Clyde also kept busy as a character actor in feature films; for example, he played a sad provincial postman in the Katharine Hepburn film "The Little Minister" and Charles Coburn's drinking buddy in "The Green Years". In the 1940s, he gravitated toward outdoor and western adventures. Clyde is well remembered for his roles as a comic sidekick, usually teaming with William Boyd in the "Hopalong Cassidy" series, as "California Carlson" (a role he also played in the "Hopalong Cassidy" radio program), or with Whip Wilson in Monogram Pictures' low-budget western movies. Clyde also worked on the Hopalong Cassidy "record readers" issued by Capitol Records in the 1950s.
