Other mistake: On board the USS Reliant as it orbits Ceti Alpha 6 the systems panels show ship diagnostic diagrams including a wire model of a Constitution class hull, something the Reliant doesn't have. (00:13:01)
Other mistake: As Ray and Emma are drifting around San Francisco in the speedboat, they come across a Navy ship that just got carried in with the tsunami and is now leaning 20 stories high against a building with water dripping from it. If the tsunami were that high, with the wave having now receded back down to ground level, why are there still fires burning down low? The wave would have snuffed them out. (01:30:40)
Other mistake: The hurricane winds blows cars around, but the actors can walk against the wind and climb cellphone towers. Plus the hurricane "eye" hits the town, but trucks ride out on a road with dry leaves and dust.
Other mistake: In the first scene with Randy telling Jamie Lee Curtis to turn around, the reflection in the TV never mirrors the actual position of Jamie Kennedy. (01:22:30)
Other mistake: When we see the numbers for the coded entry to Alice's weapon, the order of the numbers is 1 - 2 - 3 - 4 - 5 - 6 - 7 - 8 - 0 - 9. The 9 and 0 are the wrong way round. (00:47:40)
Other mistake: When Memphis and Kip are hiding from Johnny B and his crew in the cafe following the ambush, Memphis devises a plan to make good an escape. He sends Kip out to use the tow cable on the heavy tow rig to destroy Johnny B's Mercedes. First angle shows a cable wrapped around a rear A-arm of the vehicle and the hook connected to the cable, the next shows a hook directly attached to the front axle, which is the one that gets torn from the Mercedes when the tow rig pulls away. Additionally, a different cabling rig and loose cabling used in the stunt are strewn behind the car. So even if Kip somehow made 2 connections without being seen or heard, the rear rig is different than the one shown in the first shot. (00:51:00 - 00:53:00)
Other mistake: When the main characters are in the motel and they hear the moth flying outside the window, Stu, the creepy deputy with the glasses, picks up a shot gun and racks a round into the chamber. In the next shot of all of people firing at the moth through the window, Stu is now holding his revolver and fires with it. When he runs of out ammo with the revolver he picks up the shotgun again and before firing racks the pump again. Since he already did that the gun should have ejected the unfired shell that was already in the chamber from earlier, but no shell is ejected.
Other mistake: When Jennifer meets David in Oregon she says she drove 3 hours to get there. In the next scene they are getting off a bus to catch the ferry. What happened to her car?
Suggested correction: There are possibilities off-screen as to why. It's possible that the bus used its own private road to get to the ferry which may be closed to the public, or the parking lot may have been too expensive and they parked on a street instead and caught a bus. It's not really known, but those are some possibilities.
Other mistake: Carolyn Stilton shoots Blondie O'Hara in the head and is lying dead over her dead husband. Just before the final scene starts she begins to open her eye.
Other mistake: Throughout the entire chase scene at the end, the vault creates sparks on the road. Yet when they get to the bridge, no sparks appear. This cannot be due to the vault being empty at this point, as the vault itself is 10 tonnes, as mentioned earlier in the film. (01:49:00)
Other mistake: When Fergus finds Jude in his apartment (the scene in which she has coloured her hair red), Jude unholsters her 38 cal. and one can distinctly hear her cock the hammer. At the end of the scene, she places the gun in her purse with the hammer uncocked.
Other mistake: On his own computer, Sean looks up his son's file, which states the boy died immediately and his date of death was September 9th, 1991. When Eve and Castor (as Sean Archer) are at the cemetery, the date of death on the headstone is September 24th, 1991. (00:21:15 - 01:14:50)
Other mistake: At the taxi cab chase at the end, you can notice when the car is a real one and when it's CGI. Note how the real car has scratches and other things on the front of it, but the CGI car, if you look closely, has almost no imperfections, and even if it does have some, it doesn't match the real car one bit. You can see these things when the car drives off his mouth or when you see Godzilla running behind.
Other mistake: When Sulu tells Kirk he is coming to help, he states the Excelsior is currently in the Alpha Quadrant. The problem is the the Alpha Quadrant in the Star Trek universe is one quarter of the total Milky Way Galaxy. While technically correct, Sulu giving his position as in the Alpha Quadrant is useless to Kirk in terms of knowing when to expect help. It doesn't matter where Khitomer is in the galaxy. Sulu saying he is in the Alpha Quadrant gives Kirk absolutely no idea of when he will arrive. He could be anywhere from 5 minutes away to 5 weeks away or even further. Remember, it was originally projected to take Voyager 70 years to go from the Delta Quadrant back to the Federation in the Alpha Quadrant.
Suggested correction: The implication is that Excelsior has only very recently crossed the border from the Beta Quadrant to the Alpha Quadrant.
Even if that "implication" were true (and there's nothing dialogue-wise to indicate such) it's still useless to Kirk as to when the expect help. The dividing line between the Alpha and Beta is fully half the width of the galaxy.
Sulu doesn't expect Kirk to deduce where the Excelsior is, he tells him directly that they're unlikely to make it in time, and the reason is that they are "now in Alpha Quadrant" i.e. they were previously not in the Alpha Quadrant, i.e. they're far enough away that recently they were in a whole other quadrant of the galaxy. (I agree it's an awkward line, but it makes sense if you think of it like "I'm now in the U.S." if it's known you already live there - it means you've just returned).
Other mistake: While flying the helicopters, notice that the human pilots are not wearing protective masks in an open cockpit with the cargo doors wide open as the Avatars are either hanging out of, or staining to see past the pilots.
Suggested correction: This has been submitted and corrected three separate times. The cockpit is sealed off from the outside.
Baloney. The movie made several egregious errors involving the use of masks. In several scenes you see them not wearing masks in human form including going into the lab at the floating mountains. Everyone including Trudy should have been dead within minutes.
Other mistake: In the 15th minute, in the scene where the two gangsters first spot Michael Douglas, one is smoking a cigarette and smokes it backwards. The tan filter is visible on the end of the cigarette.
Other mistake: At the end of the movie, when the president gives a speech, Mike Banning's face still shows the unhealed cuts from his fights at the White House, suggesting that this is only a couple of days or so after the event. However, the President, who was shot in the gut and on the verge of dying, is completely recovered.
Other mistake: Rusty's attorney challenges Dr Kumagai by pointing out that Caroline Polhemus' had had a tubal ligation, but the spermicide nonoxynol-9 was found in her body. Kumagai is caught off balance, totally flustered. In fact as an experienced medical examiner Kumagai would know that at that time nonoxynol-9 was thought to offer protection from HIV and was widely used by people at no risk of an unwanted pregnancy. He would have thrown this right back in the attorney's face.
Other mistake: After the veterinarian throws blood all over the floor, we see clean spots appear on the floor in the shape of Sebastian's feet as he walks through the blood. Somehow he never has any of it stick to the bottom of his feet (even when he's in the puddle).
Other mistake: Near the end of the movie, after the cops storm the bank, all the cops walk into the vault, and as the camera follows them into the vault, you can hear the camera hit the metal vault door, and visibly see the camera shake from hitting it. (01:38:15)
