Cinematic luminary Sergei Eisenstein (Battleship Potemkin) conceived this masterpiece montage of Mexico's history that was financed by novelist Upton Sinclair during the Depression. As a result of financial and political pressures, the film was never completed, but the footage was later assembled at Sinclair's behest. Structured in episodic vignettes, the picture offers a dramatic perspective on religion, culture and society.
