Vale dos Esquecidos (2010)

Instructive documentary about land conflicts in Northeastern Mato Grosso, a state of Brazil. Xavante Indians, squatters, farmers, whatnot. I gave the IMDB year (2010) which is when it was finalized, but apparently it was released in 2011 in Festivals (and a news emission of 2011 was added at the end of the movie), and based on its web page I assume it will premiere in cinemas in April (unless this refers to last year but I think not).
