In 2007, Peru’s then-president called open slather on the country’s natural resources, inviting foreign investors to come a-calling. Trouble was, most of the resources lay beneath constitutionally protected lands, inhabited by indigenous peoples who weren’t consulted. Cue an impassioned plea from indigenous leader Alberto Pizango to cease the pillaging of the land, followed by brewing tensions that exploded into one of the biggest indigenous protests in Peruvian history. When Two Worlds Collide, the Sundance winner for Best First Feature Film, takes viewers into the heaving chaos of the protests, in which injury and death was visited upon both sides presenting a powerful indictment of corporate and political greed and its willingness to trample all in its path.
