The sound from the TV as Johansson is celebrating Christmas with his son and his ex-wife has the items of the Disney Christmas Special, shown every Christmas in Sweden, coming in the wrong order. When they are sitting in the sofa, the sound is from Clown of the Jungle (1947), whereas when Johansson is leaving, the sound comes from the end of Santa's Workshop (1932), which is always shown first.
The security guard who comes forward with a belated piece of information claims to have been on vacation to Gambia over the holidays, presumably to escape the Swedish winter, but he shows no signs of any tan.
The film shows it to be completely dark outside when Johansson is celebrating Christmas with his son and his ex-wife; however, when he leaves, they are still watching the Disney Christmas Special which airs every Christmas in Sweden at 15.00 CET. There is still daylight in the Stockholm area by then.
During the car chase, one close-up shows Johansson's hair flowing in the wind, revealing that it has been shot through an open window on the car's passenger side. People do not otherwise tend to drive with their windows open in Swedish sub-zero temperature winters - especially not when speeding.
When the Minister of Justice is watching TV in his home, his head ever so slightly jumps to the side when switching channels, revealing that the shot consists of two takes being spliced together.
Johansson describes what the Minister of Justice is watching on TV as "people sitting in shelves on top of each other" (possibly Prat i kvadrat (1983)), but when the TV is shown it looks nothing like that.
When the inspectors respond to the alert about the robbery, they fail to identify themselves by unit number, which is compulsory. (Later in the film, we learn that their unit number is 1648.)
