Continuity mistake: When Amy says that she lost her earring, she's wearing shades. The shot cuts to Stacy and then back to Amy, who is now wearing spectacles without having had enough time to change her glasses off screen. (00:03:40)
Continuity mistake: In the scene where Stacy is lowered into the temple to check on Mathias, the first time we see the crank there are about five loops of rope left on the wheel. After a quick shot of Stacy, the camera goes back to the crank and there are now about twelve loops of rope on the wheel, even though she is being lowered not raised.
