Harmon has also made several television and theatrical films throughout his career. In the late 1970s, he had supporting roles in Comes A Horseman and Beyond the Poseidon Adventure. His most prominent starring roles were in the 1986 romantic comedy Prince of Bel Air and 1987 comedy Summer School in both of which he co-starred oposite Kirstie Alley, and the 1988 thriller The Presidio in which he co-starred with Sean Connery and Meg Ryan.
