A special screening to mark 100 years since one of the bloodiest battles of the First World War. Shot and screened in 1916, this UNESCO-listed film was the first feature length documentary about war. Upon release it was watched by around 20 million people, nearly half of Britain's population, hoping to see a loved-one captured on film. A century later this unique footage, now in the care of Imperial War Museums, is being shown to audiences around the world with a specially commissioned orchestral soundtrack composed by Laura Rossi.
