Versatile comic actor Richard B. Shull attended Iowa State University before making his first Broadway appearance in 1954. Many of Shull's subsequent New York stage appearances have been in plays that looked good on paper but withered in the glare of audience and critical scrutiny (1969's Minnie's Boys, a musical biography of the Marx Brothers, was an all too typical example). He entered films in 1971, enjoying a particularly busy first year before the cameras in Klute, The Anderson Tapes and B.S. I Love You. He was featured on the weekly TV series Diana (1973) and Hail to the Chief (1985), and co-starred with John Schuck in the 1976 sci-fi sitcom Holmes and Yoyo (the producers' plans to make Shull and Schuck a permanent comedy team ended with the series after three months). Richard Shull was for many years the husband of Rhoda star Valerie Harper.
