Easton performed on many American television series and made-for-television movies from 1951 to the late 1980s, often portraying in his early roles slow-talking "country bumpkins". His first appearance on television, in a brief uncredited role, was on an episode of The Jack Benny Program, which originally aired on November 4, 1951. Near the end of a comedy Sketch on that episode, Easton, who was cast as a hillbilly, is confronted by another irate mountain man, and the two exchange rifle fire. In 1955, during the first season of the long-running television Western Gunsmoke, he played Chester Goode's younger, prairie-wandering brother in an episode titled "Magnus". He also appeared on several episodes of The George Burns and Gracie Allen Show on CBS in 1957-1958, playing Brian McAfee, a dimwitted student at the University of Southern California. While living in England for several years in the early 1960s, Easton performed too on a variety of British television and radio programs. In 1962 he was cast in the second episode of The Saint, "The Latin Touch", with Roger Moore; and he also provided the voices of "X-2-Zero" and "Phones" in Gerry and Sylvia Anderson's Supermarionation series Stingray. Upon returning to the United States in late 1964, Easton resumed his acting on American television. In "All-Star Munster", a 1965 episode of The Munsters, he was cast yet again as a dimwitted country character named Moose Mallory, a college basketball star. He appeared as well on ABC's World War II drama Combat!, portraying an ill-fated soldier, Woody Jones, in the 1967 episode "A Little Jazz". The following are just a few of the other series in which Easton performed: Screen Directors Playhouse, Dangerous Assignment, My Little Margie, Adventures of Superman, Annie Oakley, The Bob Cummings Show, Riverboat, The Real McCoys, Rescue 8, Father Knows Best, The Red Skelton Show, Wagon Train, Rawhide, The Andy Griffith Show, The Beverly Hillbillies, Petticoat Junction, Get Smart, The Doris Day Show, The Mod Squad, Alias Smith and Jones, and Kolchak: The Night Stalker.
