Deliberate mistake: It's a humorous twist that Randy's killing is covered up by some random guys passing by with a ghetto blaster, but there was dead silence when Randy was talking earlier; not being in frame does not block soundwaves. (01:05:15)
Deliberate mistake: Although Kubrick might've done this on purpose to show that the Overlook is unusual, as Jack is walking to the office to meet the manager, there is a left turn ahead, leaning to another hallway. When he goes into the manager's office, there's a window behind his desk that shows trees outside, but it shouldn't be there because that's where the hallway is.
Deliberate mistake: When they are listening to the tape, Cheryl yells out and shuts it off. Scott says he wants to hear the rest of it, but then deliberately fast-forwards it a bit before starting it playing. If he wanted to hear the rest of it, why does he skip part of it? This allowed Cheryl to shut it off as soon as she finished her line/action, but then Scott could fast-forward it past a mark on the visible reel-to-reel tape so it would start immediately on the chanting rather than in the middle of the lecture where Cheryl stopped it.
Deliberate mistake: Several times, you see an exterior shot of Nathan's house, and it is very clear that it is the same shot being used over and over, sometimes reversed.
Deliberate mistake: When Ben is discussing boarding up the windows to Tom, he says he still needs to get a few spots upstairs. Why would he need to board up the upstairs windows when the zombies have no way of reaching them?
Deliberate mistake: While walking bare-footed in the barn looking for RJ, Wayne does not raise his feet very high - that is, until he is about to tramp on the nail that is perpendicular to the floor. If Wayne had kept walking like he had been, he might have bumped into the nail or object holding it up, but not got punctured by the nail. (01:06:40)
Deliberate mistake: After Venom eats the head of one of the Drake's henchmen there is no blood from the wound.
Deliberate mistake: When Margo is in the Superstition exhibit, she thinks she hears/sees something and runs for her life. She gets into the women's bathroom and tries catching her breath before the mirror. Hearing a noise outside of the bathroom, she goes into a stall, locks the door, and stands up on the toilet so her feet don't touch the floor. It was just a little old maid washing her hands outside the stall, and the strange sound Margo heard was the maid using her inhaler. However, how is this little old lady - with asthma, we can assume - supposed to have gotten all the way from deep inside the exhibit to the women's room within seconds, pushing a big heavy cart? Why would she even be in such a hurry? We can assume, however, that perhaps this was a deliberate mistake to show that, after all, maybe Margo wasn't just freaking out over nothing...that perhaps something was in the exhibit with her.
Deliberate mistake: Helena asks Justine over to watch Atonement, but she instead goes on her 'date' with Alexis. When the scene cuts to Helena and Emily watching the film, it's actually The Duchess.
Deliberate mistake: There is a wooden chair upside down on the floor, with legs that angle outward. Jack Cain is able to pick up a party-goer, throw him down from over his head, and spear the party-goer on the right side with two of the chair legs. The chair legs are still angled outward but will break off to the side from the force of the party-goer's back hitting them. (01:07:17)
Deliberate mistake: After trying to get away from the monster, Costello finally unties the boat as Abbott rows away from the burning dock. The next shot of the boat has Abbott slowly rowing the boat, but you can see it's not moving as there's no wake, and when they jump off the boat after the Invisible man speaks, it doesn't rock, meaning the boat was mounted to something to prevent any movement, so they could make the jumps into the water.
Deliberate mistake: The wrecker used in this film is a Western Star Model 4964. The manufacturer emblem (a chrome 5-point star superimposed on a large "W") is normally displayed at the top-center of the truck's radiator. Apparently, the film makers could not bring Western Star on board for an advertising agreement, or Western Star specifically objected to their logo appearing in the movie, because the Western Star emblem on the wrecker's radiator is carefully kept out of frame or otherwise obstructed from view throughout the film. For scenes in which a full frontal shot of the wrecker is unavoidable, the Western Star emblem is very deliberately covered up with dark green tape.
Deliberate mistake: Otis was portrayed as an albino in "House of 1000 Corpses" but in this film he has normal skin pigment.
Deliberate mistake: When the captain jumps towards Scott, the distance between the two rows of seats is three times bigger than the other rows shown, obviously to allow for the fight, but still really weird when you look at it.
Deliberate mistake: The images of Spencer's face in the driver's side mirror are not realistic for someone in the driver's seat. The driver's side mirror is angled outward (perhaps 60° beyond a typical angle), but his face is perfectly reflected. When Spencer starts smoking, the viewer gets a glimpse of a figure behind his car. Spencer senses something and his face is shown backwards in the mirror, as if he were crouching outside a few feet from his car. Spencer does not use the more practical rearview mirror. (00:19:11 - 00:19:47)
Deliberate mistake: The number of clicks (sounds) Christine made on the "text to talk" device did not match the total characters she typed. With few exceptions, there were a lot less clicks/sounds than there should have been based on the amount of letters/words she typed. (00:06:40 - 00:15:30)
Deliberate mistake: The blades on the tiller or harrow (?) were only a few inches apart when Burkett was falling back onto them, but only one blade went through his chest. Burkett's body was wide enough for at least three blades to penetrate. Also, the blade appeared to be exiting in the center of his chest (along the button line of his shirt), but the close-up showed the blade to his right. (00:19:40)
Deliberate mistake: Abraham is sitting to the right of and slightly behind the cross he hammered into the ground, but is about 3' away. When there is a close-up, Abraham is much closer to the cross - the end of the crossbar to the right is directly above his shoulder and his knees appear to be close to the vertical bar. (00:45:15)
Deliberate mistake: After the AN-12 launches from the carrier, you see U.S. Navy near the nose of the craft, and MG on the tail code (MG=McGuire Air Force Base). Also, during the flight shots, the plane transforms between a C-130 and AN-12 multiple times.
Deliberate mistake: When the cannister rockets through the ceiling window, the pieces of glass from the initial impact never fall down. Nor are they on top of the window in the next shot. They just sort-of vanish. Additionally, the cracks don't match from the first shot to the second time we see it. There's suddenly less cracks which is odd because it's a digital effect.
