‘Towards a Third Cinema’ by Getino and Solanas was a manifesto for a new militant revolutionary Latin American cinema with low budget aesthetics and guerrilla distribution. Shot on 16mm and without sync sound, La Hora de Los Hornos is a monument of that Third Cinema: polemical, partisan and agitational. An immense ‘essay film’, furiously encompassing often pirated documentary footage, intertitles, quotations and voice-over to tell a political history of Argentina, its oligarchs, its violence, its neo colonialism.
