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.

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.

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.
