Dan Castellaneta is most famous for his role as Homer Simpson on the long-running animated television show The Simpsons. The Tracey Ullman Show included a series of animated shorts about a dysfunctional family. Voices were needed for the shorts, so the producers decided to ask Castellaneta and fellow cast member Julie Kavner to voice Homer and Marge Simpson rather than hire more actors. Homer's voice began as a loose impression of Walter Matthau, but Castellaneta could not "get enough power behind that voice" and could not sustain his Matthau impression for the nine- to ten-hour long recording sessions. He tried to find something easier, so he "dropped the voice down", and developed it into a more versatile and humorous voice during the second and third season of the half-hour show. Castellaneta's normal speaking voice has no similarity to Homer's. To perform Homer's voice, Castellaneta lowers his chin to his chest, and is said to "let his IQ go." Castellaneta likes to stay in character during recording sessions, and tries to visualize a scene in his mind so that he can give the proper voice to it. Despite Homer's fame, Castellaneta claims he is rarely recognized in public, "except, maybe, by a die-hard fan."[1]
