Continuity mistake: When the lottery winner is going to die, the beer bottle he takes out of the fridge moves all over the place. It even vanishes a couple of times.
Continuity mistake: In the beginning pileup, when the red SUV starts to flip, the front passenger wheel and suspension are ripped off and go off toward the front of the car. Yet, in the next shot, the car has all four wheels. After it shows the Trans Am going in the ditch, it shows the same shot of the wheel coming off from a different angle. (00:11:10)
Continuity mistake: When you see Detective Sueby looking through the glass wall look extremely carefully at Kat's reflection on the glass,she is just about to stand up from her chair.In the very next shot you see that only a second later Kat gets up from her chair a second time. (00:18:50)
Continuity mistake: When Kimberly drives up and block the way, to the high-way, she does a 90 degree turn. Yet when their car gets hit by the truck it's turned back again. Now when did that happen?
Continuity mistake: After Clear and Eugene's deaths Kimberley stares out at the lake and the white van outside the hospital, when Tom grabs her and says,'What are you talking about?', she looks over Tom's shoulder and she sees a newspaper report. You see it has two lines for the headline with a blue sheet of paper above it. In the next close up shot of the report it has one line for the headline and the blue paper is lower down. (01:16:25)
Continuity mistake: When Kimberly is being revived, we are seeing blurry images of the doctor and eventually the heart monitor showing she's flat-lining. What we are seeing is what she is seeing, and since she's flat-lining she wouldn't be able to see anything. She also sees when her heart starts beating again, but when they go back to her, her eyes are closed.
Continuity mistake: At the start when the logs fall off of the truck you see only one chain snap off, before this happens you see that the truck has three chains attached to the trailer.
Continuity mistake: Sometime in the middle of FD1 Alex is walking to Clear's house and Clear says "It's almost Autumn." Alex replies "It's only the middle of June." which means that it must be June. But in FD2 when the main characters are in Kat's car talking about cheating death Kat says "Last May I was..." referring to being on the bus that killed Terry Chaney. It was only one day before Terry got hit by a bus when Alex went to Clear's house. So is it in May (like Kat said) or June (like Alex said)?
Continuity mistake: In the pile-up scene, when Kimberly's car flips over, you can see the rear-left wheel breaking apart, then in a quick shot from a different point of view, it has its four wheels, and the very next shot, the wheel is breaking apart again.
Continuity mistake: When the logs fall off from the truck trailer bed you can see there are no other cars on the highway, apart from the victims', and when it changes to the next shot during the scene there are the same amount of cars on the road as there were before the logs fell off.
Continuity mistake: When Kat is trapped in her car by the log, she pulls out a cigarette and starts smoking. When the worker tries to pry off the door, she says "Could you put it on quiet mode?" and turns away, her cigarette looks completely new. But then five seconds later after her airbag goes off and kills her, her hand drops to the side of the car, but her cigarette is considerably shorter (about half it's length) than it was five second ago. Surely she wasn't able to smoke it all in the amount of time that progressed?
