Other mistake: When Rex shakes the table causing the baby monitor to fall, the batteries fall out and we see the open battery compartment with markings for positive (+) and negative (-), and space for two AA batteries. Woody jumps off the bed and places the two batteries inside the compartment, but before he closes the compartment note the position of the battery closest to the top of the monitor. The positive side is actually where the negative side should be so the monitor should not work, but the monitor turns on just in time to hear the soldier's warning. (00:13:15)
Other mistake: When Josh and Cher are driving home from a party, they show a shot of the car. It's a blue sports car that passes a Hertz car rental sign. When Elton is driving Cher home from the party in the Valley, they show the exact same shot of the blue sports car passing the Hertz car rental sign.
Other mistake: In the scene where Robin Williams tells Sarah that she needs a 12 to win, she rolls a 3. The next time she rolls, Robin tells her she needs a 7 to win.
Other mistake: Whenever Helen Hyde turns back into Richard Jacks, none of the clothes ever seems to rip or stretch - they both have different body types.
Other mistake: The Magic Eye Picture that Willem is looking at throughout the movie is NOT a sailboat. If you pause the movie and find the image it's actually three rows of 3D shapes.
Other mistake: George and Nina are sitting in the kitchen when the ceiling leaks from the rain and George makes a comment about the roof leaking. The only problem is it is a two-story house, so the water must be coming from the floor above, not the roof.
Other mistake: The fax machine Hoggett receives as a gift is different from the one he uses to send his application for the show.
Other mistake: When the bad guys are stealing the drugs and they use the spray to break the lock, they drag the chain off the bars, and if you look closely you can see part of the bar chip off and it's made of wood. (00:08:10)
Other mistake: During the drill performance towards the end, the cadets' rifles bounce around like rubber, but you can hear the sounds of a hand hitting a real weapon from time to time.
Other mistake: This error occurs during the scene in which the President and Lewis Rothschild are riding in the limo, just after the President has broken a date with Syndney. The background scenery, visible through the windows of the car, is noticeably in slow motion, even though the car (and the people inside it) are moving at regular speed.
Other mistake: When the guy is on the balcony, and gets shot over the rail, you can clearly see the top rail bend to let him flip over and fall. Then when he lands you can see what looks like the corner of a mat lift up and kick dirt up. The next shot shows the bad guys leaning on the very rail that just bent.
Other mistake: In the scene where Sophia Loren leaves the bar, Ann-Margaret sees her and calls her Lydia. Sophia's character's name is Maria. You can see this on the VHS only because it is corrected on the DVD.
Other mistake: During a chase scene with the hovercraft near the waterfront in NYC you can see mountains in the distance. Not in NYC.
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.
Other mistake: When the girls are in the diner and Chrissy is counting money, you see a picture of the tree house in a tree, it is the same tree as the one the girls use after they buy the tree house.

Other mistake: When Smokey and Craig are sitting in Craig's house, they get paranoid when Dana's friend knocks on the door. Later Craig's father parks in the driveway only a few feet from the open window where Smokey is sitting, yet they only seemed surprised when Craig's father enters the house.
Other mistake: During the scene where Luc and Kate first meet on the plane and are talking, Luc gets up to go to the bathroom (the second time). When he returns to his seat, the plane has landed, Kate is sleeping, and the other passengers are deboarding. There's no way he would have been allowed to remain in the rest room during a landing.
Other mistake: When they are trying to figure out who the vampire is and they hold a ball and then they pull down a curtain and reveal a mirror it is obvious in the reflection that Mina has no partner and when they do their "finale" when Dracula is lifting her up it is obvious Mina has some other support that will continue to turn her after she is shown in the mirror while the vampire has no reflection.
Other mistake: When Wallace sees the meat mincer, he says 'Now that's clever', but on the English DVD, the subtitles say 'Now the fat's cooked'.
