Toulambi - another footage of first contact

That movie was fantastic. The amount of isolation of the Guinea people from the rest of the world was unbelieveable (as I understood, they didn't even know that ocean existed). The most fantastic thing, however, was the amount of genuine footage that the Leahy brothers were able to film.

I have encountered another footage that presumably shows a primitive tribe making their very first contact with white people. But I'm not sure this footage is genuine, many people insist that it has to be fake, yet others say that it is all real (not staged for the camera).
