Yes, I recognize here the true authentic Yves Boisset's trademark, this so brave, bold French director who did not hesitate to make films against power, institution, the French government, against the princes of darkness, the lords of shadows who ruled the country. This one is the first of a long list including R. A. S - Algerian war -, JUGE FAYARD - underworld members "friendship" with politicians -, DUPONT LAJOIE - French genuine racism...This one speaks about the Ben Barka's case, a politician from Morocco who was abducted and supposed killed by the French police helped by French underworld to please the US government, CIA. Trintignant plays a perfect anti hero, a lost in advance soul. You also have here many sub characters with the likes of Michel Piccoli, Michel Bouquet, Bruno Cremer, Philippe Noirt...A dark and gloomy tale but so perfect, so daring, exciting.... Among the best of Yves Boisset. And we also have Roy Scheider is a surprising supporting role, as he will have in UN HOMME EST MORT, made the following year, also with Jean Louis Trintignant.
