Mungau Dain was a ni-Vanuatu actor and villager who starred in the 2015 Australian-Vanuatuan film, Tanna. Dain, who had never acted before, was cast in the film alongside Marie Wawa, another Yakel villager, and other local untrained actors. Tanna, which is based on the true story of a ni-Vanuatu couple in 1987 who committed suicide after their tribes refused to allow them to marry, won the Audience Award Pietro Barzisa at the 72nd Venice International Film Festival in 2015 and was nominated for a Best Foreign Language Film at the 89th Academy Awards in 2017. Dain, who reportedly had never seen a movie before his casting, traveled internationally in support of the film, including to Australia, Los Angeles and Venice.
