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)
Suggested correction: At first the electrodes are beside Norman's head. While the doctor is fixing him in place, at one point camera focuses on his face. Later when he's stepping back for the PC, the electrodes can actually be seen stuck on his body. You can see them if you have an HD copy. So the camera focusing on his face is indicating that the doctor's doing whatever necessary for the process.
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.
Continuity mistake: When Emily Watson first strokes the tiger on the table her watch says 11:15, on the next stroke her watch says 11:20. Then the doctor hands her the stethoscope and her watch says 12:00.
Continuity mistake: In the final scene where Roxie and Velma are dancing in the concert hall, Roxie is on the right and Velma is on the left. They then turn around, and from behind (same point of view as before) they're suddenly the other way around. (01:44:20)
Continuity mistake: When surrounded by police and a garbage truck, Frank drives his car from the overpass onto the passing transport trailer below, then lands behind a hatchback and in front of two cars - a white compact with a sunroof and a grey hatchback. In one specific shot from atop the trailer, as Frank rolls his window down (before he requests the gun) the only vehicle behind Frank's car is the white compact, which is at the trailer's rear. Note things such as the trailer's safety bars, and the view through the compact's windshield for starters. That grey hatchback is back when the ramp is lowered, for the ensuing crashes. (00:08:20)
Continuity mistake: In the end of the diner scene Jude Law fires after the car with Sullivan and his son. A bullet goes through the rear window but not through the windshield. We see the bullet path go by Tom Hanks' head. Regardless, there's no bullet hole anywhere in the car afterwards.
Suggested correction: There is a bullet hole in the rear view glass.
Continuity mistake: In the restaurant scene where the cigar dispute takes place, Bruce gets his fingers broken on his right hand. Later on in the movie, the two FBI agents encounter Bruce in his yellow Hummer. When he rolls down his window, his bandaged LEFT hand is shown.
Continuity mistake: In the showdown between Austin and Britney, when the view goes to a close up of her machine-gun breasts, she has significant cleavage but when it zooms out she has no cleavage. (00:06:10)
Continuity mistake: After Bill the Butcher stabs and beats Amsterdam's face badly (and brands him with a hot knife) notice how as time passes the wounds heal then reappear in varying degrees of severity. This is particularly true with the branding, which is almost absent by the end.
Continuity mistake: As the plane lands in New York, there is a brief shot of the landing gear where a modern wide jet engine nacelle is visible. In all other shots the correct long skinny 60's style nacelle is seen. (02:00:45)
Continuity mistake: In the scene where Tom Green has the boy hanging from a rope with a chainsaw. When the boy cuts the limb the limb hits the car, and bounces onto the ground. The camera cuts to Tom Green and Jason Lee, and then back to a shot where you can see the car and the limb is back on the trunk.
Continuity mistake: When they bring in the car crash victim (future heart donor), the victim is in perfect condition. No blood, broken bones or anything. Pretty good to have been hit by a truck. (01:32:20)
Continuity mistake: At the end of the film, Claire's husband is shot once in the back. However, when we see him from the front, he has TWO exit wounds.
Continuity mistake: The speech that Moore claims/shows then NRA president Charlton Heston giving in Colorado is actually several speeches edited into one. Note how Heston's clothing changes between cuts during this speech.
Continuity mistake: During "The Li'l Zé story" before Li'l Dice (Dadinho) kills Goose (Marreco), a woman's white purse changes position, from the right side of Li'l Dice to his upper left side, between the shots. (00:40:05)
Continuity mistake: In the beginning of the movie where Monty is looking at his old school photo, look closely at his beard. In the next scene when he's in the classroom talking to 'his old friend' his beard has a completely different shape.
Continuity mistake: In the scene on the ferry, when Williams and Pacino are talking, in the shots showing Williams, Pacino is facing the center of the ferry frequently, while immediately afterward in the shots showing Pacino, he is facing Williams again.
Continuity mistake: When Carmela comes to Pero's place and surprises the gang he greets her trying to act cool, leaning against the wall with his arm up. There's a brief shot of Carmela where we also see a bit of Pero who is not moving at all, then the camera is back on Pero and he raises his arm again. (00:55:15)
Continuity mistake: During the ice show Smoochy gets crowned by the fairy who flies in from above. Right before he sits down at the desk to read the "Smoochy Hits #1" issue of Variety, the crown falls off and rolls away across the ice. When he's sitting at the desk, the crown is back. (01:32:51)
