Continuity mistake: There are a couple of instances in the movie where the models do not correspond with the actual sets. When Klytus arrives at the Hawkmen city he lands near the top of the city. Yet in that very hall there is a pit with a deep void underneath. Such a room could only exist at the bottom of the city. Also, when the Hawkmen start to land on Ajax, its engine section appears to be missing. (01:10:10 - 01:14:30)
Revealing mistake: When Santos catches fire and falls over on deck, the fireproof vest is very visible on his right arm. (00:46:05)
Revealing mistake: During the bedroom scene with Felicity and Fat Bastard you can clearly see the air hose that fills his suit when he rolls over in the bed. (00:49:10)
Revealing mistake: In the scene where they're tumbling down the hill, Buttercup has a beard.
Continuity mistake: When Anakin attaches 3PO's right eye, one shot has the eye in his left hand, then the angle changes and the eye is being applied with the right hand. (00:37:20)
Continuity mistake: When Anakin is in the medical centre lying on his back being transformed into Darth Vader, you can see the main part of the mask being lowered into place but Anakin is not wearing the neck section of the mask that it connects to. We then see the main part lowering directly downwards, in the next shot the neck section is in place. (02:01:20)
Visible crew/equipment: Watch for the boom when the cigar girl's Volvo boat swipes the building. It's on the top left of the screen on the widescreen version.
Visible crew/equipment: Bond follows the girl through the streets of Venice. The camera follows him with a track shot. Bond turns left, going into some kind of alley, and the dolly keeps going. The dolly, camera, and crew are reflected in a window for a second. (02:02:10)
Revealing mistake: When Mandy falls inside the Porsche, her stunt double is noticeable because she is way older than her.
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)
Continuity mistake: When Tom Hanks cuts his hand and loses his temper, he picks up the volleyball with a bloody hand and throws it. When he picks it up, you can see that his fingers are spread. When you see the handprint that he makes "Wilson" with, you can see that the fingerprints are together and parallel.
Continuity mistake: When they first get to the island and they are playing cricket, Keety is telling them all the rules of the game and asks "who doesn't understand?" Richard and Etiene raise their hands - when the angle changes, Richard's other hand is raised.
Revealing mistake: When Fred rushes in to fight the Black Knight Ghost in Mr. Wickles' castle, he is hit in the face several times with the back of his shield. As he falls, you can see the pad on the back of the shield to protect his face. (It is not noticeable when he first runs in.) (00:23:20)
Revealing mistake: Whilst in Q's workshop, Bond places his envelope on Q's X-Ray Document scanner. If you pay close attention to the screen (it's easy to notice anyway) his flight ticket has got VOID written on it 4 times... (00:51:54)
Continuity mistake: The guard sitting on the back of the train has sweat covering the front of his shirt. In the next shot, the sweat is gone.
Visible crew/equipment: During Bud and Coffey's fight in the lab, we see a lightbulb swinging from side to side between the two men. If you look closely, you can see a hand (belonging to a third person) pushing the lightbulb. The only people in the room are Bud and Coffey. (01:44:16)
Revealing mistake: When Jason climbs onto the rail of the fire escape, it is not attached to the wall - intentionally, it has not broken - but then in another shot, two seconds later, it 'breaks'. It pulls out of a visible hole in the wall, although it was never actually attached and there was no hole before. (00:23:25)
Continuity mistake: When the Angels are walking through the sprinklers after getting shot, you can see the bullet holes in each one of the Angels' shirts. When they get to the car, and it blows up, Cameron Diaz's bullet hole disappears. (01:20:00 - 01:21:30)
Visible crew/equipment: When Duane hits the second cow while hanging from the rope, if you watch carefully you can see the head of someone, bent down behind the cow, wearing a white hat. (01:01:30)
Revealing mistake: In the subway scene, when Neo gets slammed towards the wall (and crashes into it) it's visibly Keanu's stunt double.
