James Cameron is filming a short documentary 3-D movie about the Xikrin-Kayapo tribe which lives in the Amazon jungle. This tribe is fighting a proposed dam on a nearby river which they say will destroy their hunting grounds. The president of Brazil, Luiz Inacio Lula da Silva, has already said that the hydroelectric dam on the Xingu River will be built.

Cameron said that the plight of the Xikrin-Kayapo tribe – which he has already chronicled in one short documentary – reminded him of that of the Na’vi, the blue-skinned aliens whose planet is exploited by a mining company in the blockbuster film. “I want to return to meet some of the leaders of the Xikrin-Kayapo tribe who invited me back,” he said, adding that he had first met the group during a tour of the Amazon to promote Avatar. “I want to take a 3D camera to film how they live, their culture.”

Cameron says his short film about the tribe will be included on the DVD version of Avatar, which is scheduled to be released around Christmas. The new, extended documentary will be slotted around filming of a sequel to Avatar, which is already under way. “The Brazilian Indians, who were desperate, I couldn’t turn away,” he added.
