[Possibly fake] video of hunter-gatherer tribe's first contact with people from outside world

[UPDATE: A couple of Boing Boing readers have translated articles that say this encounter was staged. Read the comments below.]

[Video Link] This is a fascinating 15-minute video that shows a hunter-gatherer tribe in Papua New Guinea meeting with people from the outside world for the first time. They are very cautious, but also very curious, about the man on the other side of the river. They eventually cross the river to meet Jean-Pierre Dutilleux, the producer of Tribal Journeys: The Toulambi. When the men see Dutilleux's clothing, they then look at the clothes they are wearing, as if for the first time. When they stroke Dutilleux's hair, they then stroke their own hair.

It looks like all five parts of the documentary are on YouTube.
