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: Towards the end of the movie, when Joey Nova is trying to get out of town, he sells his football ring to the drug dealer, but in the final scene he is clearly shown wearing the ring when he points the gun at his father.
Revealing mistake: At the beginning of the scene near the end of the movie with Lucius Malfoy fuming at Dumbledore in his office, Malfoy's hair is fanned back behind his shoulders. The lighting in the room illuminates the back of his neck, where you can see his real, short brown hair. (02:22:05)
Revealing mistake: In the scene when the main character is in the library on the internet, she goes to a couple of websites. When the shot shows the URL up top, it is C:\windows98\mydocuments\etc.html. Instead of actually searching on the web they used a premade html page and accessed it from their computer.
Continuity mistake: When Jason is cutting Marie's hair in the hotel room, his watch is on his left wrist. When he and Marie begin to kiss, in this flipped shot Jason's watch is on his right wrist, his moles have changed sides, and the hand-held showerhead behind them is backwards as well. Next shot his watch is back on his left wrist. The flipped shot has nothing to do with the small bathroom mirror. (01:00:56)
Factual error: After the intruders flood the panic room with propane, Jody Foster's character gets a lighter and ignites the propane causing it to burn along the ceiling. This would be impossible as propane is heavier than air and would sink to the floor rather than rise up to the ceiling. Lighting a flame in that room should have caused anyone in the room and on the floor to be engulfed in flames almost instantly.
Continuity mistake: In the beginning of the movie during the skateboard scene with Shaggy and Scooby riding along the conveyor belt, Scooby grabs a hook and both Shaggy and Scooby jump off of the skateboard. You see the skateboard falling off the conveyor belt, but in the next scene it is on the conveyor belt and being crushed. (00:03:20)

Continuity mistake: When Sy is following Nina and Jake after he put the picture of the husband cheating in with Jake's pictures, the cars pull over to the side of the road. If you watch when they pull over, you see that they pull over next to a down sloping hill that is nicely green with grass and a few sporadic trees. But when they show Sy's car in the rearview mirror, you see that they are now pulled next to a large up sloping hill that is covered in leaves, dirt, and a lot of trees. (00:53:40)
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)
Audio problem: When John rips the phone out of the wall, when it hits the floor it makes a bell sound even though its a cordless phone.

Continuity mistake: Before Alice enters the building, you can see part of her newspaper sticking out of her bag - the area that is visible just contains text. After she enters the building, there is another shot of her from behind, and now the paper is showing part of a picture and the barcode. (00:06:15)
Revealing mistake: When Becky meets Simon in the cube, they hug, then Simon literally stabs Becky in the back. As she falls down to the floor, her black shirt reveals not only some of her chest, but part of a black microphone wire. (01:15:15)

Factual error: After Joe spends sometime underwater in the bus, he goes into the village and pulls a picture of his wife out of his pocket to show the village people. After getting that wet, a picture will not be intact, and it would pretty much be stuck together.
