From the wiki. Thanks to Ian for the info. I haven't seen this film but it looks good.
Utu is a 1983 New Zealand film directed and co-written by Geoff Murphy; starring Anzac Wallace as Te Wheke, a warrior who sets out to get vengeance after British forces kill his people, Bruno Lawrence and Kelly Johnson. Sometimes described as "a Maori Western", Utu was reputed to have one of the largest budgets for a New Zealand film up until that time.
Partly inspired by events from Te Kooti's War, the film tells of a Māori soldier setting out to get utu, or vengeance, on his former allies after the British army destroys his home village and kills his uncle. The film is set in the 1870s.
In 2013, partly thanks to the longtime existence of an alternative cut of the film aimed at international audiences, which Geoff Murphy had never been happy with, he completed work on a restored and recut version. Utu Redux, as it is known, premiered at the Wellington International Film Festival on 26 July 2013.
