Deliberate mistake: When MIB agents exit the lift to get into the main hall of the MIB Office, the lift opens halfway up the wall and they need to go down a little platform. But when K and J return during the lockdown and face the trashcan with guns, the lift opens at floor level, so it can be conveniently peppered with bullets. (01:02:05)
Suggested correction: The building is in lockdown so it is no surprise that the lift is changed to a less flamboyant version. Even in the first scene, there are some doors there.
Deliberate mistake: At the beginning and especially at the end, Julianna Margulies spends extensive time in the ocean, wearing nothing but cargo pants and a T-shirt. Considering the movie takes place just off the Bering Strait, wouldn't she have quickly frozen to death? (01:21:05)
Deliberate mistake: In the scene after the Helm's Deep battle, when Aragorn meets Eowyn, the earlier footage of Aragorn's return to Helm's Deep is used. He has the wound on his shoulder and is dressed like he was during the 'falling' episode. The background (people in the fortress walking calmly) also indicates that this takes place before the battle. This scene should immediately follow the one where Aragorn is greeted by Gimli ("you are the most reckless man I ever knew"). Confirmed on cast commentary, extended DVD. (02:45:20)
Deliberate mistake: In the first scene Velma gets sprayed by the hose and slips but gets her foot caught on the chain; hanging upside down, but her skirt doesn't go "up". Deliberate to maintain the "family movie" tone. (00:02:40)
Deliberate mistake: When bars are placed on Harry's windows, so he does not escape, it is apparent that his windows have complete leaded panes of glass. Yet when Harry is being rescued, Ron and Harry speak with each other, even in low voices, through his visibly closed windows. (00:08:00 - 00:09:00)
Deliberate mistake: Am I REALLY supposed to believe that a helicopter is capable of hovering above the top of Mt Everest? [In the DVD specials, the filmmakers say that they're absolutely aware that it's not possible for a helicopter to hover above Mt Everest. They just thought it would be a funny scene if a helicopter pulled the dead guy away from the mountain.] (00:02:15)
Deliberate mistake: When Alexander is travelling to the future for the first time, it shows a speedy acceleration of the events around him. However, the planes that are seen flying by are moving at normal speeds, or at least speeds way too slow since they should be moving too fast to even see, since skyscrapers are being built in a matter of seconds.
Deliberate mistake: When Bond is fighting Zhao in the clinic, they accidentally set off the tomograph Zhao was lying in. As this machine's powerful magnetic fields indeed would pull any metallic object in, no doctor with common sense would allow sharp objects and other stuff within range. You aren't even allowed to carry watches and have to report any dental fillings. (00:43:50)
Deliberate mistake: When Chosen One is dancing in front of Betty, take a look at Betty's face. There is a moment in which the face of the double playing Betty is visible.
Deliberate mistake: At the end when Ali smokes the huge spliff, look in the difference in length between when he first lights it and starts smoking it and when he starts blowing the smoke out. It's about 10 times smaller in the second shot.
Deliberate mistake: When Rachel researches Anna Morgan in the Seattle PI newspaper archives she looks through hardback books. The PI has not only been using microfilm and computer archives for years but archives are available on line at www.seattlepi.com.
Deliberate mistake: As the sub rises backwards to the surface, the stern emerges from the water at a steep angle, then rises near-vertically so that the boat is virtually standing on the tip of its bow. Anything left loose on a countertop would surely fall off. But when the boat falls onto its belly, a close-up shows a pistol sliding off a sink counter into the hand of the Captain- because it's dramatic and cool looking, yet extremely improbable- especially considering that an open tin of shaving foam, its lid and a foam brush all lay on the same counter, undisturbed. (01:27:30)
Deliberate mistake: The sex scene between Paul and Marcy is broken up with a shot of Karen dying alone in the toolshed. The shot is well-lit, but we saw Marcy closing the door when she put Karen back in the shed, leaving the shed virtually pitch dark. So where is the light coming from? (01:02:35)
Deliberate mistake: When Okwe pulls the heart out of the blocked toilet, the water doesn't go out of the toilet. (00:07:50)
Deliberate mistake: Although the first account of what happened in Zhao isn't completely true, the arrows penetrating the calligraphy school are sometimes flying at angles that make their trajectory impossible, such as arrows flying perpendicular to the ground or even flying upward.
Deliberate mistake: When the lady is supposedly in the water with the crocodile, you can see that it isn't her. It is actually Steve in a fat suit and wig.
Deliberate mistake: There is blood all over the back of the couch that's supposed to be from the neck cutting, however there is not a trace of blood on May's dress or anywhere else but her hands. (01:13:30)
Deliberate mistake: In countless shots showing Japanese, and some shots showing Americans, being shot, take notice of the ground that they stand on. Almost every time a bullet(s) will hit below them at their feet, yet they still fall dead. In some shots even, there is a continuous line of shots from a single shooter, hitting the ground, yet numerous Japanese soldiers fall dead.
Deliberate mistake: During the last assault against the hill, a duo of helicopters is mowing down the Vietnamese soldiers with miniguns. In one shot, you can see one chopper coming up behind a tree, all guns blazing. However, the tree, which is in the way of the helicopters right side minigun, remains totally untouched, although, looking at the carnage the guns do to the Vietnamese soldiers, it should have been reduced to toothpicks. (01:51:00)
Deliberate mistake: When Scrat's coconut falls from the tree, it has already had its husk removed. The directors confirm this on the DVD commentary. They may have been worried that a lot of their audience would not recognise a coconut with its husk on. (01:11:45)
