Best action movie mistakes of 1988
Visible crew/equipment: In the first scene of the Christmas party when Takagi steps out of one the offices and greets a couple of his guests, the camera pans left to show the orchestra and other guests. A huge shadow of the camera and its operator is being shown on the back wall, then the stage light gets moved to light a different area and the shadow is gone.
Continuity mistake: While this movie is so bad and full of mistakes, its barely worth finding them all, one stands out in the history of movie mistakes. One of the officers on board the ship, Lt. Lamont, is killed by the villain. A few scenes later she shows up on the bridge as an extra.

Continuity mistake: There is a scene where the kids are being chased in a speedboat, while mortars are being launched at them from behind. One shot is of the young boy looking at an incoming mortar over his right shoulder, yelling "Look Out!", and then seeing the mortar hit on the left side of the boat.
Continuity mistake: When Jack and the Duke are in the restaurant car of the first train, Jack is eating a chicken leg in one shot. In the middle of a sentence he changes to eating jelly and ice cream, which he finishes. In the very next shot his bowl is full of jelly and ice cream again.
Continuity mistake: Opening scene where Chris Sarandon is chasing Brad Dourif into the toy store. During the gunfight, Sarandon has gloves on. As he enters the store he is wearing gloves. The next shot, the gloves are off. The next scene, the gloves are back on and he takes them off by biting the fingertips and pulling them off.
Revealing mistake: Any time when the two girls are in hell's corridors and running around, you see these corridors as stone walls, yet whenever they back up against one of these walls, you can clearly see they are merely rubber sheeting overlayed on a framework as the rubber sheeting bends and contracts very clearly.
Factual error: The soviet military equipment isn't all that Soviet ... e.g. the helicopter is supposed to be a "Mil-Mi 24 Hind" (Pilot and system operator sitting behind each other), in fact it's just a French "aerospatiale puma" with additional mock turrets and so on (crew sits side by side).
Revealing mistake: As Reg fights with one of the baddies with the chainsaws, as the baddie take a swing with the chainsaw he misses and cuts into the wooden door. You can clearly see that a vertical cut has already been made in the wood though, to help the chainsaw get in and cut.
Revealing mistake: We know that the blob dissolves flesh and hair and that it can also burn wood (since fluid coming from the blob burns a small spot on the desk in the hospital) and that it can dissolve bullets, but despite this obvious acidic state, the blob doesn't dissolve plants, walls, glass, concrete, metal, nor sticks and twigs.
Other mistake: As the murderer spots a police car coming towards him he turns to his right onto a dirt road, there is a huge boulder at the point where he turns, marked "No trespassing, Bishop Falls camping". As he turns he sideswipes it, rocking the boulder, however the sideswipe has no effect on his vehicle.
Plot hole: When Gary Busey infiltrates the Mexican terrorists' compounds, he first throws a stick to distract some guards and kills them. A few minutes later a terrorist officer reports to his boss that Gary Busey has killed three of his best men. Are we to believe that the three best terrorists were tricked by a stick thrown into some bushes, and then easily killed by an unarmed assailant (they had submachine guns)?
