Other mistake: In quite a few shots during the film, it is much too obvious that there are no lenses in Harry's glasses, whereas in previous and following shots the glasses have lenses. A couple of instances are: when Harry drinks the Felix Felicis and when Harry kneels beside Dumbledore, at the foot of the Astronomy Tower.
Other mistake: Poor guy George obviously has his heart on the wrong side - that is at least where his hand goes when he suffers his heart attack.
Other mistake: When the monk arrives with Jackson and the others at the gate leading into the secret entrance of the ships, the countdown to impact timer reads about 28 minutes. It is highly implausible that the group, which contains elderly and small children, are able to get to the top of what looks to be a 100 story staircase in less than 15 minutes without breaking a sweat. Once they are inside the hatch, the countdown to impact timer reads about 13 minutes.
Other mistake: Capt Cahill was declared dead after the helicopter he was in crashed and then taken captive. I spent almost 24 years in the military and know that if a body is not found, even though presumed dead, the official status is Missing in Action (MIA). The notification to Capt Cahill's family should have been MIA not dead.
Other mistake: During the time capsule recovery ceremony, there is a man standing next to Nicolas Cage, who pulls out his cell phone to take a picture of the ceremony. However, he's holding the cell phone wrong, pointing the camera towards himself.
Other mistake: After Langdon saves the last of the Preferati by diving into the fountain, he heads off to St. Angelo with dry clothes. Since it is only ten or fifteen minutes later, his clothes should be soaked.
Other mistake: When Daniel is playing Guitar Hero with his friends, after he and his friends leave the game to go outside, if you look closely at the TV, you can see that the game is still playing (notes are still being strummed) even though there is no one at the controls. (00:23:05)
Other mistake: During the Comedian's funeral, in a shot from above showing both grave and the casket, the grave is actually shorter than the casket. (00:33:55)
Other mistake: When Holmes searches for hidden door after St. Thomas' death he bumps the door and it moves before he knocks on the wall to find out which side seems to be a door.
Other mistake: After killing his inmate, notice the blood on the inmate's neck is present in great amount. After camera changes, the blood is only on the shirt, the neck is clean with no holes nor coagulated blood. (00:51:00 - 00:51:45)
Other mistake: Because of the way it works when making a mold, the engraving on the man's teeth would barely have been captured, yet they showed up sharp and clear when the mold was removed.
Other mistake: During the scene in which Michael and SJ are singing and have a wreck, the "Passenger Airbag OFF" light is on. However, Michael is said to have stopped the airbag that wouldn't have deployed. Nothing is stated to show that it would have been faulty.
Other mistake: In a scene toward the end of the film, there is a shot showing a calendar with the month March 1998. It shows Friday as being the 13th (reference to Philip Morris' birthday), but Saturday appears as the 15th. Did the actual month of March, 1998 not contain the 14th?
Other mistake: In the beginning of the movie, Notorious B.I.G. is a little boy sitting on his porch writing rhymes on his notebook and he is left-handed. Later in the movie, when Notorious B.I.G. is an adult, he is right-handed.
Other mistake: In the scene where Madiba reads in the newspaper about the Springbok coach and manager being fired, the article's heading reads "Springbok coach and manager axed" but the article itself is actually about the South African and England cricket teams.
Other mistake: When the Kelvin is about to impact Nero's ship, the countdown, in seconds, goes from xx.00 to xx.30. Meaning the fraction of the seconds start at .30 when they should start at .99.
Other mistake: The Union flag in the comms room at Amundsen-Scott base is upside down. They did get the one flying outside right, though.
Other mistake: The commentator says that Derby deposed Leeds as League Champion, but Arsenal held the title before Derby did.
Other mistake: As Viggo Mortensen narrates, it's been years since every crop and animal has died. Trees have been dead so long they're rotting where they stand and falling over with a stiff wind or slight tremor. Yet, in the woods, there are always fallen leaves on the ground which ought to have long ago decomposed, rain or no rain. Obviously, they can't sweep out the whole forest to make a movie.
Other mistake: Shortly after the start of the movie, when Eric Bana's character reappears in the library and starts to put his clothes back on, his pants are already undone. If he had suddenly vanished from the library, then his pants should not be undone (unless, of course, he was up to no good just as he vanished).
