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 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".
