Continuity mistake: During the spectacular car chase David Caruso's car is speeding through the streets jumping 10'-15' feet in the air. On one of the landings in a wide shot, you can see that an air bag deploys, but in the next close up of him in the car, it's not there.
Factual error: At the ball, in 1957, they play Eddie Cochran's "C'Mon Everybody" which wasn't written until 1958.
Visible crew/equipment: As Sean Connery is by the stairs in Ed Harris' parents' house, a camera is visible moving into the room to the left of Sean Connery. (01:27:15)
Continuity mistake: When Greg Kinnear is punching Harrison Ford he hits Ford´s shoulder, but Harrison Ford is taking his hand up to his face like he was being hit there.
Revealing mistake: After Richard has accepted that he will be king, he appears before a large assembly. Several of the soldiers standing by the walls are obviously plastic dummies. They have unnaturally smooth and blank facial features, and when you can see their hands, they are not grasping their guns, but merely holding their hands stiffly out with the gun between them.
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: In one scene someone is smoking a DuMaurier Canadian cigarette which was taken from an American cigarette package.
Factual error: When Lt. Lee shoots down the second Messerschmidt in Italy, you can see it is a twin engine plane.
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.
Visible crew/equipment: When Christopher Walken throws Johnny Depp through the balcony, you can see the equipment which controls Depp's fall.
Continuity mistake: As Holly and Abe kiss through the cell bars, Abe goes from crouched, to straight-backed to crouched again.
Continuity mistake: When the Colonel finishes talking to the General on the phone, he practically throws the phone into the army truck out of frustration. In the following shot, you can see the soldier in the truck with the phone in hand, as if it was calmly given to him, even as you hear the end of the "clunk" from when it was thrown. (00:52:50)
Continuity mistake: When Po is killed by the NVA it is the middle of the night, Captains Cahill and Doyle are close enough to the village to hear the shots and rush back to the village but as they enter the village it is early dawn.
Other mistake: In the scene around the camp fire, Rob Roy can be clearly seen with with plasters on his hand.
Revealing mistake: After Nicole has showered and she is getting out, you can see that she is wearing underwear as she is stepping out, to protect her modesty.
Continuity mistake: Becker is the last to go through the hatch into the NEB bunker, but when the camera switches to the view inside the bunker, Becker is seen already on the walkway while the others are still climbing down the ladder.
Continuity mistake: In the opening football scene, when Angus makes a tackle, the football clearly falls to the ground. In the next shot, however, it is seen soaring through the air.
