The Battle of the Somme
This astonishing 77 minute film gets a centenary rerelease. It was shot a few days before and after the initial attack on 1 July 1916 by Geoffrey Malins and John McDowell, the only cinematographers allowed anywhere near the front line. It was released in cinemas on 21 August 1916 and an estimated 20 million people saw it — half the UK population. Although conceived as propaganda, it was widely seen as showing the reality of the war.
