Factual error: When the shark swims towards the glass, it doesn't move its tail. Sharks have to swing their tail in order to swim. There is no way this shark could be moving.
Factual error: When Christine is about to crush Moochie you see the car is a few inches wider than the entrance to the loading dock. Even a small box truck that you can rent is 7'3" wide so that opening would have to be wider than that for the truck to back in. A 1958 Plymouth Fury is only 6'6" wide. Christine would have had plenty of room to just drive in and crush Moochie. (01:45:45)
Suggested correction: Just to the side there is a sign saying fork lift loading area. A fork lift is much narrower than a truck or a car.
Not disagreeing that a forklift couldn't go down there but @ 1:05:28 you see DANGER spray painted on the right in yellow on the bricks. Below that you see a yellow sign with black letters that say FORKLIFT AREA. Does not say "loading area." Also notice the black rubber bumper that goes across the entire length of the loading dock. That is there to cushion the trailer or box truck when it touches the loading dock. Then the yellow black yellow bumper that goes around the inside of the area is there to protect the building when the driver is backing up with either a trailer or a box truck.
Factual error: When the milk tanker detaches from the truck hauling all of the side lights remain lit. The lights are powered from the truck through cables that would definitely disconnect in this scenario. (00:08:10 - 00:09:00)
Factual error: The car is equipped with shatter-resistant glass yet Cujo manages to break through - even rabid, this should not be possible.
Factual error: One patient had a lobotomy. Impossible as those were abolished in the 1950's by the AMA and patients wouldn't be housed in the same room, too risky as they might attack each other.
