James Cameron is returning to Brazil to film a 3D movie highlighting the plight of the indigenous people who will be uprooted by the construction of a dam on the Amazon river.
The director has been fighting to ban the Belo Monte hydroelectric plant from being built on the Xingu River, an Amazon tributary, but his protests failed to keep President Luiz Inacio Lula da Silva from approving plans last week.
Now Cameron is planning to show his support for the local tribes by shooting a movie about their lives.
