Outside of the U.S., where the Crown Vic vehicle is prominently produced and used by law enforcement, the producers behind the film decided to give the film different names in foreign countries who would be unaware of the title's meaning. Therefore in Australia, the film is titled "Protect and Serve", in Germany the film is called "In A Web of Violence" and in the UK the film is called "Bulletproof".
Despite its West Hollywood vibe, Crown Vic was in fact filmed in Buffalo, New York.
The film's namesake, the Ford Crown Victoria police interceptor (P71/P7B), was discontinued after the 2011 model year after 20 model years of production. As a sedan, it has been replaced in police service by the Dodge Charger and Ford Taurus, and to a lesser degree the Chevrolet Caprice/Impala. Ford has also made a police version of their Explorer SUV that is very popular for police service.
In the final scene, the quote about violent men and 1984 is wrong. In George Orwell's book 1984, no where in the book is that quote.
