In the 1952–1953 television season, Begley co-starred with Eddie Albert in the CBS sitcom Leave It to Larry. Begley, though only five years older than Albert, played the father-in-law and employer of Albert's character, Larry Tucker, a shoe salesman, who with his young family lives with Begley. In 1954 Begley starred in the NBC Television show, Robert Montgomery Presents, in an episode sponsored by Lucky Strike called Big Boy as Joe Grant, an Engineer for the Union Pacific Railroad living in Cheyenne, Wyoming, who worked on the famous Union Pacific Big Boy steam locomotives. The show is about how Begley's character copes with the transition from steam locomotives to diesel locomotives in the 1950s.
