Visible crew/equipment: As Will and Jack duel up top in Brown's shop, in two close-up shots a large plank is visible at their feet with two long black marks along each side detailing where the beams are supposed to be, so that Orlando Bloom and Johnny Depp know where to land as they supposedly leap from beam to beam and feign keeping their balance. (This is ONLY visible on the video version.)
Deliberate mistake: On the fields of Pelennor, after the great battle, before Pippin and Merry meet again, Pippin's Lorien brooch points to his right. As Pippin is walking and looking around, his brooch is pointing to his left. When Pippin is next to Merry, the leaf is pointing to his right again. Obviously the second shot is flipped. (02:16:30)
Revealing mistake: When Karen rips open the wrapping on her gift from Harry, in the close-up of the CD as she holds it with her right hand, it is blatantly obvious that it is not Emma Thompson's hand. Just compare it with the earlier shot of her hand when she sneaks a peak at the card signed - "Sorry I'm such a grumpy bugger.. Bad Harry." (01:27:45)
Continuity mistake: When Tapia is giving the mural artist a dressing-down, his daughter has a book in one hand for most of the scene, but when the shot changes to one from above Tapia and his daughter, the book changes to the other hand. (02:03:15)
Revealing mistake: When Suki and Tej are being booked for speeding when they took Brian's and Roman's cars, the police officer next to them should be writing on his notepad, but instead the words are already written and he is just moving the pen over these words. (01:24:25)
Continuity mistake: In the scene where Bruce is confronting the gang that beat him up earlier, he has the monkey come out of the guy, who falls to the ground in pain. After the other guys run away, there is a shot of Bruce taunting them, but the injured guy is not on the ground behind him, even though he should be visible. A second later, he reappears when Bruce turns to face him. (00:38:35)
Continuity mistake: During their sightseeing in Italy, Sarah and Tom pose for an artist who sketches the two of them. In the first shot, their portrait is tacked on the left of the easel with two other portraits. In the next close-up, their portrait is tacked on the right of the easel. (00:55:30)
Continuity mistake: When John says, "You offend reason sir," Peter floats up. The large light fixture is hanging from the ceiling. However, in the next shot facing Peter when he says, "Just think happy thoughts," where is the light fixture? It's gone so Peter can fly around the ceiling, but it's back again in later shots. (00:21:15)
Deliberate mistake: Almost trivia, but not quite. When Mystique's looking through the guard files to find a suitable candidate, lots of photos flash up very quickly before she finds the guy she uses. Of note is that Bryan Singer pops up in guard uniform (with his own name), and so does someone called "Donner, L". This is most likely referring to Lauren Shuler Donner, one of the producers, and sex is specified as "F", but the photo is of a stubble-coated man. (00:23:10)
Deliberate mistake: When Morpheus is facing the twins' car, the road's not all that wide, and there are concrete barriers both sides of him. After he rolls to the side and slices their car, we see a side shot, quite far back from the road, and the barrier closest to the camera has disappeared (presumably so we get a better view). In a closer view, both barriers are back again. (01:29:25)
Continuity mistake: In the scene where the three Confederate soldiers are about to be executed for desertion, a blindfold is placed around the deserter on the right. It is a narrow strip of cloth covering his eyes. The camera pans to the firing squad and then back to the three men. The blindfold on the deserter on the right, is now much wider.
Continuity mistake: When Natalie Imbruglia and Rowan Atkinson are trying to enter John Malkovich's "chateau", when Natalie is climbing a ladder a tattoo is visible on her lower back. Later, when Pascal Sauvage (Malkovich) is being crowned, Natalie is seen fighting a sniper on the upper-level of the church. When the sniper pushes her away, the tattoo on her lower back is gone.
Continuity mistake: NBA Finals-Game 1. Andie wants Ben to buy her a Coke. During this scene, the camera cuts back and forth between Andie and Ben, and the basketball game. When Ben first looks at the game clock there is a little over a minute left in the game. He rushes to get her soda, and when he gets back, she says she wanted Diet Coke. There is a shot in this sequence where the camera is filming the basketball action, and you can see the game clock with over 7 minutes remaining, even though they are supposed to be nearing the 30 second mark.
