Revealing mistake: The blue Willys (Jeep) station wagon used for the blue-screen shots was a two wheel drive version. During the argument shortly before the crash, the Englishman driver abruptly shifts gears, revealing the three-on-the-tree shifter on the steering column, used only on 2WD versions. The on-location filming used the 4WD version, with the logos visible on the tailgate and side of the hood. Also, the distinct 4WD front axle can be seen in many shots.
Revealing mistake: At the end when Culpepper slides down the cable on the palm tree branch, you can see the actual rigging inside the palm tree branch that is used to slide down the cable.
Revealing mistake: Watch the firetruck ladder as it sways. During the long shots showing the entire ladder, it is swaying from ground level. During close-ups, the apparent pivot point is just off the bottom of the screen, indicating a much shorter ladder was in use.
Revealing mistake: At the end when the police officer crashes through the window of the pet store and all the dogs are licking him, it is extremely obvious that it is short piece of footage being rewound and played over and over again to extend the length of the shot.
Revealing mistake: At the beginning of the movie when the car goes through the guardrails and is falling down the mountain side, at first the car is seen coming down sideways, driver side facing down. Then it mysteriously changed to be right side up in the next shot when it crashes.
Revealing mistake: During the whole movie any time someone is driving, the driver turns either way too much or not enough for the turn they are on. Even when they are driving straight, they turn the wheel as if they are going back and forth on the road in both lanes.
