Harry W. Junkin was a Canadian-born screenwriter who did most of his work from the late '40s through the 1950s in America, and from the 1960s to the '70s in England. While attending school in Winnipeg, Junkin became interested in the entertainment industry. He started out as an actor and also attended the University of Manitoba in the late '30s. After service in the Royal Canadian Air Force during World War II, he went to work in advertising, first in Montreal and later in New York, before he decided to try writing scripts. Initially, his work was limited to writing commercials, through which he also picked up experience as a producer. By the end of the 1940s, however, Junkin had graduated to authoring dramatic scripts and also producing radio shows, among them Radio City Playhouse (for which he was both director and narrator from 1948-1949), Mr. Moto, Mr. District Attorney, Big Town, Mr. Keen, and Tracer of Lost Persons. He made the leap to television in the early '50s, and by the end of the decade had over a thousand radio shows to his credit as a writer, producer, or director, and 700 teleplays, for such series as Studio One, Kraft Television Theatre, Lux Video Theatre, and Philco Television Playhouse, as well as the daytime drama Love of Life and network crime shows such as M Squad. Junkin also authored the screenplay to the MGM drama Slander (1956). He moved to England at the end of the decade, and in the early '60s served as script supervisor on the British television series The Saint and Gideon's Way. He contributed scripts or served as a production executive on such subsequent series as Department S and The Persuaders, and wrote the script for the two-part color Saint episode "Vendetta for the Saint," which were also released as a feature film. Junkin retired in the 1970s.
