"Uncontacted Indians," who have never before had any contact with the outside world, were discovered in the Envira River region in Brazil during a flight in May 2008 according to Funai, the National Indian Foundation, and the group Survival International. The tribe is shown here reacting to the unexpected visit over their camp, located close to the border with Peru.

I've seen photos of tribes much like this one in Sri Lanka but this is an amazing set. It looks like something out of a movie.
