Documentary, public information film, morale booster; propaganda film – all descriptions that apply to Humphrey Jennings and Stewart McAllister's extraordinary war-time film. Using his customary combination of poetry and propaganda, Jennings constructs a collage of the various people and classes of Britain, at home and at work, at war and at peace. The result, while not overtly proselytising, sounded a clear clarion call to internal and international audiences to fight and save Great Britain from the onslaught of war. The film was nominated for the inaugural Academy Award for Documentary Feature in 1943. This government film is a public record, preserved and presented by the BFI National Archive on behalf of The National Archives, home to more than 1,000 years of British history.
