The Green Inferno 2013 is Eli Roth's version of Avatar

In James Cameron's Avatar humans are attacking the forests of Pandora, bulldozing and killing indigenous population of the planet, to get to the natural resources their tribes are sitting at. The military is literally playing a role of guards, for the bulldozers, because the indigenous have become sort of very upset with humans, that terrorize their land. This is sort the plot of Eli Roth's horror film The Green Inferno, just Roth makes it way way more viscerally.
