Visible crew/equipment: When Monica is in bed with her boyfriend and they get up to dance, the whole film crew is mirrored on the glass of the window.
Continuity mistake: When John is driving to work and he hears Anna on the radio, he swerves to avoid a car. From inside the car you can see that there are no cars in the rear window, yet when the shot changes to an outside shot, there are 3 cars. (00:33:35)
Continuity mistake: In the scene where Watson and Adler are laying out the map, they place two objects on the map to hold it down. In the very next clip where it shows Holmes talking, you see Watson and Adler placing those same objects on the map.
Continuity mistake: When Don Knotts is in the old Simmons mansion, he falls down a chute of some kind. If you watch closely you will see the stunt person looks nothing like Don Knotts. It is a younger man with very straight hair.
Visible crew/equipment: In the scene after Patrick Bateman's second encounter with the detective in his office, we see Bateman having sex at Courtney's apartment. After he rolls off her, Bateman approaches the large, stand-up mirror in the bedroom. In the upper right hand corner of the mirror, a boom microphone can clearly be seen moving around to pick up Christian Bale's lines. The next time we get the same long shot, the microphone is gone. (00:52:45)
Continuity mistake: At the end, the paramedics are taking Samuel L. Jackson into an ambulance. His head is toward the front of the ambulance but in the next shot, Jackson's head is at the back of the ambulance. (02:08:25)
Continuity mistake: When Scott gets his throat cut, blood pours out. Yet when Terri spins him around, there's no blood anywhere on him except a small amount on his shirt sleeves.
Factual error: When Holland March is swimming behind the bar with mermaids, "Get Down On It" from Kool and The gang is playing. That song did not come out until 1981 and the film is set in 1977. (00:39:50)
Continuity mistake: Right at the beginning, a little girl does a somersault and her hat falls off. In the next shot as she's running, she has her hat back on.
Continuity mistake: In the scene where Stanley and Zero are digging to find the chest toward the end of the movie, the background behind them is just a dirt wall. In a following shot upon discovering the box, there are stairs that lead to the hole. In the next shot, these stairs are gone again and it's just the hole again. (01:38:05)
Other mistake: When Sugimura is looking for Kotohiki, he activates his scanner to see if she is nearby. The scanner shows her location, but fails to show either Mitsuko or Kiriyama, who show up quickly after.
Character mistake: During the dancing girl scene, as they are singing the praises of Kane, the girl to the immediate right sings out of time with the rest of the dancers during the line "His favorite son." Even though she forgets to sing the line, she can be heard singing it a bit too late. (00:41:00)
Audio problem: On the first level of the video game, after Velma brings up what she remembers what Eric said about the Scooby snacks in the game, you hear Daphne talking but you see Velma's lips moving. (00:01:00)
Continuity mistake: Saw VII takes place straight after Saw VI. In Saw VI we see Jill put Hoffman in the bear trap and leave. We then see that Hoffman spends around 45 seconds trying to get the trap off before putting in the bars on the window. In this film however, just after Jill closes the door we see the glass break. No delay. (00:08:20)
Other mistake: In the end credits, the filmmakers misspell the name of the town they wish to thank. They spell it "Coupville", but it's actually spelled "Coupeville."
Continuity mistake: After the bird of prey first fires on Enterprise, Kirk is thrown right out of his chair to his left and lands on the floor. The camera pans around the bridge briefly, seeing the rest of the crew staggering and holding onto things. In the very next shot Kirk is back in his chair shouting "back off, back off" and the crew back in their positions as if nothing has happened.
Other mistake: When the slaves are getting into the Portuguese ship (the "Tecora"), the crew shouts in clear Spanish (some Spaniard and some Mexican accent) rather than the expected Portuguese. (01:18:10)
Continuity mistake: In the scene just after Joe finds his parents, when they are sitting in their trailer talking, his parents have a stuffed clown between them. Just before Joe asks them if there ever was a time when they'd be staring at the moon, the clown is slumped forward with its face not visible. In the next shot, when his mom starts her sales pitch about having clowns for sale, the clown is now standing upright between them.
Other mistake: When Chester is taking Jacko's pipe, Nelson gets up out of his seat. When they show Jacko really really mad, you can look in the background and Nelson is sitting down. When they show him again he is out of his seat.
