Continuity mistake: After crashing through the guarded barrier of the base, David drives the stolen pickup truck and burning debris from the electrical storm falls onto the hood of the truck. In the next close-up the burning debris is shaped differently. Then after they crash through the wall, in the wide shot there is no burning debris on the hood. Yet, in the next close-up there's plenty of burning debris, but then in the next shot there is no burning debris again, just a smoking engine. The building debris surrounding the truck and behind it, in the first shot differs from all the building debris in the second shot as well.
Continuity mistake: When Dr. Longstreet, in 1984, is in his office, in the wide shot the rolodex is near the telephone and papers. In the close-up shot of his desk as he sits down, the rolodex is not there. The globe on the file cabinet also shows different continents in the close up than the wide shot.
