Revealing mistake: When they are all in the van to meet the pregnant woman, tyre marks from the camera car are visible.
Visible crew/equipment: During the highway pile-up Rory's car barrel rolls in slow motion over an unmanned camera, during this shot you can see the cannon on the bottom of the car used to flip it. Then in the very next shot you see the car barrel roll from a different angle and the unmanned camera from the first shot is visible. It doesn't look like a typical camera, its disguised as debris, but it would not be there had the slow-mo shot not been filmed.
Revealing mistake: In the pile-up scene when Kim's car starts to flip, you can see that the driver side window is removed and placed with plastic wrap, probably to protect the driver. This is on the DVD.
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)?
Visible crew/equipment: When we see Clear looking at Kim leaving on the screen, the camera can also be seen on the screen. (00:35:25)
Suggested correction: There is no camera on the screen.
Revealing mistake: When Evan slips and falls on his back, you can see the 'ground' vibrates right when Evan's body hits it. With that amount of impact, a concrete ground wouldn't visibly vibrate like that. Of course the filmmaker wouldn't let the actor fall on something concrete for safety. (00:25:55)
Continuity mistake: The position of Tim's hands change when he is about to leave the police station.
Visible crew/equipment: There is a fluffy mic visible in the car that Kat is driving when it crashes into the haystacks.
Revealing mistake: At the beginning of the film, even though the sky is cloudless and clear blue, the streets and highways are uniformly wet, as if a storm had just swept the area. Then, even though all of the vehicles on the highway are raising clouds of wet spray, none of the vehicle windshields are splattered with moisture, and none of the vehicles are using their windshield wipers. In fact, the only time we see a woman use her windshield wipers is when the guy throws a lit blunt onto the woman's windshield and it catches some dry leaves there on fire. So, in summation, dry leaves catch fire on the windshield of a car in spite of heavy road spray on a wet highway on a cloudless day. Multiple inconsistencies.
Character mistake: The guy on TV says all of the flight 180 survivors have died. That's incorrect as Clear is still alive and a main character of this film. (00:02:05)
Revealing mistake: When Rory gets sliced by poles, if you look close the poles can be seen hitting an invisible pole then bounce on the ground.
Visible crew/equipment: In the pile-up scene when Eugene falls off his bike and crashes into the log you can see what seems to be a crash pad. After he has fallen and hits the log, the bike crashes straight into him. If you look closely just above the log you can see the crash pad.
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.
Factual error: In the scene with the defibrillator it shows on the trace that her heart rhythm is asystole. Defibrillators only work with shockable rhythms i.e. VF (ventricular fibrilation) or pulseless VT (ventricular tachycardia). Using one on an asystolic patient would have no effect at all.
Revealing mistake: When Kimberly's car gets flipped around a bunch of times, the dummie's limbs flopping around are quite obvious.
Deliberate mistake: When Kimberly is being revived, it's obvious that they are using a defibulator. But when Kimberly finally comes to and is covered by a sheet, you can see she has a bra on. This is impossible to have because you need direct contact with the skin in order for it to work. And the machine would start the heart working if it was lower on her chest.
Continuity mistake: When Evan is coming home to his flat, look at the marbles near the toy ambulance. When the camera pans over it and later when Evan steps on one, their positions are different.
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.
Revealing mistake: When Kim's in the car explaining her premonition, she turns on the radio and the time is 8:24. When Officer Burke approaches the car, it's only a few minutes later. But later when Officer Burke, Kim, and Clear are checking the tape to identify Isabella's license plate, the time on the tape says 9:12.
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?
