From 1981–89, Winchell voiced Gargamel on "The Smurfs" as well as on several Smurfs television movies. During the 1980s, he was called upon by Hanna-Barbera to reprise his role of Dick Dastardly on "Yogi's Treasure Hunt" (which was a tour-de-force featuring all of the H-B characters) and later on "Wake, Rattle and Roll" (which was a "Wacky Races" spin-off). Also on the animated movie "Yogi Bear and the Magical Flight of the Spruce Goose", he did the voice of the Dread Baron, who was previously voiced by John Stephenson on the "Laff-a-Lympics".
