Once Were Warriors opened the eyes of cinemagoers around the globe to an unexamined aspect of modern New Zealand life. Director Lee Tamahori's hard-hitting depiction of domestic and gang violence amongst an urban Māori whānau was adapted from the best-selling Alan Duff novel. The film provided career-defining roles for Temuera Morrison and Rena Owen as Jake the Muss and Beth Heke. It remains NZ's most watched local release in terms of bums on seats. Among a trio of backgrounders, Riwia Brown writes about adapting Duff's book for the screen.
