La hora de los hornos, or 'The Hour of the Furnaces,' is a groundbreaking 1968 documentary film directed by Fernando Solanas and Octavio Getino that critiques imperialism and explores the political struggles of Latin America. This film is often cited as a foundational text in postcolonial cinema for its powerful commentary on oppression and resistance, using avant-garde techniques to challenge traditional narrative forms and provide a voice to marginalized communities. It connects deeply with the ideas of decolonization and the necessity of revolutionary action against colonial powers.
