Continuity mistake: In the beginning, when Anderton arrests the jealous husband, he notes that he is being arrested on April 22 - that day - for the future murder of his wife and her lover. Later, while Anderton is jogging, we see billboards advocating a "Yes" vote on pre-crime on April 22. The next day, Anderton's boss Lamar notes that the vote is in a week, which would make it April 15, making the day that the jealous husband was arrested April 14, not April 22. (00:13:05 - 00:15:15)
Continuity mistake: When Norman is getting ready to test himself, he lies down on the bed, fastens himself in and the doctor goes to the computer. However, when it shows him being brought in to the chamber he has several electrodes connected to his chest and head. (00:15:20)
Continuity mistake: In the latter half of the movie, Picard looks at a picture of himself from his days as a Starfleet Academy cadet while Beverly looks on too. This picture is actually the actor Tom Hardy (Shinzon, Picard's clone) and he appears with a completely bald/shaved head. Showing Picard bald as a cadet completely contradicts the TNG series. In the TNG episode 'Tapestry', a flashback set in 2327 (the year Picard graduated from the Academy), Picard is shown with a full head of hair. Also, in the TNG episode 'Violations', a flashback set in 2354 shows Picard with a partial head of hair when he takes Beverly to see her dead husband Jack's body. (00:46:25)
Deliberate mistake: When MIB agents exit the lift to get into the main hall of the MIB Office, the lift opens halfway up the wall and they need to go down a little platform. But when K and J return during the lockdown and face the trashcan with guns, the lift opens at floor level, so it can be conveniently peppered with bullets. (01:02:05)
Revealing mistake: When Amidala and Anakin are eating and he cuts her a piece of the fruit and "floats" it back to her, the bite appears in the fruit a split second before she actually eats it. [This appears to be fixed in rereleased versions]. (00:53:40)
Factual error: When Philby and Alexander are talking about Albert Einstein, Alexander mentions that Einstein is a patent clerk. The beginning of this movie takes place in the year 1899. Einstein was still in school and didn't become a patent clerk until 1902.
Factual error: When they first pick up the Mona Lisa, they show the back. There you can see a canvas sheet over a wooden framework. However, the Mona Lisa is painted directly onto wood, no canvas at all. The scan they run even says it's painted onto wood, despite visual evidence to the contrary. (00:06:35)
Continuity mistake: During the scene when Mr. Devlin is in De L'Air, the bug store, the eyes of the young black woman with whom he is speaking change back and forth from blue-gray to brown. (00:15:18)
Continuity mistake: Carmen is wearing white sneakers riding with Juni on the magnetic transporter. After jumping off the magnetic rider and entering the hidden temple, Carmen is wearing black sneakers.
Continuity mistake: When the Horsemen team are ready to play the start to skate up to the arena. You see a back view and Jonathan clearly doesn't have his white T-Shirt over his black suit. They cut to someone else then back to the team and Jonathan clearly has his white shirt on.
Continuity mistake: In the scene where the townspeople are fleeing to the mall there is a shot of the Deputy driving the car. You can see the top left hand corner of the windshield is covered in green goo, but when you see them parking the windscreen is completely clean. (01:03:35)
Factual error: In the DJ spin-off scene, Zach and Francessca help make Meeker cool by going into hypertime and giving him a dance lesson. At one point, we see Zach and Francessca in hypertime making Meeker do flips. Then, in real time, we see that Meeker is doing the flips at the same speed that he was doing in hypertime. Wouldn't he be going a lot faster in real time, not the same speed as he was in hypertime?
Continuity mistake: When Graham goes into Ray's kitchen you see the vegetables scattered and the knife further on the other side of them. When Graham leans up for the knife, however, it is on the other side of the now grouped vegetables. (00:56:40 - 00:58:10)
Visible crew/equipment: Watch the scene where Frank gets killed. In the last shot of this scene, we see a soldier standing over the dead body. Keep an eye on the right side of the screen as the camera slowly moves away and you should see one of the cameras and a cameraman on the ground next to a large metal object.
Revealing mistake: When the megalodon attacks the yacht the party goers jump off the yacht, and some of them reach the large round safety raft. To the raft's right, there is a visible yellow line attached to it so it doesn't drift away for the shots.
Factual error: When the archangels jump from the helicopter, the "bait" is looking behind him saying he can see the dragon. For a parajumper to look between his legs to view behind himself, he would de-arch and thus de-stabilise himself while travelling at that speed. It would send the jumper into a barrel-roll spin.
