Tanna, a tale of tragic lovers, has received Australia's first-ever Oscar nomination for foreign language film.
The film is shot in the indigenous Nauvhal language and uses an entire amateur cast selected from villagers.
Director Bentley Dean moved to island with his wife and two young children and lived there for seven months.
The villagers choose to live like ancestors, without electricity and hunting for food with bows and arrows.
The premiere was held in cyclone-flattened village with a makeshift screen made from sheets tied to banyan tree
