Larry Simms sometimes also appeared in movies out of the Blondie Series, most notably in two films of Frank Capra: He played one of the sons of Governor Hopper (Guy Kibbee) in Mr. Smith Goes to Washington (1939) and Pete Bailey, the oldest son of James Stewart's George Bailey in It's a Wonderful Life (1946). Not very interested in acting, he quit show Business to join the Navy (he appeared in uniform as himself in the Columbia Screen Snaphots short, Hollywood Grows Up), then studied aeronautical engineering at California Polytech. Simms later worked at Jet Propulsion Laboratory (JPL) in Pasadena, California and around the world as an Engineer until his retirement. In his last years, Larry Simms lived in Thailand with his wife.
