Other mistake: When Maitland shoots Axel in his house, he has a large calibre hand gun. The shot was in Axel's right arm, just below the shoulder, apparently straight on, as only one hole is seen. The hole was way too small for the size gun and should have easily penetrated into his lungs making it difficult for Axel to breathe. It also would have damaged the bone in his arm making it impossible for him to use it.
Continuity mistake: When the police arrive at Victor's house the guards in the security room decide to run. At this time they are wearing guns in shoulder holsters. When you see them next, running out the door, they are unarmed. You see them again in the van, again with guns and shoulder-holsters.
Continuity mistake: Check out the police car(s) when Axel is in the back of the trailer truck. At first, the police arrive in a then-new 1984 Plymouth Gran Fury, then when the truck flees, the police car reverses back out of the alley, emerging in the next shot as a late 1970's Dodge St.Regis. The next shot has the police car now a 1977 Plymouth Fury, which seconds later changes back again to the St.Regis. (00:04:50)
Revealing mistake: Just before the white Beetle is struck by the truck, it can be seen moving forward as if being driven, but there is nobody in it, and its tires do no touch the ground as if it is on casters being pushed by the green Buick (with black vinyl top) behind it. A tubular brace that might connect the Beetle to the Buick falls off the Beetle's right-side rocker panel when the car is hit. (00:07:15)
Revealing mistake: Near the start of the truck chase, a long shot shows the truck followed by several police cars. In the foreground, another police car's roof comes into view, showing hastily-applied orange numbers on the roof. They appear to be magnetic vinyl, but don't adhere well at all, looking very wavy, with gaps under them. Also, they seem to be applied over faded, yellow, painted, *different* numbers, and are aligned so badly, that the old numbers are very exposed. This error is visible in later shots as well, but most exposed here. (00:05:15)
Continuity mistake: In the last scene (Victor Maitland's house) Taggart, Rosewood and Foley are hiding behind a small wall. After Rosewood says 'I hate machine guns', all three of them shoot back at the gangster, who is trying to gun them down. Foley shoots first, one shot and his gun is empty. One second later he shoots back once more (with the empty gun), and he reloads only after this.
Deliberate mistake: When the truck is slamming numerous parked cars on a residential street, it sideswipes a parked Dodge Aspen (white with tan landau top). At the lower-right corner of this shot, a white Chevy Nova is parked at the corner (its vinyl top and trim has been poorly painted the same white as the body). Both these cars are repositioned to be at the roadblock location at the end of the chase, with the Nova slammed from behind by the truck and the Aspen parked near the cop cars. (00:07:00 - 00:07:40)
Revealing mistake: As Maitland's goons open fire on the main trio, a close-up of Taggart lying across the ground shows pre-cut holes in the grass to simulate where the next barrage of bullets will hit. This error has been fixed on Blu-ray.
Continuity mistake: When Victor catches Axel and Jenny at the warehouse one of Victor's henchmen is holding a gun to Axel's head and his other hand has Axel's sweatshirt in his grasp. Watch the hand holding the sweatshirt, it keeps changing positions as the camera angle changes throughout the scene.
