Continuity: In the scene where Jonathan picks up the scarab, it breaks open and the beetle inside starts to crawl under his skin. We see Brendan Fraser tear Jonathan's shirt and cut the beetle out of him. However, in the very next scene, we see Jonathan walking into the temple, his shirt is intact and there is no blood to be seen.

Continuity: In the scene in the library, when Evie is putting back the books. She leans over to put the book back, but it falls to the ground and she is balancing on the ladder.   When the camera cuts back to show the whole ladder, the book is nowhere to be found on the floor.

Continuity: In the scene where Imhotep's priests first pop up, Jonathan is on Rick's left, and the guy in black is on his right. But in that split-second shot that shows them starting to fire, they are on the opposite sides. [In the director's commentary he does mention this but says it's because they had to cut some scenes out due to time, still a mistake but has a reason.]

Continuity: The city at the beginning of the film where the Pharaoh lives is named as Thebes, and you can see the Sphinx and the pyramids in the background, but these are in Giza, not Luxor, as Thebes is now called.

Factual error: I counted five canopic jars, one of which had the head of a lion. In ancient Egypt there were only four canopic jars, Hapy, Imsety, Duamutef and Quhebensenuef, none of which have lion heads.
