In the Leave it to Beaver pilot, there were many unfamiliar faces among the cast; the character of Ward Cleaver was played by Casey Adams (AKA Max Showalter) instead of Hugh Beaumont and Wally Cleaver was played by Paul Sullivan, not Tony Dow. However, the most fascinating guest star of the show was playing Frankie Bennett, a character who would become known as Eddie Haskell. The boy playing the role was named Harry Shearer.
Harry's parents decided that the life of a child star was not something they wanted for their son, so they pulled him from the show. It would be decades before the world would get to know Mr. Shearer, who has starred in such films as This is Spinal Tap:
and lend his voice to The Simpsons, voicing Ned Flanders and Mr. Burns.
