Factual error: During the fight scene with Sandman in the armored car, the Terminal Tower can be seen in the background, which is a landmark in Cleveland, Ohio (where the scene was shot), not in New York City.
Continuity mistake: When Nick is sitting on the bed talking to Jessica, her position changes from lying on her side to lying on her back, as the camera angle changes.
Factual error: When Swagger is fleeing from the police in the car wash after being shot, the radio says that he is at a car wash at 9th and Girard. There is no such intersection. On Girard Ave, 9th street picks up south and north of that street.
Visible crew/equipment: At Hoover Dam, after the salute, when Defense Secretary Keller speaks with Lennox and Epps, the reflection of the white reflector screen is visible on Keller's glasses. What's more, the boom mic's reflection is actually visible within the reflector screen's reflection. Two for the price of one. (01:35:30)
Continuity mistake: On the small sand spit, when Jack, Elizabeth and Barbossa meet with Will, Beckett, and Davy Jones, the leather cuff Jack wears on his right hand actually disappears and reappears twice during the meeting.
Revealing mistake: In the day following the Rider's first ride, Cage shows up at the street that has been burned down the center. A person very close to the beginning of that scene walks on the broken up rocks and it moves as if it were a pad or a sponge. It wasn't a rock moving because the street moves with the rock. It happens a couple of times during that scene.
Factual error: Ben, Abigail and Riley arrive at the Library of Congress to take the President's Book very late at night. However the Library of Congress, despite being shown as open, consistently closes at 5 PM.
Continuity mistake: When Amber and Jonesy get an arrow through the head, the cannibal was on Jonesy's side, so the tip should have gone through Amber's head, not Jonesy's.
Plot hole: Since they took down the telephone network, it would have been impossible for Justin Long to even be speaking to the emergency response woman for the car, much less send a signal to start the car up.
Suggested correction: Is it possible this is a satellite phone call akin to Onstar?
No, the BMW system requires a cell signal to work, which was taken down earlier in the movie.
Revealing mistake: As Carlos is giving his final goodbyes to Claire you can see in the background automobiles driving down the freeway. Shouldn't these roads be empty rather than having what seems to be a thriving highway? (01:10:00)
Suggested correction: Not a single car in the background.
Factual error: In the final standoff, Smith shoots Hertz by holding cartridges between his fingers in the fire. This is not remotely believable. The casings, weighing much less than the bullets, would have been blasted off while the bullets themselves would have gone nowhere. (01:15:15)
Continuity mistake: The birth of the Predalien in this movie is completely different than it was in the first AVP. The lights on the table are different and the Predalien bursts out differently than in the first film. (00:01:30)
Plot hole: The admiral receives the news of the stolen aircraft from the general over an open radio, with umpteen enlisted personnel within earshot. However, when the air group commander asks what the OP is about, the admiral tells him that it is on a need-to-know basis.
Revealing mistake: Underdog's first costume is supposed to be a felted down (the more accurate term would be fulled) wool sweater. When wool is felted the stitches lose clear definition and usually achieve a "felted" look. It is clear that the sweater in the movie has just been switched for another smaller sweater as the stitches are still sharply defined after it has been pulled from the dryer. This is especially clear around the U. No attempt to make the smaller sweater look "felted" was made. This refers to the original costume with the solid white U, not the second costume with the yellow outlined U.
Factual error: If you pay attention to the backgrounds of the scene where Frank is in the airport and when Frank is being arrested as he walks from the church, you can see two cars pass by which weren't produced until at least 2000.
Continuity mistake: Nick's character is eating an ice cream in the police car and eats the whole thing. When the shot changes to Simon's side, he's still got about half of it left.
Continuity mistake: When Bourne is talking to Firsch, the gun he is holding changes from a Glock in the shots facing Bourne, to a SigPro when the shots face Firsch.
Visible crew/equipment: When stuntman Mike and the girls cars come back together after being separated by a pond, the shadow of a car-mounted camera crane is visible in the left bottom corner. (01:44:00)
Continuity mistake: During the fight between Raph and Leo, Raph breaks Leo's swords. Later when Raph gives the broken swords to Splinter they are broken much closer to the hilt then before. (00:56:40 - 01:00:25)
Plot hole: Spoiler! We find out that "Rogue" is actually Tom Lone, who killed the real Rogue and destroyed his face to prevent identification, then had plastic surgery and went underground to get revenge. But how is the body never identified? Lone was a cop, they'd have blood type, DNA etc. on file, which would have proved the body wasn't his.
