Corrected entry: When the man torturing the main character is shot in the head, he reacts to being shot about a second after the bullet actually hits him.
Corrected entry: The guys are supposed to go to a hostel "someplace near Bratislava, Slovakia". But as they approach the destination train station, they get off in a town called "Poricany" (see the station sign), which is located in the Czech Republic (different country), about 22 miles east from Prague and about 3 hours north-west from Bratislava.
Corrected entry: When the main character is escaping, he gets slowed down by a parked van. As the driver gets in the van, you can see the van move before you hear the engine starting.
Corrected entry: When Pax is hiding on the cart in the "chop shop" room, watch as the body above him gets thrown onto the table to be chopped up. You can CLEARLY see the dead body breathing.
Corrected entry: At the beginning when the guys are in Amsterdam yelling to open the door to the hostel where they stay in. They are actually yelling in German rather than Dutch while they are in Holland. This happens quite frequently at the beginning of the movie.
