Continuity mistake: During the Jacob's Ladder demonstration, the classroom clock remains at 8:10 throughout most of the scene. Then, in several brief flashes, it's 8:15, then 8:10 again, and finally 8:13. (00:32:00)
Continuity mistake: Early in the movie when Thomas falls overboard, John Smith ties a rope around his waist (00:02:56) and jumps in after him. Thomas is very far away from the ship (00:03:12). But when the men pull John and Thomas up, John is holding on to the rope with one hand and the end is left dangling (00:03:36). One of the men who pulled them up then coils the rope with a mere two coils (00:03:48), not nearly long enough to have reached Thomas while he was overboard. In the same scene, when we are viewing the men pulling John and Thomas up from above (00:03:38) there is no extra rope at their feet as there should have been for such a long rope.
Continuity mistake: This is the car chase scene, where Ralph Fiennes and Angela Bassett are in a limo being chased by two bad cops in a pickup. Early in the scene, you have the view from inside the pickup when it rams the limo from the rear passenger side, and you can clearly see bullet holes in the glass and rear of the limo (no weapons fired yet). Then a few seconds later in the scene, you can see the rear of the limo with no damage. Moments later, you see one of the cops firing an automatic weapon, and subsequently witnessing the holes being made in the limo.
Continuity mistake: When Amanda is about to die, she gets dragged by the corn plants and they pull her shoes off. But then when she is running away she has her shoes back. Then when she slips on the pole she has socks on. (00:43:30)
Continuity mistake: In the scene when Junior cuts the tree with his chainsaw, when he looks up to see how high it is, we can see it has branches. In the next scene when the tree falls on Scoutmaster Flimm, it doesn't have them at all and is cut straight at the top. (00:29:40 - 00:31:00)
Continuity mistake: In one scene someone is smoking a DuMaurier Canadian cigarette which was taken from an American cigarette package.
Continuity mistake: When the school janitor jumps from the roof then falls on a parked car, his head is turned to the right and it's obvious that it's a dummy. Two shots later, when Dr. Chafee puts his hand on the neck to take a pulse, the head is turned to the left and the body has changed position.
Continuity mistake: There is a color change on Darkman's burned skin. In the beginning of the movie, in his lab, his burns are pretty much flesh colored. Later on in the movie, they are a much darker red and brown.
Factual error: When Lt. Lee shoots down the second Messerschmidt in Italy, you can see it is a twin engine plane.
Other mistake: Soon after Dan Ackroyd makes John Candy translate all the phrases spray-painted on the van into French, you can see them driving on the road and all the spray-paint has gone. Then later in the film it reappears and stays for the rest of the film.
Continuity mistake: When Steele is falling down the cliff with Jenna's bandana in his mouth, right before he hits the bottom, the bandana turns white.
Continuity mistake: When J-Bone is coming down from Heaven, the lift he's on stops quite a way off the ground, and moves when he steps off it. Yet when he, Johnny and Jade step onto the lift, it seems to be on the ground as it doesn't move. It couldn't have been lowered, as we would've heard the noise of the motors.
Continuity mistake: Chris O'Donnell and Drew Barrymore are leaving the small town of Truth or Consequences, New Mexico, and they show the outskirts of the town as White Sands, when actually White Sands, New Mexico is about 2 hours away.
Continuity mistake: When Jimmy The Saint brings the cop to the "Man With The Plan" he starts yelling and one of the henchman raises his hand to Jimmy to stay calm and then he puts his hand down. The camera angle changes to a shot from the back and the henchman still has his hand up and Jimmy is saying his next line.
Revealing mistake: After Lucifer kills Gabriel, we get close-ups of Lucifer where the outline of his contact lenses are visible.
Visible crew/equipment: In this shot, Tim Roth is talking on the phone. In the background over his left shoulder you can see a crew member walk across the background. This takes place over about 4-6 frames on the DVD. (01:06:20)
Visible crew/equipment: When Christopher Walken throws Johnny Depp through the balcony, you can see the equipment which controls Depp's fall.
Factual error: When Napoleon is up in the air in the basket held up with balloons, you can see the Sydney Harbour Bridge, however on his adventures, he goes past Eagle Rock, which is not near the city. Also he meets a Frilled-Neck lizard, which is found in a different state to Sydney.
Continuity mistake: As Holly and Abe kiss through the cell bars, Abe goes from crouched, to straight-backed to crouched again.
Continuity mistake: Charlegrande stabs von Trotta in his right eye, but in all later scenes it is the left eye that's missing.
