Alfred Hitchcock: ‘A superb fantasist of fear’

Speaking of Hitchcock and fear, I recently learned about the documentary "Night Will Fall" - which is about the British government documentary "German Concentration Camps Factual Survey".

Even the trailer for "Night Will Fall" is shocking - particularly the line, which gives the film its title:

“Unless the world learns the lesson these pictures teach, night will fall.”
