Continuity mistake: When the cow blows by the truck, the truck is driving down an empty dirt road with water on both sides. During the shots of the occupants, the road behind the truck is paved and dry. Also in one of these rear shots a truck (Red Chevrolet Blazer) drives by in the opposite direction. (00:42:25)
Continuity mistake: When General Grey tells the President not to engage until they have visual, in the President's close-up the exterior of this F/A-18 Hornet is quite different than what was shown in the earlier shot, as the canopy closed over him. All the rivets around the canopy have disappeared and the 'danger' triangle is much closer to the name Patrick, the seat differs, etc. Plus the fact that the canopy and hull are actually one unit in the second shot. (02:02:15 - 02:03:15)
Continuity mistake: When Sonic and Tails are fighting metal Robotnik, he shoots glue at Tail's tail. Tails says he can't fly to help Sonic, but when he gets the piece of concrete to surf across the water on you can see that his tails are not glued together.
Continuity mistake: Nick Cage is chasing Mason in the yellow Ferrari. The windshield breaks at least twice, but is perfect in the next shot. (00:45:55)
Continuity mistake: When Hale shoots into the train from the helicopter, he wounds Deakins in the right arm, but later during the movie, the wound is nowhere to be seen. Especially during the fight scene at the end when Deakins takes off his jacket. There's no blood or wound anywhere on his right arm.
Continuity mistake: In the scene where Picard, Worf and Hawk are outside the ship and want to separate the transmitter dish from the hull, Picard must move a kind of tube out of an console and must turn it from a low to a high position. In one shot the tube is in the high position, in the next shot it is in the low position and then Picard pulls it out and turns it in the high position. (01:06:40 - 01:10:35)
Continuity mistake: As paramedics inflate Jordan's assistant Stan Podolak following his lone bucket, the scoreboard shows the Monstars ahead 77-67 with 10 seconds remaining. Yet following his treatment and the surprise entrance of Bill Murray, the score has changed to 77-76 with no time having elapsed.
Continuity mistake: When they are in the Whitehouse, and Beavis has turned into Cornholio, he picks up the "Red" hotline phone on the President's desk, and is talking to the nuclear bomb officials. Later, when they are in the President's office again, getting their certificates, there is now a black phone on the desk, where the red one was. (01:03:05 - 01:11:00)
Continuity mistake: Sandy is fixing the deck with bare feet when Flipper knocks Sandy into the water with his tail, but as he is falling into the water, Sandy has black water shoes on.
Continuity mistake: At the beginning of the movie, Itchy comes to heaven in a teal colored shirt. When given a halo, he is in a blue shirt (the shirt is for heaven, but not given to him at that moment). When Itchy runs to Charlie right after that, his shirt is teal again. When Charlie tells Itchy he is dead, that's when the shirt changes to blue again (purposely).
Continuity mistake: When Harry puts Million Dollar Sticky on the TV, between shots Zinnia puts her sunglasses on twice. (00:18:45)
Continuity mistake: After he met the woman who helps them, Stephen Baldwin is wearing a shirt over his shoulders. In the very next cut, it is missing, but it reappears in the next cut.
Continuity mistake: In the same shot, note the top of the twin towers are in the clouds - its not a real nice day in NYC. But later when they're on the dock, there's not a cloud to be seen.
Continuity mistake: Besides the fact that during the final action sequence it is impossible for two trains to occupy the same tunnel, how is it that the blades of the helicopter attached to the first train don't strike the second? Tight fit.
Continuity mistake: When Bowen first catches up to Draco under the waterfall, he is completely soaked as he stands there and talks to him. Draco takes off flying and Bowen goes after him on his horse and is now completely dry, hair and all.
Continuity mistake: As the Doctor is being put to sleep, he lies on the operating table which has no pillow for his head. When Salinger uses the defibrillator on the Doctor, he has a blue pillow cushioning his head.
Continuity mistake: Throughout the scene where Jamie and Howard are in Jamie's room, as Jamie is drawing, keep an eye on his picture. It is inconsistent between shots.
Continuity mistake: Shortly after Jasper & Horace steal the puppies, a blue Renault 4 is seen going past the entrance to the mews. About 3 seconds later it goes past again in the same direction.
Continuity mistake: When the Presidents jump off the moving train, James Garner pushes Jack Lemmon off first, waits several seconds, then jumps himself. Given the speed and direction the train was going, Garner should have landed quite a ways away, to the left of Lemmon. But he ends up only a short distance away, to the right of Lemmon (based on the direction they were facing when they jumped.)
Continuity mistake: When the first FBI agent gets thrown from the passenger side of the car the scene is of a city street. When the second agent gets thrown from the car just seconds later after he hits the road the scene to the left looks grassy instead of city.
