Employed at RKO studios from 1931 through the 1950s, this distinguished and hard-working cinematographer was involved in 91 major film projects and two extended television series. In 1931, he was hired as second cameraman and operator on nine projects. In 1936, Wild shot his first feature, Wallace Fox's sports drama Racing Lady. In 1937, Wild shot the William Christy Cabanne comedy Don't Tell the Wife (1937), about a get-rich scheme gone awry. Portia on Trial and Lloyd Corrigan's romance-comedy Lady Behave followed.
Wild shared an Oscar nomination with Ernest Miller for Republic's Army Girl (1938). The story combines a romantic comedy with a dramatic ending involving military tests between horses and tanks.
