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: 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 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: 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: 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: 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: 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: 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 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.
