilbert as they explore the many voices of Mario, and trace the roots of his current, Nintendo-approved vocal interpretation. Mama mia!
