That was filmed in the 90's I believe, though the video at first glance is definitely awesome, there's a few key parts that suggest it's a fake.
The white fellow in the video is a Belgian director by the name of Jean-Pierre Dutilleux.
"Apparently Lemonnier recognized immediately the place where the fake "first encounter" had been filmed. The stream is known as New Year Creek, and the members of the "unknown tribe" probably walked for about a day, from their settlement, to reach the appointed well-lit meeting-place… which had been conveniently cleared for the filming, with a few logs thrown into the creek so that the natives could emerge confidently from the jungle (most unusual behavior) and move naively towards the camera crew. Lemonnier adds: "At that spot, they were about a four-day walk from an administrative center with a school teacher, an airstrip, radio, nurse and Seventh-Day Adventist preachers. Nearby, the navigable river Vailala enables the Papuans to reach the coast, where they exchange bark capes for tools."
"In the video, a native burns his fingers in the flame of a match… as if he were discovering fire! A native picks up a spoon by the wrong end… in spite of the fact that they manufacture wooden spoons! He is astonished by the taste of salt… in spite of the fact that the natives in this region are experts in extracting salt from certain plants. They are astonished by the moviemaker's metal tools… in spite of the fact that all the natives of Papua New Guinea had got around to owning such tools, including those (in a remote corner of the land) who still persisted in manufacturing stone axes.
The article by Sylvestre Huet indicates that the moviemaker Dutilleux did in fact reward the natives for their acting services by giving them medical supplies planned to suffice for six months."
“The most compelling insight of that day was that this awesome recall had been brought about by a fraction of a gram of a white solid, but that in no way whatsoever could it be argued that these memories had been contained within the white solid. Everything I had recognized came from the depths of my memory and my psyche. I understood that our entire universe is contained in the mind and the spirit. We may choose not to find access to it, we may even deny its existence, but it is indeed there inside us, and there are chemicals that can catalyze its availability.”
