For years Pino Solanas has chosen the medium of documentary to show “his” Argentina; it is the natural consequence of a political militancy which has involved him first-hand and of an artistic choice which has from the start seen cinema as a tool for freedom and knowledge. Oro negro is the second instalment of the environmental project started with Oro impuro (2009). The diptych entitled “Tierra Sublevada” completes the ambitious affresco on the Argentina of today, which Solanas started in 2004 with Memoria del saqueo and which is now composed of six distinctive parts, which are nonetheless interconnected. This is once more a collective work, in which the director acts as intermediary between his characters and the spectator, in the conviction that only the awareness of the neo-liberalist attack on the dignity of people and communities allows for an adequate and efficient response.
