Winstanley 1975 (A1)

 This is a a good clip from a classic and original look at the ECW - it's up in its entirety and this is the intro which has a good battle scene to get you started; I think it featured the fresh faced English Civil War Society. The blurb reads:

Winstanley is the title of a film made in 1975 in the UK by Kevin Brownlow and Andrew Mollo, based on the 1961 David Caute novel Comrade Jacob. This deals with some of the life story of the 17th Century social reformer and writer Gerrard Winstanley, who, along with a small band of followers known as the Diggers tried to establish a self-sufficient farming community on common land at St. George's Hill near Cobham, Surrey. This was one of the world's first socialistic living experiments which was copied elsewhere in England during the time of the Protectorate of Oliver Cromwell, but was quickly suppressed and in the end left only a legacy of ideas to inspire later generations of socialist theorists. Great efforts were made to produce a film of high historical accuracy. Armour used was actual armour from the 1640s, borrowed from the Tower of London.[1][2] Real-life activist Sid Rawle played a Ranter (English Revolution period anarchist-type group). The film was reissued on DVD and Blu-Ray[3] in 2009 by the British Film Institute (BFI) who funded the original project
