Continuity: There is a scene about 2/3 of the way in the movie where you see Jamal (Martin) standing by the lake and his chain is under his shirt, he looks back into the forest and his chain is hanging out of his shirt, then he goes back to the lake and his chain is under his shirt again.

Continuity: When Jamal is held prisoner, he is in a small cage, barely able to move. In the next scene, however, the cage is twice as large, with plenty of room.

Factual error: There is a scene where we can see several flags hanging on the wall of the castle. These are supposed to be flags in the Middle Ages. However, one of them is the present day banner of the Hungarian Republic (where part of the movie was shot).

Continuity: In the scene where the woman is putting a rag on the head of unconscious Jamal, she notices the medallion around his neck and holds it to look at it. When he suddenly sits up, the medallion is tucked into his shirt.

Other: When Martin Lawrence falls over the railing in attempt to get the mysterious necklace, the camera goes to another shot that pulls away from the moat. You can see the logo on the back of Lawerence's cover-alls swimming away at the corner of the screen, when he's supposed to be under water.
