Il y a soixante-cinq ans, le monde découvrait les films réalisés par les Alliés dans les camps de concentration et dans les camps d’extermination. Bien que nous ayons eu leurs images, nous en connaissons peu, si du tout, leurs auteurs et encore moins, les conditions de leur réalisation. We have decided to follow the path of three of these producers' images, these film directors who came from Hollywood: John Ford, Samuel Fuller, and George Stevens.
In 1945, the pictures of Dachau taken by Stevens' crew are inserted into a documentary, first shown in the United States, before being projected and used as evidence of the Nazis' crimes before the International Military Tribunal at Nuremberg. It is John Ford, who has undertaken this unprecedented experience. He directed himself a special unit, the Field Photographic branch (FPB), responsible for the production of films such as The Nazis concentration camps, and for the organization of the filming of the trial.
