“A potent chronicle of the fight between indigenous tribes and government-supported business interests in the Peruvian Amazon.”

- Dennis Harvey

A local Peruvian political-environmental conflict explodes on screen into a far more global concern in the documentary When Two Worlds Collide. The film follows the natives of North Peru as they protest against the regime led by President Alan Garcia, as he pushes pro-mining initiatives to harvest the natural resources of the Bagua Region. Audiences catch a glimpse of what happens when policy pits indigenous people against the state government. When Two Worlds Collide offers a strong perspective into the disconnect between a government and its people, and the consequences faced in the struggle for a healthy environment.
