Continuity mistake: In the scene with Paxton being tortured, when the German takes the ball out of Paxton's mouth, when the ball falls to the ground, the straps form a circle. Right before the German slips on the ball when he charges at Paxton with the Chainsaw, the straps are perfectly straight, 180 degrees. (01:04:05 - 01:04:40)
Continuity mistake: When Svetlana is seen falling to the ground after being hit by the car, there is blood on her forehead. When she is shown dead with blood pooling under her, there is no blood or wound on her forehead. (01:21:10)
Continuity mistake: When Kana starts walking towards the train, the clock reads 12:53. As Paxton is leaving on the other train it reads 6:15. (01:25:10 - 01:25:50)
Continuity mistake: At the end when the man has his throat slit, there is a shot showing his hand by his glasses. In the long shot, his hand is further away. (01:26:10)
Continuity mistake: In the end scene in the train station, Paxton is tailing the Dutch businessman to the toilet. As he turns to go down the flight of stairs, there is a girl in a white jacket and blue jeans carrying a white bag and going downstairs behind the Dutchman. As the scene continues two seconds later, further down the stairs from the opposite angle, we see the same girl magically appear walking in the opposite direction going up the stairs. (01:26:55)
Continuity mistake: When Paxton & Kana escape the factory by stealing a car, he checks his rear-view mirror to see the car pursuing him - the road has a dividing dashed white line on it. When the angle changes to see them driving away from the camera, there is no line on the road. Approx. time code 1:20:00.
Continuity mistake: When the main character has his fingers cut off with the chainsaw, you can see that three fingers (pinky, ring and middle) get cut off. But in the next shot when you see his hand, and for the rest of the movie, he is only missing two fingers - his pinky and ring finger.
Continuity mistake: At the end of the movie when the guy's head is in the toilet, blood is spilling out into the water. When the shot changes to an overhead shot of the body, the water has no blood in it.
Continuity mistake: In the scene where Paxton runs over the three Slovakian scammers with his car. Just when he hits them, you can see for a split second that the dark haired girl in the middle smashes on the windshield and "sticks" on it. But in the next shot she can be seen rolling over the car. (Slow-motion is not needed to see this.)
Continuity mistake: When the main character is being threatened by the man with the chainsaw, in one shot the chainsaw is being held near his face at about his mouth-level, but in the next shot, it is suddenly about 4-6 inches higher, right in front of his eyes.
Continuity mistake: During the first scene at the disco, closely watch the two Asian girls. Right at the beginning of the scene, they are off to the right, dancing about a yard apart. Immediately in the next shot, they are standing right beside each other.
Continuity mistake: When Paxton follows the Dutch businessman down the stairs into the station, he passes a girl with jeans, crop top/jacket and carrying a white bag who is beginning to go down the stairs. When the angle switches (looking up the stairs at Paxton coming down) the same girl passes him going up the stairs.
Continuity mistake: Right before the businessman has his throat slashed, this is a smear of blood on his right shoulder. After his throat is slashed, the smear disappears.
Continuity mistake: This is a hard one to spot. The businessman's glasses slightly change position at least once without him moving them when he is being killed. The line of the bathroom tile is near where the right lens holder and lens meet, but after he has been killed, the tile line is now in the middle of the lens.
Continuity mistake: When the German torturer holds the chainsaw to Paxton, we are shown a shot of Paxton's shoes and they already appear to be wet from vomit before he does so.
Continuity mistake: When the German torturer goes to get the chainsaw, he drops the gun on top of a machete that is on the edge of the table. When the table is shown when Paxton is escaping, there is no machete on the table. It also appears that the gun moves closer to the three blades which are in the middle of the table.
Continuity mistake: We see a bloody hole on Josh's face which is obviously not made by the drill. This is in fact because part of the scene was cut where the torturer poked him in the face with a metallic object. Since no versions of that scene exist, it makes no sense for it to be there.
Continuity mistake: The torturer crawls to get the chainsaw and as Paxton goes to shoot him he's sitting up.
Continuity mistake: While they're on the train from Amsterdam after Alex tells them where to go for the women if you look out of the window and watch the countryside you see the same road and tree at least three times.
Answer: Exactly, yes. This interaction tells him that the police are in on the operation, and will not help him.
