The Philadelphia Experiment (1984) - 4 major mistakes

Continuity: 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: Aboard U.S.S. Eldridge, during the experiment's mishap, in the generator room David has his sleeves rolled up high on his arm, way above the elbows. In the next shot when he and Jimmy run to the top deck, his sleeves are at his elbows.

Continuity: At the hospital, as David walks up the corridor clutching his hand, he passes a nurses' station that has a plant at the corner. In the next shot, as he starts to run from the MP's, now there are two books under the plant.

Continuity: 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.
