Revealing mistake: During the scene at the restaurant in Montenegro (actually filmed in the Czech Republic), you see a payphone with a Czech Telecom logo on it (itself a piece of history, as these are all now rebranded O2). (01:57:50)
Revealing mistake: When Eric Matthews is smashing his foot, he hits it the first time and it shows a close up. If you watch the small amount of blood when he hits it again they have used the same shot. (00:04:00)
Revealing mistake: In the disco scene, the DJ is playing music, but the Pioneer decks and the DJ Mixer are not even turned on, as no lights are showing.
Revealing mistake: During the final conversation between Detective Frazier and Arthur Case, Frazier holds up his hand with the ring on his middle finger. It is pretty obvious that the hand was inserted into the scene in post production; the hand doesn't move in a natural way and simply looks out of place.
Suggested correction: Really? I don't see anything unnatural in the hand's movement at all. Doesn't look at all obvious to me that it was inserted in post-production. After all, Frazier refers to "this ring." They will want it in shot so I'm sure they made sure Washington held it in shot.
Yes, really. Look again. Look at how it moves down and vanishes out of the frame. No human hand moves like that! They didn't have Washington hold it up for the shot and it was inserted later as a pickup shot. See this IMDB goof entry for more details: "During the final conversation between Detective Frazier and Arthur Case..." "a picture of a hand with a ring on the middle finger was inserted into the scene - first moving up into the shot, and then moving down off screen."
Revealing mistake: When Costello's men drive off, after throwing Queenan off the top of the building, the state troopers are firing at the van. One back window is shot out, then in the next shot of the van the other window is shot out and then the same one is shot again so the one window is shot out twice in the same scene.
Revealing mistake: In the scene in the laboratory under the mansion, when Wolverine confronts Jean about Cyclops, there is a close up shot of Wolverine's hand holding Cyclops' glasses. In this shot there is a small cut visible on Wolverine's hand - his healing power should not allow this.
Revealing mistake: When the truck leaps off the ferry, the underside is seen, exposing the still-flaming 'roll cannon' opening in the rear floorboard. This cannon is what caused the rear of the truck to rise, sending the truck flipping through the air. (01:52:30)
Revealing mistake: When the children run along with the car waving, you can see a modern digi-watch on the wrists of one of the children, which was not produced during the 1970s.
Suggested correction: Without using slow motion of freeze-framing, how can you tell it's a digital watch? It certainly isn't clear on the DVD version.
Revealing mistake: Just as the bus begins to roll down the mountainside, cables are visible which were holding the bus in place. Most easily seen during the first complete rollover. (00:05:45)
Revealing mistake: The money that the two gang members are counting in the opening view of the hotel room scene is obviously fake. Notice how white the bills are, when they should be greener and have more of the random anti-counterfeit features. (00:02:00)
Revealing mistake: In the helicopter chase Ethan and Lindsey (and the defibrillator) are just sitting on the floor of the helicopter while it is doing very radical moves. They would have been thrown around.
Revealing mistake: In chapter 14, Bill Cox calls Harry, who's asleep in bed. Harry answers his flip phone, but doesn't flip it open. (00:54:50)
Revealing mistake: The roller coaster used for the Devil's Flight is really the Corkscrew at Playland in Vancouver, where all three movies were filmed. If you look during the opening credits, you can see the name "Corkscrew" up in the lights above the coaster. After this, it says Devil's Flight during the rest of the roller coaster scenes.
Revealing mistake: Near the end, when the captain is walking out of the labyrinth holding the baby, you can tell it's a dummy. The baby does not move in the slightest, you can't even see it breathe.
Revealing mistake: When one twin (presumably Alfred) is removing the other twin's fingers, "Alfred's" upper arm passes through his twin's head as "Alfred" reaches for the hammer. [Fixed on DVD.]
Revealing mistake: When Robert Thorn and Keith Jennings are opening the graves, they are sitting and kneeling on the snow-covered ground. However, none of the snow clings to their clothing, and Roberts light trousers do not get any wet spots on them from the snow, revealing that the snow is fake.
Revealing mistake: In the scene where Rose shines the flashlight down into the mine shaft, the light from the flashlight can be seen reflecting off of it, as if the lava down in the shaft is just a picture (or on a green screen).
Revealing mistake: When Selene falls into the tunnels of Tanis's lair where the lycans are, you can see the pad she lands on. It's almost passed off as falling snow, but watch how as she lands the 'ground' squeezes like a pillow. This was pointed out in the director's commentary. (00:44:00)
Revealing mistake: When Jack drives the bus down the alley, it knocks a series of A/C units off a building. The last one comes open and there is obviously nothing inside. (01:12:35)
Revealing mistake: As Bobby and Brenda are loading the bodies into the van, Lynn can be seen breathing.
