Well-known Vietnam War veteran and radical anti-war activist Stan Goff briefly worked as a technical military adviser on the film. He later said it was one of the worst experiences of his life and that the finished product was "yet another guns and fire-balls, macho death-cult, fascist film-myth."
After the terrorist attacks on the USA of 11 September 2001, Warner Bros. pulled all advertising of the film which had included a mock newspaper clipping alongside Arnold Schwarzenegger's face featuring the word "bombing" and the tagline "What would you do if you lost everything?" and its Collateral Damage (2002) movie website that had included a game called "Hunting for the Wolf". When the film was finally released in 2002, the film's poster was revamped with shot of an explosion due to the U.S. subsequent invasion of Afghanistan in the background of Arnold's face in the foreground and the film's original tagline missing. The website was completely revamped with nothing but production stills, bios, the film's synopsis, and cast and crew material. The games and other material that had been on the original version of the website were completely eliminated.
When the dinosaur toy explodes, an explosion blows out the windows in the room. The explosion was at the same level of the room, not higher up, where Gordy threw the toy.
