Continuity mistake: When the cheated husband says "I forgot my glasses", the lover is on top of the wife, and tries to sneak by bouncing way up and then turning to his left. The jump is cut and the angle changes to a close up of the lover, but this time he is right next to the wife, as if he had just moved aside. No bounce. You'll need to freeze the image to notice it.
Suggested correction: If you have to freeze frame, or use slo-mo, to see a mistake, it's not a valid entry.
Continuity mistake: During the Howard Marks previsions, Anderton notices that the two images of the kid and the man show the kid on different sides. At first, he rotates his hand counter-clockwise (from his point-of-view) to see the image where the kid is on his right, and clockwise to the one where the kid is on the left. The camera cuts away, then cuts back; now the opposite is true (clockwise = kid is on the right, counter-clockwise = kid on left).
Continuity mistake: In the scene where Anderton is in flashback to the day he lost his son at the pool, the same woman (of "ample build") walks past him in a pink-ish bikini at least twice.
Revealing mistake: When Anderton first sees himself killing Leo Crow in the precog vision, pay attention to the shot when he says "no". The reflection of Jad in the Hi Tech screen doesn't match with his movements.
Continuity mistake: During the film we see huge highways far above the ground and skyscrapers so tall they have major roads running down them -- all in Washington, DC. But at the end of the film we see a night-time panorama of Washington, and the only tall structure is the Washington Monument.
Continuity mistake: During the lover-husband scene, when the lover and the wife are staring at the husband holding the knife, they keep changing positions from far away to close to each other depending on the shot.
Visible crew/equipment: When John Anderton shoots Leo Crow, the camera mounted on a crane can be seen reflected on the building's glass in the outside shot just a second before the man defenestrates himself.
Continuity mistake: The front door of Howard Marks house has no windows on the sides and a rectangular transom window above when seen from outside. When seen from inside, however, there are side windows and the transom window is now an elongated half-circle. Also the house is magically huge inside, and not in a way that suggests a conversion of two houses into a single unit.
Continuity mistake: At the start, when John Anderton is going to arrest the man who can't see well without his glasses, he his trying to figure out which house the killer is in. While looking around, his helmet is fastened tightly around his neck, however, as he is racing off to the house he pulls the helmet off in a way which couldn't have been accomplished with the strap still fastened.
Continuity mistake: When Anderton is in the street escaping on the jet pack the shot from above shows him tilted upwards (so his body looks higher off the ground).In the following shot from in front of him he's much closer to the ground and tilted downwards.
Continuity mistake: When the Pre-crime agents break into Laras house to catch John, they barge in and surround him, when you see the man with the head piece it is fully extended at the time but when the go to place it on his head the headpiece is not extended untill the agent activates it.
Continuity mistake: When Witwer looks at the prevision with Agatha in the mirror it's not broken, but during the murder it is. The prevision was not altered until the time of the murder was altered by John's delay, so the killing was not 'a different one' until after that point, yet the borken mirror error occurs before time runs out, making it an inconsistency with prevision.
Continuity mistake: When Agatha suddenly scares and grabs John Anderton in the pool, she says, "Can you see?" with her right hand over his left shoulder, but when the shot changes immediately, Agatha's hand is now under his left armpit.
Continuity mistake: During the hovercrafts scene, Anderton enters a room where a kid is playing sax. The kid runs away and leans on the wall, but from a back shot he is seen close to the door. He keeps moving between the wall, door frame and aisle, in the rest of the front and back shots.
Other mistake: When Witwer is killed, he actually reacts to the impact on his head before the shot is heard. We are standing mere feet from the incident, so no 'speed of sound' delay applies. It's an obvious sound error during editing.
Continuity mistake: During the lover-wife-husband scene, the lamp on the night table keeps moving all the time: sometimes slightly away from the bed, others a bit of its screen touches the head rest, and in some angles half of the lamp's screen is touching the bed.
Continuity mistake: When we first see the numbers on room 1009, they are all even. Just before Anderton rotates the "6" to its correct position, however, the number is slightly raised.
Plot hole: Burgess was supposedly willing to commit murder to avoid losing one precog critical to the precrime effort. Indeed, the precogs are "offline" while Agatha is unavailable. But no system dependent on a key individual can last long or be scalable. At the banquet it is suggested precrime will somehow "go national." For that to happen there would need to be a way to create more precogs, which requires creating brain-damaged children of drug addicts.
Suggested correction: Or, in the mean time since his project's success Burgess has been able to collect the funds and influences to actually breed precogs or some other form of procuring them. In whatever way possible as Burgess is not a moral or ethical man.
Other mistake: At the beginning of the movie, we learn that the precogs "do not see what you intend to do, only what you will do" and that they cannot see suicides. At the end, Burgess intends to kill Anderton but does not go through with it; he commits suicide instead. Given these two facts, the precogs should not have seen Burgess' confrontation with Anderton at the end, and a red ball should not have been created.
Suggested correction: Burgess intention was in fact to kill Anderton, but the knowledge of the precogs predicting his murder attempt, the conflict inside his conscious, and the sound of the arriving helicopters made him change his mind at the last second, just like Anderton did in the apartment. The point is they have a choice, and having knowledge of that, only that, changes the future and makes it different from the visions.
Continuity mistake: When Anderton and Agatha approach room "1009" (which looks like "1006"), there's a stairwell/exit to the right of the door. When Anderton bust open "1006" and goes back for Agatha, there's now a hallway to the right of "1009."
