From Wikipedia, the free encyclopedia. Harry Julius Shearer (born December 23, 1943) is an American actor, comedian, writer, voice artist, musician, author, radio host and director. He is known for his long-running role on The Simpsons, his work on Saturday Night Live, the comedy band Spinal Tap and his radio program Le Show. Born in Los Angeles, California, Shearer began his career as a child actor, appearing in The Jack Benny Program, as well as the 1953 films Abbott and Costello Go to Mars and The Robe. In 1957, Shearer played the precursor to the Eddie Haskell character in the pilot episode for the television series Leave It to Beaver, but his parents decided not to let him continue in the role so that he could have a normal childhood. From 1969 to 1976, Shearer was a member of The Credibility Gap, a radio comedy group. Following the break up of the group, Shearer co-wrote the film Real Life with Albert Brooks and started writing for Martin Mulls television series Fernwood 2 Night. In August 1979, Shearer was hired as a writer and cast member on Saturday Night Live. Shearer describes his experience on the show as a living hell and he did not get along well with the other writers and cast members. He left the show in 1980. Shearer co-created, co-wrote and co-starred in the 1984 film This Is Spinal Tap, a satirical rockumentary about a band called Spinal Tap. Shearer portrayed Derek Smalls, the bassist, and Michael McKean and Christopher Guest played the other two members.
