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.Piemanmoo
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.
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: At the start of the movie, two wooden balls are created to name the next victim and killer. After the balls are created, they are dull and unpolished, but their travel through the tubes shows them to now be highly polished and shiny. (00:01:55)GalahadFairlight
Plot hole: Burgess frames Anderton for Witwer's murder, using Anderton's gun in Anderton's house, but Anderton has an airtight alibi; at the same time as the murder, he was arriving at his ex-wife's home. His ex is even on the phone with Burgess, who asks if that's John arriving with Agatha.Cubs Fan
Visible crew/equipment: When John Anderton is walking around the hotel room before meeting Leo Crow, just before he spots the photos on the bed, he glances over towards the direction of the bed - if you look to the left of him, you can make out a cameraman's face and hand where he is holding a camera in the reflection of the glass window.mhumphris
Continuity mistake: The wooden balls etched with the Perpetrator and Victims show the grain running left-to-right across the names when they are first displayed on the cutting machine. But when Anderton removes the balls and places them on the screen (or drops), the names appear to be written with a pen, and the grain is either non-existent or run top-down across the names. This suggests the balls on display in the cutting machine are nicely generated by a computer and much different to the actual props.
Plot hole: In the scene where Anderton is talking with Hineman, she says to him that "You will bring down the [Precrime] system yourself if you manage to kill your victim. That would be the most spectacular public display of how Precrime didn't work." Shouldn't she be saying "If you manage to not kill your victim"? (01:01:30)Floyd1977
Continuity mistake: When Lara, standing, is putting on Lamar's tie while he is seated, he gives himself away regarding the drowning of Anne Lively. Lara's arms stop moving and we see her standing straight, her arms by her side, and she says that she never said that Anne was drowned. We cut back to Lamar, and Lara still has her arms around Lamar.Allister Cooper, 2011
Continuity mistake: When we see the Leo Crow previsions for the first time, we see the numbers "9" and "6" backwards because we are seeing the previsions from behind the screen. But in the cyberparlor we see the previsions from the same side that Anderton and Riley are watching them, and the numbers are still backward.Matty Blast
