Continuity mistake: When Carter and Lee are fleeing the motorcycle thugs in George's cab, the driver's seatbelt is hanging unused. In the next shot, George is suddenly wearing his seatbelt. (00:34:55)
Continuity mistake: This movie is supposed to take place before the film released with Johnny Knoxville, yet in this film the vehicle is freshly painted and bears the Confederate Flag that wasn't added until halfway through the first film.
Continuity mistake: Mike avoids colliding head-on with a pickup by swerving off the road into a farm field. He does this after passing a tractor and flatbed truck to his right. The shot changes and he is turning off the road into the field between the tractor and truck. (01:36:50)
Continuity mistake: When Ben and Gwen are fighting off aliens on Incarcecon, right after the tetramand destroys the hoverboard, the Omnitrix is missing from Ben's wrist.
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: 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 Eddie is about to be interrogated by the Turks, he's tied up with his hat on. In the next shot his hat is off, and just as the Turk administers the truth shot he rips Eddie's hat of his head.
Continuity mistake: Doomsday has a bone spike protruding up from each of his 4 knuckles. But when Doomsday grabs Superman by the head and draws back to punch him hard in the face, the spike on his thumb is missing. Superman catches his fist, and in that shot you can see two more of the spikes have vanished, and Doomsday only has one over his middle knuckle. (00:23:55)
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: 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 Sarah is on the beach in a gown and slippers, she takes the slippers off, then they are back on, then seen off, on the sand, again.
Continuity mistake: The bike that Tim uses to escape from Brian Cervier's ranch switches from a four stroke to a two stroke in the scene where it runs out of gas.
Continuity mistake: All wide shots of Hrothgar's hall show it in the outer ward of his fortress, about two hundred metres from the towers on the edge of the cliff, with open ground on three sides and an embankment on the fourth. But later several characters are able to step straight out of the hall onto a balcony that overhangs the cliffs and sea below.
Continuity mistake: Shoeshine is telling Jack to 'give the dog your food'. Jack throws him a rubber steak, which moves further away from Shoeshine in a subsequent shot. (00:35:00)
Continuity mistake: When the helicopter plummets into the wedding terrace, its nose is either pointing the right side or the left, depending on the shot. No continuity at all.
