Patricio Guzman, a Chilean now living in Paris, began work on this wrenching 2001 documentary after hearing that General Augusto Pinochet had been arrested in London to be tried in Spain for murders he allegedly committed while dictator of Chile. Supporters and opponents of Pinochet march in the streets of London, and in one frightening scene Margaret Thatcher calls him the man “who brought democracy to Chile.” But the film’s emotional core is its testimony from torture survivors and family members of the disappeared, in which ordinary cinematic devices are put to extraordinary use: talking-head shots are imbued with restorative power as the camera rotates slowly around the speaker, defying the torturer’s attempt to obliterate the victim’s identity. Guzman structures his film as a search for irrefutable evidence, whether it’s unearthed human remains or photos of Pinochet’s 1973 coup against Salvador Allende. Guzman also connects close-ups of the victims, speaking proudly of their survival, with an image of Pinochet hiding his face as he emerges from court. In English and subtitled Spanish.
