The Hour of the Furnaces

The Hour of the Furnaces is a 1968 Argentine political documentary film directed by Octavio Getino and Fernando Solanas. 'The paradigm of revolutionary activist cinema', it addresses the politics of the 'Third worldist' films and Latin-American manifesto of the late 1960s. It is a key part of the 'Third Cinema', a movement that emerged in Latin America around the same time as the film's release. The work is a four-hour trilogy, divided into chapters and united by the theme of dependency and liberation. The first part - "Neo-Colonialism and Violence" - is conceived for diffusion in all types of circuits, and is the one presented at Cannes Classics.
