Revealing mistake: When the officer is looking at the pictures of the Flight 180 survivors and their deaths afterward, notice that Todd is shown still struggling at the ropes and looking into the camera. Apparently the media thought it would be better to take a picture of Todd as he was committing "suicide". A similar incident occurs with the bus accident picture. The girl is obviously splattered in the first movie, but appears to have mostly leg damage in the pics.
Revealing mistake: During the beginning crash sequence, you can see the tubes that fire a log in order to flip the cars. When the Mustang flips, you can see the flame from the charge in the tube. The red SUV has a visible flip tube as well.
Revealing mistake: When Nora's son gets killed, we can see the boy under the falling piece of glass. But in the shot where this piece is just about to smash him, you can see on the DVD edition that there is a dummy instead of him because his arms are too long relatively to the whole body and also the hands are obviously not human. (00:41:20)
Revealing mistake: At the beginning of the movie, (outside Kimberly's house when she says, "We're gonna go meet the guys") one of the extras in the background (he is clipping the hedges) keeps looking at the camera. [This was pointed out on the DVD].
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.
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)
Revealing mistake: When Kimberly's car gets flipped around a bunch of times, the dummie's limbs flopping around are quite obvious.
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.
Revealing mistake: When Tim runs into the pigeons and the glass falls: when it crushes him, you can see the arm bend backwards, same with his hand. When he gets snapped in half, the blood is water with some red food coloring stuff, not real blood. It is obvious that Tim is a rubber dummy. (00:43:09)
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.Charles Austin Miller
