The film features cameos from Marilyn Manson and Charlton Heston. Two celebrities that although not directly involved with the Columbine shooting were certainly made apart of it by the media through blame. Many blamed Manson's style of music and dark demeanor for inspiring the tragedy. Manson felt the acquisition was laughable, stating that he's an easy target because he dresses differently from the common man. Heston on the other hand, was a member of the National Rifles Association. He also delivered gun speeches in Denver shortly after the tragedy, which many saw as insensitive. When Moore interviewed him, he states that he stands by what he did. Although Heston had nothing to do with the shooting, his actions made him become apart of it.
The film received largely positive reviews. It received a 8/10 rating from IMBD, with one user calling it a "very thought provoking film." It received a 96% / 100 from rotten tomatoes, and 3.5/4 rating from Roger Ebert, calling it "hilarious and sorrowful" in its presentation. The film was extremely well received and according to IMBD was a good change of pace from the typical documentary.
