Continuity: When the main character has his fingers cut off with the chainsaw, you can see that three fingers (His pinky, ring and middle finger) 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.

Factual error: When Paxton arrives at the station at the end of the movie he is supposed to be in Germany, yet there is a sign on the platform which reads 'Praha'. Also watch out for posters and signs in bad german language like an add which reads 'Neu am DVD' (should be 'Neu auf DVD') and a sign with 'Dieser Bahnhof wird Video - bewacht' ('Dieser Bahnhof wird videoüberwacht') on it.

Factual error: At the beginning of the movie, the main characters are supposedly in Amsterdam, but everyone is speaking German, it's not just the main characters doing this.

Continuity: 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: 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.

Factual error: In the beginning, the Amsterdam redlight district is shown. They have shown windows on which sex scene shadows appear. Actually, all redlight windows in Amsterdam have big red-colored thick curtains which are closed when any customer gets in with the prostitute. There is no way that shadows can appear and visitors can see it from outside. Doors are also closed from inside, so it is not possible to open it as shown in the film.

Continuity: 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.

Revealing: Right after Kana opts for suicide by train, watch the security guard who starts running second from the left. He is having a hard time keeping a straight face and is obviously trying to hold off his laughter.

Audio problem: When the main character is talking to the American businessman near the end of the movie, when the businessman says "I mean did you do it real slow?" you can tell that his mouth does not match the words he is saying.

Factual error: When the girl has her eye cut off, pus begins to pour out, but realistically there is no reason for this to happen, nor would it even happen in real life.

Continuity: 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: 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.

Revealing: When the Dutch Businessman has his fingers cut off by the lead character, you can tell the hand is a prop, as the skin tone does not match his hand in previous shots, and it moves unrealistically.

Revealing: When the lead character has his fingers cut off, you can tell the hand is just a prop, as it is completely motionless during the shot.

Continuity: 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.

Factual error: The amount of blood that comes out of the main characters hand when his fingers are cut off is too much to be realistic at all.
