An independent documentary on the plight of Mexican Indians-specifically, the Otomi people from the Valley of Mezquital, Paul Leduc allows the people to speak for themselves, then analyzes their social, cultural, economic and political condition. This highly original work is an ABC of the cultural assassination of a traditional community, made up of titled sections designed to be shown individually: Antecedents, Bourgeoisie, Classes, Democracy, Ethnocide, Factories, etc. The director of Frida, Leduc casts his "subjects" into an aestheticized space that isolates and heightens the lucid declarations of the Otomi. This film was co-produced by the National Film Board of Canada, and was made possible thanks to research done between 1971 and 1976 by the study project, "Socio-economic Structure and Methods of Domination in the Mezquital Region," under the auspices of the PIVM and the Institute for Social Research of the Autonomous National University of Mexico. A powerful yet controlled exposé of injustice, Mezquital: Notes About an Ethnocide remains one of the most moving of contemporary Mexican films.
