Continuity mistake: When Bruno and Guy first meet on the train Bruno orders some whiskies and lights a cigarette. He talks with this in the corner of his mouth until the camera angle changes mid-sentence when it disappears without him moving. (00:05:10)
Continuity mistake: In the scene where Guy enters Bruno's house to kill his father, Guy takes out a flashlight to look at Bruno's map. In one shot, you can only see the map, and the light is very small and circular, but in a wider shot of Guy's upper torso, the light covers most all of the map.
Continuity mistake: When Guy and Bruno are having lunch on the train, when the camera is over Guy's shoulder there is no salt visible. One can see both salt and pepper when the camera is over Bruno's shoulder.
