Visible crew/equipment: At Barbara and Phil's house, just as the hooded zombie bites a chunk out of Phil's neck (before Shaun leaps over the car hood) the black mat with two long white marks is visible on the pavement, behind the second zombie (beside the car). It's gone in following shots. (00:46:30)
Continuity mistake: When Lucius is putting aftershave on in front of the mirror, he hears the robot outside and runs to the window, leaving the bottle of aftershave on the desk with the lid off. He returns to open the drawer, and the lid is back on. (01:29:00)
Other mistake: In the scene where they're loading Tom Cruise's first victim into the trunk, as Max lifts at the arms you can see the "dead" guy holding onto Max's forearms. (00:20:55)
Continuity mistake: When Howard's wife is leaving Joel's apartment, the first two shots show her trench coat belt hanging from the bottom of the driver's door. In the third shot the belt is no longer hanging from the door. (01:19:30)
Factual error: Flynn says that the chamber in the Mayan temple is "an exact replica of their great temple of Teotihuacan." But Teotihuacan was not a Mayan city, but rather the hub of a separate civilization (themselves called the Teotihuacan). It was in central Mexico, hundreds of miles from the Mayan area in the Yucatan Peninsula.
Continuity mistake: At the very beginning of the movie Patience is at work. She gets yelled at by the boss, she goes home and can't sleep because the neighbors' music is too loud, then she goes back to work. It's the next day, but Patience, her coworker and her boss are all wearing the same clothes. They even make a point to comment on how awful her outfit is and she's wearing the same awful outfit the next day.
Continuity mistake: While traveling out to the reunion, the navigation voice said "now entering Arizona", while at the same time the navigation screen showed them leaving Arizona and entering New Mexico.
Other mistake: The video quality on the phone would not be as good as the film makes out. In fact, as far as I know, no mobile phone has that quality. The fact that they would then be using the video he filmed off the camcorder as evidence just makes no sense, as you definitely wouldn't be able to see anything on the phone anyway.
Revealing mistake: Just before entering Robertson's office after climbing the stairs, Spooner is behind Sonny with a flashlight. The light shines on Sonny's back and the door, but Sonny does not cast a shadow.
Continuity mistake: As the priest descends down the rope ladder into the church for the first time he is handed a lantern by his friend. In the next shot the camera is looking down and you can see that the friend is holding the lantern. Then the next person goes down the same rope ladder and the friend is not holding the lantern, where did the lantern go?
Continuity mistake: In the scene at the mall around Christmas, Cassandra moves her necklace to the side, under her collar. But with each shot it changes from either in front or under her collar. This happens again at the end before Cassandra, Roland, Patrick and Mary go to prom.
Revealing mistake: In the beginning, there is a scene where Sen. Shaw is watching Raymond make a speech on a TV screen. It was obviously put in in post-production because the aide immediately next to the screen is nodding and clapping in agreement at inappropiate times.
Continuity mistake: When Jesse and Celine are walking along, there is a man in a red shirt who is just getting ready to pass them (with the camera shot looking from their backs). The scene shifts to a frontal shot, but the man in the red shirt does not pass immediately as he should have. There is too long of a time gap before he finally appears in the shot and passes Jesse and Celine.
Continuity mistake: When Ana hands over the file to Cora, Cora grabs the file on the side. When it cuts she grabs it on the top of the file. (00:01:20)
Revealing mistake: When Thunderbird 3 lands in London, the jets do not burn the grass they land on.
Continuity mistake: In the very last scene just after Max Lomax exits, the band starts playing again. You can hear drums playing however Roxy is dancing with her boyfriend and there's no-one at the drum kit.
Continuity mistake: In the scene where Katey and James are in his car after leaving La Rosa Negra, James locks the car door on the passenger side but after he makes a move at her, Katey opens the door without unlocking it.
Other mistake: When Alice asks Dan to make her some tea (after he tells her about him and Anna), he walks into the kitchen for just a moment, and comes back to find her gone. He also doesn't see her as he runs downstairs and looks outside. She couldn't have quietly gone down the stairs and out of the building in the short moment that Dan was in the kitchen. If she had moved quickly, there should have been a lot noise from her footsteps.
Continuity mistake: When Mia takes the chicken out of the basket and it gets loose, we see the chicken run away, followed by Mia running after the chicken, and finally the palace guard falling amid a number of boxed, gift-wrapped presents. The only boxed presents that were visible in any of the previous shots were already on the floor, and there were none anywhere close to the palace guard that he could have knocked down as he fell.
Other mistake: When Timon meets Rafiki for the first time, Rafiki is hanging upside down, yet his beard is not affected by gravity and remains pointed upwards.
