Revealing mistake: When the shark is on the deck of the Andrea Gail, you can see the equipment underneath it that is making it move. (00:47:30)
Revealing mistake: During the war flashback there is a newspaper photograph with Captain Junuh on the shoulders of Savannah's young men. When the camera zooms into his face you can see it's someone else's, only in close-up it switches to Matt Damon's. This is surprising because in all other newspaper pictures Matt Damon is nicely worked in. (00:06:15)
Revealing mistake: When Alex drops the cigarette lighter to ignite the gas, you can see the flame is started from a different source, as it starts on the other side of the screen, a fair distance away from where the lighter landed.
Revealing mistake: In the bowling alley scene where Jeremy and Nick are discussing the red-haired woman, you can see Nick shaking from laughter and even hear it. It is easier to spot if you have watched the outtakes. Nick simply could not contain his laughter during this scene and so they just shot him from behind and left it in. This happens in another scene as well, when they first enter Jeremy's "manly" den. These two were just having too much fun filming this movie. Watch the outtakes.
Revealing mistake: When the group of journalists is heading to Vukovar, they are stopped and go to hide because fighters are bombing the town. At one point, the camera moves and the airplane moves with it.
Revealing mistake: When Sarah and Gretchen share the shower with Sebastian, you can see flesh-coloured underwear on their hips, to protect their modesty. (00:35:00)
Revealing mistake: All of the earthquake scenes are badly staged (since they were accomplished by the very low-budget technique of shaking the camera). Nothing except the actors ever falls down save for the occasional large object to grab your attention. This is most obvious in the scene at Saffron Burrows's home, as there are many things that should have been knocked over (lamps, vases, etc.) which are still standing upright despite many large shocks that have already occurred.
Revealing mistake: Towards the end of the film, when Parker and Longbaugh are coming to get Robin, they get in a small (by comparison to the end of the film) gunfight with Jeffers and the unnamed pimp. During the gunfight, Longbaugh empties two magazines through his 7.62 Galil trying to get Jeffers through the wall. However, the guy setting up the squibs must have been short of creativity, because the resulting yardstick straight line of holes would be virtually impossible to make with a 7.62 on full auto.
Revealing mistake: After Brashear surfaces with the re-captured nuke and it is being hoisted aboard, the mast line snaps and slices Brashear's leg. At the very moment the piece of metal cuts him, you can see the pant-leg switch from tan to white and back to tan.
Revealing mistake: At the 'beginning' when Teddy and Leonard drive up to the abandoned building with the old truck out front, inside the truck Leonard handles a number of .357 revolver calibre bullets that have apparently not been fired, but you can clearly see the indented primers in the base of the bullets, indicating that they are just inert movie props. (00:04:40)
Revealing mistake: When Roro is fighting Yasmin's brother in the car, he uses the handbrake, and the angle change to view from the top. You can then see a lot skid marks on the road where they did this stunt in previous takes.
Revealing mistake: When Jessica's dead body is seen by Annie in her bath and then in the hall, the make-up that is keeping Jessica's eye shut is coming away around the edges.
Revealing mistake: Sebastian Caine wears a latex mask and latex gloves in order to appear near-human. The mask he wears is fairly long, and covers his neck, and the tops of his shoulders and collarbone. However, there is a scene in which Linda and Matt are helping a nauseous Sebastian reach the toilet, where he vomits (invisible fluid) into it. In this scene, when Sebastian breaks free from them and runs to the toilet, we can see that his arms and chest are also visible, skin-colored. The mask he wears only reaches the very base of his neck, so it is possible that the actor playing the invisible man did not realize that the tops of his arms and chest were visible. (00:49:20)
Revealing mistake: Whenever someone takes drugs and their pupils "dilate" you can see that it's a normal eye being distorted by a computer because the arc of reflected light also is distorted.
Revealing mistake: When Trevor is stabbed, we can see the knife isn't in him, it's just pressed against his shirt.
Revealing mistake: When Patrick opens his fridge to offer Jean some sorbet, you can see the decapitated head of a woman in the fridge. If you pay close attention, you can see the head is moving a little. (00:59:36)
Suggested correction: It's a prop head resting on a freezer shelf. It could simply be that opening the freezer door causes the head to sway a little, similar to if you had an egg, lemon, or something else that didn't have a flat bottom resting on a shelf inside a fridge.
No, the way it was filmed was with the actual actress putting her head up through a hole in shelf. It's her head moving.
Revealing mistake: When Ed falls on his belly and dies of a heart-attack at the end of the film, if you look closely, you can see the actor is still breathing a few times. He's trying to hold his breath, but every so often, you can see his back subtly raise and lower as he slowly takes a breath in and out.
Revealing mistake: In Thomas' first appearance, he has no cab doors. He continues to not have cab doors throughout the movie except for a few shots.
