When Allied forces liberated the Nazi concentration camps in 1944-45, their terrible discoveries were recorded by army and newsreel cameramen, revealing for the first time the full horror of what had happened. Making use of British, Soviet and American footage, the Ministry of Information’s Sidney Bernstein (later founder of Granada Television) aimed to create a documentary that would provide lasting, undeniable evidence of the Nazis’ unspeakable crimes. He commissioned a wealth of British talent, including editor Stewart McAllister, writer and future cabinet minister Richard Crossman – and, as treatment advisor, his friend Alfred Hitchcock. Yet, despite initial support from the British and US Governments, the film was shelved, and only now, 70 years on, has it been restored and completed by Imperial War Museums under its original title "German Concentration Camps Factual Survey".
Night Will Fall is a 2014 documentary film directed by Andre Singer that chronicles the production of the 1945 British government documentary German Concentration Camps Factual Survey, which showed gruesome scenes from newly liberated Nazi concentration camps. The 1945 documentary, which was based on the work of combat cameramen serving with the armed forces and newsreel footage, was produced by Sidney Bernstein, then a British government official, with participation by Alfred Hitchcock. It languished in British archives for nearly seven decades before being completed in 2014. About 12 minutes of footage in the 75-minute Night Will Fall is from the earlier documentary.
