Desc: Secrets of the Tribe: Directed by José Padilha. With Robert Borofsky, Jesus Cardozo, Napoleon A. Chagnon, Marie Isabel Eguillor. The field of anthropology goes under the magnifying glass in this fiery investigation of the seminal research on Yanomami Indians. In the 1960s and '70s, a steady stream of anthropologists filed into the Amazon Basin to observe this "virgin" society untouched by modern life. Thirty years later, the events surrounding this infiltration have become a scandalous tale of academic ethics and infighting.
