The Adventures of Robin Hood is a British television series comprising 143 half-hour, black and white episodes broadcast weekly between 1955 and 1959 on ITV. It stars Richard Greene as the outlaw Robin Hood and Alan Wheatley as his nemesis, the Sheriff of Nottingham. The show followed the legendary character Robin Hood and his band of merry men in Sherwood Forest and the surrounding vicinity. While some episodes dramatised the traditional Robin Hood tales, most episodes were original dramas created by the show's writers and producers.
The Adventures of Robin Hood was produced by Hannah Weinstein, who had left-wing political views. Weinstein hired many blacklisted American writers to script episodes of the series: these included Ring Lardner Jr., Waldo Salt, Robert Lees, and Adrian Scott. Howard Koch, who was also blacklisted, served for a while as the series' script editor. The blacklisted writers were credited under pseudonyms, to avoid the attention of studio executives
Each episode in the first two seasons started with a country scene of faux-normal life in Olde England during which an introductory poem in rhymed cadence to the tune of the English folksong "Early One Morning," which derived from a much later period than the series. The poem was a humorous summary vignette of what could be expected in the episode. An actor portraying the Ministrel would use the same melody at the final fade to black before the end credits for 1st run CBS sponsored screenings in the USA, letting viewers know that the sponsor "now begs a word with you."
