20 Things You Somehow Missed In Die Hard
15. The Empty Truck
In the opening minutes of the film, the supposed terrorists disembark from a Pacific Courier truck in the underground parking garage of the Nakatomi Plaza. The film shows the truck to be quite empty when they have left it.
However, later in the film, whilst Hans Gruber and his men are planning their daring escape from the building, an ambulance is shown being unloaded down a ramp from the same truck.
As well as being a master planner, Gruber must also be something of a magician, as the van does not leave the parking garage to be able to collect their intended getaway vehicle.
