Continuity mistake: When Grace runs into the diner bathroom, she pulls out several paper towels from the dispenser. After she has grabbed a handful you can see that half a paper towel is visible sticking out of the dispenser. In the next shot the paper has vanished and no towels are visible. (00:30:05)
Continuity mistake: After Ryder has been kicked out of the car, in the shot as he rolls to the ground in the background you can see the car driving off - and you can see Grace grabbing the door to close it. But in the next interior shot, Grace is still in the backseat and she then proceeds to climb into the front seat and close the door, again. (00:16:30)
Continuity mistake: When Jim and Grace start their car journey, Grace needs to go to the bathroom. During the conversation, as the shots change the position of the watch on Jim's wrist keeps changing, as does his head position (either looking at the road or at Grace.) (00:02:15)
Factual error: When Jim is driving the car and slams on the breaks just before hitting Ryder, the car is thrown forward - during all these scenes, although it is very rainy and windy, the raindrops run down the windshield as if the car is stationary. If the car was driving at a very fast speed and it is windy, the raindrops should be blown upwards on the windshield.
Continuity mistake: As Ryder is grabbing Grace by the face and pointing his knife into her cheek, during the whole scene as this continues, Grace's hair is repeatedly either covering her face or is pulled back under Ryder's hand. (00:15:10)
Continuity mistake: At the start when Grace is running across the campus to Jim, the items she's holding rearrange in her arms between shots (note the grey blanket which is over her left arm, then under her right.) (00:01:30)
Continuity mistake: When Grace is getting changed in the car, she pulls on a pair of jeans and then pulls her blue shirt off over her head. In the first shot she is pulling it over her left side of her head. In the next shot she is pulling it off over the right side. (00:02:20)
Continuity mistake: As Jim and Grace are driving down the road, a dragonfly splatters onto their windshield. Between shots the size and shape of the splatter changes, and continues to as Jim attempt to wash it off with a bottle of water. (00:03:35)
Continuity mistake: When Jim and Grace are driving away from the police in the stolen sheriff car, they are shot at and the back tailgate and left wing mirror are broken by gunshots. But in following shots you can see both parts of the car completely intact again, the broken, fixed, etc. (00:48:40)
Continuity mistake: When we see the dead bodies of Harlan and the policeman laying in the office as Lt. Esteridge is looking at them, you can clearly see the "dead bodies" breathing. (00:40:50)
Factual error: There are two instances when Jim and Grace are not wearing seat belts and are involved in big car accident scenes, but don't even fly forward from their seat an inch. The first is when Jim slams the brakes on and sends Ryder headfirst into the windshield. The second is when their car goes flying off the side of the road after dodging the lorry. (00:16:00 - 00:22:50)
