Deliberate mistake: Hutch is in the trunk of a BMW 7 series ranging in years from 2001-2008. The trunk is equipped with an interior trunk release cable if somebody gets trapped in the trunk. While the car is in motion Hutch manages to free himself of his handcuffs and open the trunk. If the trunk is opened while the vehicle is on a light would flash on the drivers display alerting him/her to "trunk ajar" with a little picture of a car with an open trunk. I know I had one for 5 years. (00:51:50)
Factual error: The film begins and ends with Hutch handcuffed in custody, being interrogated by two police detectives. He was apprehended at the scene of a major violent crime with many fatalities, he has a gunshot wound, and he's a likely murder suspect. In real life, Hutch would be strip searched and treated for injuries under tight security, and he would not be allowed to carry personal effects into the subsequent interrogation. But during the interrogation, Hutch impossibly produces a pack of cigarettes and lighter, a can of cat food, a metal can opener and a live kitten from inside his jacket.
