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 society's transition from a natural environment to a technology-based industrial environment.

Score by Philip Glass.

The name of the film is a Hopi word (written properly as naqö?yqatsi) meaning "life as 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."
