From the same creative team that introduced The Lone Ranger, The Green Hornet roared onto radio airwaves in 1936 for a 16 year run.
As we all know, newspaper publisher Britt Reid of the Daily Sentinel adopts the guise of the Green Hornet to infiltrate and expose criminal operations, all the while getting the police and the press to believe that the Hornet was a crook as well. In time, his secretary, Lenore Case, becomes privy to his dual identity, known only to Kato, Reid's Asian associate. I think the idea was for Miss Case to be to Reid what Margo Lane was to The Shadow, but it never got that far.
Al Hodge, better known to fans of Golden Age television as Captain Video, stars as the Hornet/Reid in the 1939 episode, "Put It On Ice":
During the series' run, there were two serials, the first of which featured Gordon Jones, later known from The Abbott & Costello Show, as the Hornet and Keye Luke as Kato. Of course, the most famous incarnation was the short-lived 1966 series with Van Williams & Bruce Lee. During the 70's, Green Hornet was one of a number of radio series picked up by stations around the country on a nostalgic rerun cycle that lasted a few months.
