Continuity mistake: At the beginning, the undercover cop says the combination is 666. But the lock has a 4 digit combination.
Continuity mistake: In the scene near the beginning when Johnny Blaze falls from his bike and raises to look at Mephistopheles, when he lowers his cane to the ground it lands to the right of his foot yet when it flips to a frontal shot the cane is in the centre of his body with no time to move the cane.
Continuity mistake: When Helmut is beating up Rio, Rio tries to outrun him and slips on some mud. As Helmut grabs Rio the mud is gone and they are standing on dry sand.
Continuity mistake: The writing on Ghost's sword early in the film has the Turisas rune (representing TH in Thunder) near the hilt, but later not only is a different font used but now the Dagalas rune (representing the D in sword) is at the hilt.
Continuity mistake: During the love scene between Smith and Donna, when the killers first come in the door, Smith's pants keep changing from being down (while he is having sex with Donna) to up around his waist like normal as he rolls off of the bed.
Continuity mistake: When Robert Graysmith is speaking with Sherwood in Sherwood's garden, Robert has his arms crossed. The watch on Robert's left hand changes multiple times between shots. (01:58:25 - 01:59:05)
Continuity mistake: The shape and width of the scar on Stuntman Mike's face slightly varies between the scenes (from thin in the shot where he is pouring some eye drops into his eyes, to almost invisible during the scene at the parking lot in front of the shop in Lebanon, Tennessee, and wide during the final rush).
Suggested correction: This is untrue. The movie is out of sequence, like the reels were put together wrong in an old Grindhouse Theater. The car also changes when his scar is different if you pay attention. This whole movie also takes place in the wrong order of the double feature according to the storyline. This was NOT a mistake but done on purpose and slides to this in the making of book.
Continuity mistake: Right after Jim has his nightmare while sleeping in the car, he looks around for Grace, who is standing outside the car looking at scenery. When Jim sees her, she has her arms crossed over her chest. The next shot, with Jim walking around the car, she has her arms by her side, and immediately after, the shot with Jim approaching her, she has her arms crossed again. All this took place in about 2 seconds, not enough time to drop her arms and recross them exactly the same way as the first shot. (00:19:35)
Continuity mistake: When Ashley is locked out of her house and decides to stay at Kale with Ronnie, she is wearing a brown skirt, up until a scene when she is at Kale's computer (still stranded/locked out) and she is wearing jeans. Where did she get these if she was locked out of her house? (00:35:30 - 00:39:05)
Continuity mistake: When the robber is killed, he falls back and breaks the glass door with a blind. The first time we see the scene, the position of the blind differs from the repetiton from a different view from the flashback.
Continuity mistake: During the operation, the tape on Clay's eyes changes shape and position, several times. When it is first put on it is square and covers the whole eye; later it is rectangular and only covers the middle part of the eye.
Continuity mistake: When the two men are carrying the Christmas tree on the road, it is a huge tree, but when they carry it through the door into the house, it is significantly smaller.
Continuity mistake: During the van chase sequence, the van door is open for the first few minutes. Then the van makes a sharp right turn and immediately it cuts to the door which is now closed. In the immediately following shot, it's back open yet again.
Continuity mistake: When being shot at by the angry waiter, the right hand door mirror was hit by the rifle shot. A few seconds later a view shows only a very minor hole in the glass, and no damage to the rest of the mirror. Surely a rifle shot would have caused more damage to plastic and chrome trim, almost surely passing right through. (00:30:20)
Continuity mistake: Near the beginning of the film when Abby and Neil sit down at the table drinking wine, the amount of wine in Abby's glass changes from almost full to almost empty between shots.
Continuity mistake: In the beginning scene at Vincent's trailer, Errol is looking through the cupboards as he questions Vincent. He comes across an adult magazine, and flips open to a page. He flips another page or two over, and the exact same picture is shown as the first picture he opened to initially.
Continuity mistake: When Jeremy Pivens interacts with the FBI investigators, after the 'wrong' suspected terrorists are killed, he starts to pick up an AK-47 leaning against the wall and its barrel is pointed 'up'. He is told not to and in the next shot is putting it back, but the barrel is now pointing 'down'. Not to mention the continuity flaw in the distance he appears to have moved in a millisecond.
Continuity mistake: When Ro eats the tub of ice cream, the way it faces and the amount in the tub continues to differ.
Continuity mistake: The left tail light of Sadie's car is broken when she picks up the unfortunate hitchhiker. The light works when she turns left off the road. (00:36:20 - 00:38:35)
Continuity mistake: When Walter is imagining himself killing his wife, the bed sheets change from silver to red momentarily after he wakes up.
