Atherton also starred as cowboy Jim Lloyd in the miniseries Centennial (1978), based on the novel by James Michener. He appeared in the comedy Ghostbusters (1984) as the officious and condescending EPA agent Walter Peck. K. Thor Jensen wrote, "Atherton, who plays cowardly EPA lawyer Walter Peck, is the real villain of the movie (his releasing the ghosts from the containment unit added to the chaos in New York), [he] was so hated that after the movie came out he was harassed on the street and challenged to fights in bars."^[8]
