The Longest Day (film)
June 2019: the remembrance of the invasion of Normandy in June 1944 – the D-Day landings (“D” stands for Day; as “H” in H-Hour (the moment of attack) stands for Hour).
I have been thinking of the 1962 film The Longest Day (henceforth TLD), certainly a very long film, about the invasion. It was supposed to be a faithful representation of principal events, and boasted, as military consultants, a long list actual participants (the distance between event and film was only 18 years).
