I watched the Brazilian film "A Idade da Terra" by Glaube Rocha, from 1980 .The film begins five-minute staff of the rising sun, with the Brazilian, indigenous music. The following are alternate shots of contrasts of light and darkness, music, songs and dances, colorful costumes , which remindes me of the famous Carnival in Rio de Janeiro.
Alternate story about the end of the world, with tales of revolutions in the world, the independence of all countries, the totality of U.S. policy. Less knowledge about the historical and social conditions in Brazil ,hinder me in understanding some parts of the film, especially when it comes to associations with some political leaders and political events in Brazil, and the entire film I experienced as a theatrical performance.
I can not say I understand it well enough, just hints of something about which I do not have enough knowledge and information.
