Harry Shearer will be forever more famous for his voice than his face. He provides for many supporting characters of The Simpsons (including Mr. Burns, Smithers and Principal Skinner) as well as the weekly radio program Le Show, which he has done pro bono for over 20 years.
Very, very smart, and equally opinionated, Shearer also happens to be a part-time resident of New Orleans. His latest work includes the documentary The Big Uneasy, a look at the failure of the government to protect its citizens. The week after Hurricane Katrina remains one of the biggest black eyes in American History.
