Naqoyqatsi: Life as war is a documentary film released in 2002; it is the third and final film of the Qatsi trilogy by Godfrey Reggio. The film focuses on technology and the perceived lack of natural environments in industrialized society.
Koyaanisqatsi: Life out of balance, the first of the 'Qatsi' films, was released in 1983. The second, Powaqqatsi: Life in transformation, was released in 1988. All three were scored by Philip Glass.
The name of the film is a Hopi word (written properly as naq÷̀yqatsi) meaning "life of war".
In contrast to the first two parts, the majority of Naqoyqatsi was created not by filming in the real world, but by using archive footage and stock images, manipulated and processed digitally on non-linear editing workstations and intercut with specially-produced CGI. Reggio described the process as "virtual cinema."
There was some controversy over the production process after the film was released on DVD. Since most of the archive and stock footage used in the film were shot in a 4:3 aspect ratio, portions of the film were horizontally stretched to accommodate the wider aspect ratio used in the cinema and in the DVD transfer. One of the film's producers later explained in various Internet forums that the stretched image was an aesthetic decision and not a production error.
