American actor Harold Goodwin started performing as a child in Los Angeles community theatre. In 1915 he appeared in his first film, The Little Orphan. Though initially cast as under-fed waifs, Goodwin matured into a strapping, athletic leading man, working in roles of varying sizes and importance at Fox, Universal and other studios during the 1920s. He became a close pal and baseball buddy of comedian Buster Keaton while playing the B.M.O.C. villain in Keaton's College (27). Even when Goodwin descended into small character roles in the 1930s, Keaton saw to it that Goodwin was cast in substantial secondary parts in Buster's Educational Studios two-reelers of the 1930s. By 1955, Goodwin had been around Hollywood so long that he was among the film "pioneers" given prominent billing in Abbott and Costello Meet the Keystone Kops. In between acting assignments, Goodwin functioned as a dialogue director. When a British actor named Harold Goodwin rose to prominence in the 1940s and 1950s, the American Harold Goodwin changed the spelling of his first name to Herold to avoid confusion.
