The film was originally scheduled to be released on October 5, 2001, but it was postponed due to its terrorism theme and eventually released on Friday, February 8, 2002.
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.
The movie was supposed to include the famous Colombian actress Sofía Vergara, who played an airplane hijacker. But after the September 11, 2001 terrorist attack, the scene where Vergara would hijack a plane was scratched from the movie. Moreover, scenes which might be considered unpatriotic have been excluded.
During the bombing of the consulate, El Lobo is disguised as a motorcycle police officer. His police outfit is identical to that of the T-1000 (Robert Patrick) who was also disguised as an L.A. police officer in Terminator 2: Judgment Day (1991), another film starring Arnold Schwarzenegger.
The film's setting is Colombia, however the film was shot extensively in Mexico, as filming in Colombia would be highly dangerous due to real-life rebel attacks and kidnappings in mountain and jungle regions of that country.
An early draft of this film's screenplay set the action in Libya and involved the Gordon Brewer character tracking down the Arab terrorists who killed his family. Other drafts changed the story's setting (and terrorists) to Colombia.
The credit for composer Graeme Revell appears as we see Brewer and his son playing with a model kit made by the company Revell (presumably no relation).
It was director Andrew Davis's idea to let the movie take place in Colombia.
Cameo: [Sven-Ole Thorsen] Arnold Schwarzenegger's friend and frequent collaborator can be seen sitting outside the café just before the bomb explodes. He is smoking a cigar, which he often enjoys in real life along with Schwarzenegger.
