Bowling For Columbine

Part Two/Two

Bowling for Columbine is a 2002 American documentary film written, directed, produced, and narrated by Michael Moore. It brought Moore international attention as a rising filmmaker and won numerous awards, including the Academy Award for Best Documentary Feature, the Independent Spirit Award for Best Documentary Feature, a special 55th Anniversary Prize at the 2002 Cannes Film Festival and the César Award for Best Foreign Film.

The film explores what Moore suggests are the causes for the Columbine High School massacre and other acts of violence with guns. Moore focuses on the background and environment in which the massacre took place and some common public opinions and assumptions about related issues. The film looks into the nature of violence in the United States.

In Moore's discussions with various people – including South Park co-creator Matt Stone, the National Rifle Association's then-president Charlton Heston, and musician Marilyn Manson – he seeks to explain why the Columbine massacre occurred and why the United States has a high violent crime rate (especially crimes involving guns).
