Continuity mistake: When John is in the Precog chamber, and Agatha grabs him, he is on the small platform, but when Wally comes in, he is no longer on the small platform. (00:27:15 - 00:28:05)
Continuity mistake: At the beginning of the film when Howard Marks goes out for the paper, he walks down his steps outside and reaches the bottom, twice. (00:04:10)
Continuity mistake: When John and the other precrime agents go to arrest Howard Marks, they stand in a group trying to figure out which house is the right one. A couple of shots later there's a wide shot of John from behind with nobody else there, and a couple of shots later still, the agents are all in a group again. (00:11:00)
Continuity mistake: When John runs into the alley he runs past a slightly burnt out car, but in the following shots the car is on the opposite side of the alley. (00:45:55)
Continuity mistake: When Anderton is finally caught at Lara's place, we see a shot (from behind Anderton) of the precop resting the top of the halo on the back of Anderton's head. In the next shot, the halo is rested onto his head again. (02:02:00)
Continuity mistake: In the scene when Anderton escapes out of the Maglev Car, we see him jump into a room full of gymnasts. He is on the floor with his legs up in the air, then we see him lower his legs. Yet, in the next shot his legs are back in the air again and we see his legs go down again. (00:43:10)
Continuity mistake: At the beginning of the film when Anderton and Danny Witwer first meet, in one shot Danny Witwer is standing about six foot away, in the following shot he is really close to Anderton. (00:06:50)
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.
Continuity mistake: At the beginning of the film, when Anderton and the crew go up on the rising platform, you can see a guy approach the platform, and in the following shot he is approaching the platform again. (00:09:15)
Continuity mistake: At the beginning of the movie the date is stated as 2054. However, when Anderton has been identified on the metro and data appears on a clear screen, the date he went missing is listed as December 12, 2055. (00:45:10)
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: When John and Agatha are in Leo Crow's room, John finds the single photo of Sean and as he looks at it we see the back of the photo and the outline of the boy's image. John then finds the multiple photo-strip of Sean with Leo and holds it in front of him, but as he says, "I am going to kill this man," John is actually holding the single photo - note the outline of only Sean's image on the back of the photo. Next shot he's holding the multiple photo-strip again. (01:42:45)
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.
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 John Anderton is fighting off the agents in the car factory, he does a backflip, and then jumps for the approaching walkway, but if you look closely at the floor, the agents feet are visible, therefore signifying they arrived a little early, and stopped. (00:50:40)
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.
