Continuity mistake: Dr. Longstreet, in 1984, is in his office near the black file cabinet. Before he gets the files on the U.S.S. Eldridge, in this shot the plant is right next to a set of files on top of the cabinet. Once he removes the files he wants from the drawer, in this shot the plant is at the wall, further away from the files up on top. (00:32:50)
Continuity mistake: After Allison's car rolls down the embankment, in the first shot there is no snow on the roof of the car. In the close-up of the car, as the police draw their guns, there is now snow on the roof. (00:35:05)
Continuity mistake: When Dr. Longstreet approaches the scene of the chopper accident, in the wide shot his scarf hangs straight down. In the next close-up, his scarf is folded one end over the other. In the next wide shot, his scarf hangs straight down again. (00:22:15)
Continuity mistake: As Allison drives searching for David, who's on the run from the MP's, the windshield wipers are on. In her two close-up shots in between, the wipers are not on. (00:45:55)
Continuity mistake: David and Jimmy are running from the military helicopter, when they run into an electrified fence. Jimmy actually hits it and in the first shot he grabs hold of the fence with both hands, then he *removes* his right hand only to put it *back* onto the *electrified* fence. In the next close-up shot, Jimmy is standing at a different place along the electrified fence, this time right near the pole and Jimmy's left hand is now lower on the fence than it was in the previous shot. Then in the next back shot, Jimmy's left hand is higher up on the fence again. (00:17:05)
Continuity mistake: David and Allison pull up to the corner across the street from David's father's old place. In the close-up of them in the car, the surrounding area around the car is completely different than the area shown around the car in the wide shot. Also in the wide shot we see cars parked to the right of the screen. After crossing the intersection, they pull into his father's old place, and we see the same sidewalk across the street, but none of the cars that were parked there in the previous shot are there now. Then when they pull away, again the parked cars are different. (01:02:20)
