Since he began his career in the late 1950s, Pollard has been a frequent guest on TV on everything from "The Andy Griffith Show" to "Alfred Hitchcock Presents" to "Star Trek". He was a regular in support of Harvey Korman and Valerie Perrine in the short-lived sitcom "Leo and Liz in Beverly Hills" (CBS, 1986). Pollard was formerly married to actress Beth Howland, remembered as Vera in the long-running sitcom "Alice".
