'Avatar' director James Cameron is set to make a 3D film about an indigenous tribe in the Amazon rainforest.

The film is about indigenous people who oppose construction of a huge dam along the border of the Xingu river in the Amazon, which has been approved.

James Cameron will return to Brazil this year to make the film.

"I want to return to meet some of the leaders of the Xikrin-Kayapo tribe who invited me," the Herald Sun quoted him as saying.

"I want to take a 3D camera to film how they live, their culture," he added.

The filmmaker has already visited the Amazon twice in a show of support for the indigenous tribe and to film a short piece on their resistance to the damming project, which will be included on a new Avatar DVD to be released before Christmas.

Speaking of the fight against the dam construction, Cameron said he "did a film on the same topic," referring to Avatar, adding that when he was asked to help "the Brazilian Indians, who were desperate, I could not turn away," he added. (ANI)
