Continuity: In the scene when the Jeep blows the tire, the camera angle clearly shows the right front tire as being flat. The next shot with the sparks, they are coming from behind the camera. In the shot showing the Jeep spinning around, all four tires are inflated.
Continuity: During the jeep crash, in one shot the jeep is being pushed to the left and in the next to the right.
Continuity: Before the title sequence, when the tire of the Jeep explodes it sends the Jeep into a skid. We see a semi trailer approaching, and the driver of the truck applies the brakes hard enough to cause the trailer to jack-knife (this is shown quite clearly and dramatically). In immediately subsequent shots, however, the trailer is shown braking straight and true and there is no evidence to suggest that it was sliding sideways, but it is impossible to recover from a skidding jack-knife without stopping completely.
Continuity: After the truck hits the jeep near the beginning of the movie...the jeep is pushed out of its way twice in succession. No separate camera angles are obvious.
Revealing mistakes: When Julie is taking photos before the Jeep crashes, we can easily see that the camera lens is shut.
