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.
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.
Continuity mistake: Swagger was shot in the upper right chest and lower right abdomen, making him limp badly. When the teacher stitches him up, there is only the bullet hole in his chest. He also miraculously recovers immediately.
Continuity mistake: At the end of National Treasure 1, Riley has a Ferrari 360 Spider. At the beginning of Book of Secrets, when his car is being towed away, it's a Ferrari F430 Spider. At the end of the movie, he is given back a 360 Spider.
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.
Continuity mistake: When Sam and Mikaela handcuff all the agents, Sam is wearing a black short-sleeved tee shirt atop a blue long-sleeved tee, before putting on the hoodie. We see the dark tee sticking out when he and Mikaela climb onto Prime. Then moments later, Sam is wearing ONLY a long white short-sleeved (we see it has short sleeves when Bumblebee gives him the All Spark later, through a tear in the hoodie sleeve) tee shirt under his hoodie, when he falls from Prime, when he witnesses Bumblebee's capture and thereafter. (Earlier, after he knocks Mikaela off the moped, from that point on there is a very large hole at the back of his blue and black tees, where we see his skin under the jagged material edges, with no white material seen anywhere. We also see no sign of a long white undershirt at any time when Sam's dark tees go up, during his many action shots.)
Continuity mistake: During Sandman's attempted heist of the armored truck, he punches Spider-Man through the side of the truck, and the damage to the armored wall significantly changes in the following shots.
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)
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.
Continuity mistake: When John and Mai are fighting at the power plant, John tosses Mai up against a glass board. Her half pony tail has come undone and her hair is a big mess. You see Mai from the back as she gets up to come after John. Her hair is now neatly combed and back in a half pony tail. But as she begins to fight, her hair is once again undone and messy. (01:06:45)
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)
Continuity mistake: In the railway station where 47 is being followed by the FSB, Interpol and the older agent, you see the older agent running down the ramp to platform 9 after 47. His jacket is flying up in the back, and there is no weapon visible. When he stops running, he reaches behind him into the waistband and produces a handgun with a silencer.
Continuity mistake: During the complete car-bomb chase sequence towards the end of the film, Michael Clayton's car is shown in one shot without its lights on. All the surrounding shots in the scene have both cars with their lights on. This is also a slightly revealing error because it shows that they actually filmed these sequences during the day using neutral density filters. (01:41:15)
Continuity mistake: In the scene where Randy is playing table tennis on the stage at the restaurant, just after he has finished hitting the ball blindfolded and says, "Thank you", you can see a man in the background getting up. The shot then switches to the boy with the man in the background still sitting. The shot then switches back to Randy and the man is getting up again.
Continuity mistake: At the beginning, in the scene where Rayne finds two bodies near a small house, she takes out one of her blades. Firstly, she grabs it in a wrong way (the tonfa-like blades should be held under the arm), but when the camera angle changes she holds it properly.
Continuity mistake: After the Zombies are unleashed in the desert scene, we see Carlos crawling under the truck. At first his semi-automatic gun seems to be completely normal. The gun's slide and chamber are closed as if there are still bullets in the magazine or at least one bullet is chambered. But then the camera focuses on his gun and we see the gun's chamber is open - as if there are no bullets left. The gun didn't fire between shots so it's chamber should have been open in the first place. (00:58:10)
Continuity mistake: At the end, when the church doors open, the door on the right opens all the way in the first shot then begins to slowly close back. It is then wide open in the following shot from the other side.
Continuity mistake: When the guys are being hit by bugs, you see Woody drive past everyone, when he gets hit by the bird you see him passing everyone again.
Continuity mistake: After Evans was shot near the end of the movie, Ben Wade jumped out of the train to look at him. If you look over Wade's shoulder, you will see that Nez (the Apache) had already arrived at his spot, and Campos (the Mexican sharpshooter) threw Wade's gun belt to Charlie Prince. After the movie cut a couple of times, Nez was shown walking up, throwing Wade's gun belt to Campos, who then threw it to Charlie Prince.
