Although Farr was off to a promising start, roles were infrequent for the young actor, and he was cast as a delivery person, a post office clerk, an army store clerk, an airlines reservations agent, and as an employee at a chinchilla ranch--all small roles or bit parts. In 1958, Warner Brothers cast him as the co-pilot of a TB-25 in the Andy Griffith military comedy "No Time for Sergeants", which also brought the young TV comic Don Knotts to motion pictures. Farr appeared as Thaddaeus in the 1965 film "The Greatest Story Ever Told", along with minor roles in "Who's Minding the Mint?" and "With Six You Get Eggroll".
