Just saw HOME, still planning to see DIRT and now this, CRUDE. (Haven't these people heard of lower case letters?) Another 2009 film about environmental exploitation and the hidden costs of it; mostly poor and/or indigenous people abused by Western companies and consumers.
More at the official website, IMDb, Hollywood and Fine / Crude: The cost of social Darwinism, ifc.com / Joe Berlinger's Crude New Film. From the reviews:
Crude [...] will be in the thick of the Oscar fight.
a heartbreaking and compellingly multifaceted epic about the so-called "Amazon Chernobyl" case
Part of this story was also told in an episode of the tv series Extreme Oil [IMDb].
