Originally shown on BBC1 in 1974 and rarely seen since, Penda's Fen has become the stuff of legend, its name invoking the spirit of a time when television had the power to provoke and astound. Exploring theme of personal and national identity, language, history and industrial progress, this unclassifiable drama boldly weaves its exquisite, fantastical imagery with the rousing music of Elgar to tell a tale of ancient legends and sexual awakening which stands as one of British television's greatest ever achievements. Released for the first time on DVD, this astonishing work from Alan Clarke (Scum, The Firm and Rita, Sue and Bob Too) has been newly transferred in High Definition, and is presented here with a newly created documentary featuring interviews with its writer David Rudkin and producer David Rose.
