Revealing mistake: In the shot when the captain supposedly beheads the nun, her head flies off, but as the body falls forward, you can see the hood of the mantle that was covering the head is intact. (00:02:25)
Revealing mistake: When the captain shoots the man that flees the scene in panic, there's no sign of a wound, burn mark, or tear on the victim. (00:03:20)
Continuity mistake: Nigel accidentally (unconvincingly so) steps on the Beautiful Nun 's bathrobe in a close-up. His toothbrush hand is down his hip, in frame, but when they both gasp in a reaction shot, the toothbrush is between them. (00:17:30)
Continuity mistake: Nigel wonders why prisoners write on walls. He moves the flashlight from the left hand to his right. When he walks back and the shot changes though, instantly it is back in his left. (00:22:10)
Continuity mistake: When Sydney Fox retrieves the parchment with the map, she holds it differently (probably turned 180°) between the close-up and the reverse shots. It also should be noted that the world-class archaeologist just casually dumps on the floor like a piece of garbage a ornate XVI century flask. (00:23:50)
Continuity mistake: When Sydney talks her inexperienced assistance into a reckless climb, Nigel is leaning against he truck in the close-up, when he was not in the rest of the chat. (00:30:25)
Visible crew/equipment: When Sydney taps the shoulder of the baddie who nearly disarmed Nigel, a strong light is cast on his face just before the cut. Nobody was supposed to point a flashlight or a torch at the fight. (00:38:15)
