OK, his voice. His second voice, to be exact. Henry Corden was the voice of Fred Flintstone from 1977 to a recent commercial. He died last night at age 85. Corden replaced original Fred Flintstone Alan Reed when Reed died in '77. Reed is the voice from the original Flintstones series, and Corden was Flintstone in the later Flintstones series and movies and video games from 1977-2000, as well as all those Fruity Pebbles/Cocoa Pebbles commercials.
