Other mistake: When Somerset goes back to the man's house alone, he cuts a sticker on the door with his switch-blade to get in. The first error is the sticker is on the inside and it says "Keep Out." The best part about it is the door opens inward. How did they put the sticker on the inside and then exit? (00:20:45)
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: After the post-bank robbery shootout, a TV reporter is heard describing the shootout as taking place in a "small southland neighborhood." But earlier one of the detectives was heard ordering road blocks at Flower and Figueroa, meaning the gun battle occurred in Downtown Los Angeles. Hardly a small neighborhood.
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: At the end of the first movie Rybak is a Chief (E7), and he is a retired Lieutenant (O3) during this movie. Assuming he got commissioned to Ensign (O1) immediately after the events of Under Siege, it would take a minimum of 42 months to be promoted to Lieutenant. This movie takes place within 4 years of the first movie, because Admiral Bates is still the Chairman of the Joint Chiefs of Staff. The picture of Rybak in his Lieutenant uniform is at least 5 years old according to his niece. None of these timelines make sense for the rank he is in the movie.
Other mistake: When Robert the Bruce returns to the battlefield at Falkirk, there are 2 children supposedly crying over a loved one. If you look at the blonde girl she is actually laughing. (02:12:00)
Other mistake: When Michelle Pfieffer hands out menus for the restaurant in the class, they all read them out loud in English. Then when she takes Raul there, he says he can't read it because it's in French.
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: When Johnny Cage is fighting Scorpion in the forest, after Scorpion unleashes his snake-like spear from his hand but before the camera switches to Johnny, you can see the spear move down and it appears to be coming out of his forearm. Also the hole in Scorpion's hand from the spear is now gone.
Other mistake: In the scene after De Niro's car explodes, they show him being put in the ambulance feet first. Patients are always put in head first.
Other mistake: The bear is lit by a flashlight before Cole actually picks the flashlight up.
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: Nick Cage is playing blackjack at a Caribbean stud table.
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: When Ivan Ooze gives out those slimes to the kids, that boy is at the very back of that big crowd. As Ivan Ooze starts giving them out, it switches to the boy and he already has some slime, but it would have taken a few minutes for him to get one. (00:42:00)
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.
