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)johnrosa
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)johnrosa
Revealing mistake: When Axel shoots Zack, Maitland's chief thug, Zack stumbles backwards. As he does, he turns his head to watch whether he's stumbling back the correct way (if it had been a result of the bullet impact, his entire body would spin around).
Revealing mistake: Obvious stunt man for Axel when Maitland's thugs toss him out the window. His hair is different and his arms are more muscular.
