For me, the music would completely change the tone of the movie; a scene normally experienced in a calm manner could be transformed by the violin tremelo, indicating suspense or tension, while the operatic female voice dramatized sequences. The sound in this movie seemed sporadic and did not really fit well for me, perhaps because what was being shown on screen and what I heard did not seem cohesive.
Bernard talks about the torture of a young woman, Muriel. According to wikipedia:
"Although the use of torture quickly became well-known and was opposed by the left-wing opposition, the French state repeatedly denied its employment, censoring more than 250 books, newspapers and films (in metropolitan France alone) which dealt with the subject (and 586 in Algeria)."
The torture during the war was "massively employed, but also ordered by the French government, was confirmed by General Aussaresses in 2001."
