Plot hole: At the end of the film Mardukas reveals that he has been wearing a body belt packed with cash - "in the neighbourhood of three hundred thousand dollars" - ever since Jack detained him in New York. Are we to assume that Jack Walsh, an experienced, hard-bitten ex-police officer, now a bounty hunter who routinely chases down violent and armed bail absconders who would kill him without a second thought, didn't even perform a perfunctory search of Mardukas when he detained him? This man used to work for the Mafia! What if he was carrying a weapon? A body belt with three hundred one thousand dollar bills in it would be uncovered by even the most casual pat down.
Suggested correction: He was using $1000 bills. That's 300 bills in the belt which spread evenly absolutely could have been missed near his waist as part of his clothing.
Rubbish. I specified $1,000 bills as that would be the smallest package he could have secreted about his person, and it would still be instantly detectable. If he used $100 bills the package would be ten times larger, and he would have to carry a rucksack under his shirt.

Revealing mistake: When they are at the Nutmar camp in the mountains, Val Kilmer tells Willow "Get on that shield!" but when they go over a 6, 7, 8 foot drop when they are sledding down the snow, you can clearly see runners on the shield.

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.

Revealing mistake: After Jim's horse is shot from under him while running down the really steep hill, and Jim later regains consciousness, before he turns and finds his horse dead, if you watch closely you can see the horse still breathing.

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.

Factual error: At one point in the movie the sun is behind the helicopter and we can see that the places for the missiles are empty. However, he's shooting right after that.

Continuity mistake: When MAC is blown by the helicopter, he lands on a man's windshield, and the man has to start dodging traffic. Between shots the traffic he is dodging changes. (00:10:45)

Continuity mistake: When Petri fell into the tar pit, there were two dinosaur skeletons, one on each side. When Spike, Ducky and Littlefoot went to rescue him, the skeletons were gone.

Revealing mistake: In the scene where the bodies are found in the river, Tom Berenger yells, "Sarah". As he looks down the river in the "wilderness" a logging truck can be seen driving down a road.

Visible crew/equipment: In the scene after the storm, the ship moves in the sand. Look at its front and you'll be able to see a wire that moves the ship. It's very visible.

Factual error: Johnnie Dodge wears no medal ribbons. Even if the real Dodge had not had the DSO, DSC and MC, it would be inconceivable that a major who had fought in two world wars would have no campaign ribbons.

Factual error: The sequence showing the moon is incorrect as it shows the Moon as it looks from the northern hemisphere. It should be inverted.

Revealing mistake: The "Great Train Robbery" actually took place on a two-track railway near Cheddington - the West Coast Main Line. However, the filming took place on the Great Central Railway steam line near Loughborough, which only had one track at that time. They laid a second track for the filming, but omitted to cut down a large tree at the end of the rails, which would block the path of a train. This is blindingly obvious, especially as they show this "atmosphere shot" twice. The tree is still there the second time.

Continuity mistake: When Pee-Wee and Winnie are having the picnic under the tree, he wipes a big gob of something from his face onto her dress. In the next shot, there is absolutely nothing on her dress.

Audio problem: When Bourne rescues Marie, he fires a silenced pistol at the man who was trying to rape her, but the sound is of an unsilenced gun. (01:01:10)

Continuity mistake: After Chuck Norris throws away the pimp during the initial evacuation of the embassy, the man pulls out a gun and shoots Chuck Norris from behind. The bullet hits him in the right shoulder but at the next moment - seen from his front - the wound is on his left side.

Continuity mistake: In life number 3, Uncle Todd wipes the blue paint ring from Garfield's face and then places him upon a pink dotted mushroom near two paint cans. But between shots, both paint cans disappear. (00:13:50)

Visible crew/equipment: When Guarino is being taken away by The Hunter, you can see the rope used to pull him in the upper right corner of the screen. (00:46:05)

Revealing mistake: When Jemma enters the headshrinker's laboratory, there is a table with three heads on it each encased in glass. When it goes in close-up on the middle head, you can see that the table has a hole where the actor can slip in his head.

Other mistake: Christina suggests that they have found Atlantis. However, they start in Hawaii, which is in the Pacific. The general consensus is the Atlantis is in the Atlantic (or Mediterranean) and not the Pacific. Some people do suggest that the lost continent of Mu is in the Pacific.
