Continuity mistake: 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 mistake: 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 mistake: On the DVD version of the movie there are some deleted scenes - one would have explained two mistakes that occurred towards the end of the movie. Mistake one was that there was a hole in the ground when Jonathan and Rick are at the base of the statue of Horus. You can see the hole clearly when Rick lights the TNT - but without the missing scene there is absolutely no reason for that hole to be there and it just sort of appears.
Continuity mistake: In the scene where Evie & her brother meet Brendan's character for the first time, the guards bring Brendan out with both arms shackled together in front. After he kisses Evie the guards pull him away and one of his hands is suddenly free - he quickly tucks it behind his back as he's dragged off.
Factual error: I counted five canopic jars, one of which has the head of a lion. In ancient Egypt there were only four canopic jars - Hapi, the baboon-headed god representing north, Imseti, the human-headed god representing south, Duamutef, the jackal-headed god representing east and Qebehsenuef, the falcon-headed god representing west. None have lion heads.
Continuity mistake: Ardeth Bay removes the Lewis gun from Winston's plane after it crashes in the desert. If you look at the gun, it has the correct 97 round drum (it's really noticeably thick) with a leather carrying handle on top and no paint marks on it - this is correct for aircraft use. Aside from the fact we never see Ardeth Bay remove any spare magazines for it (which would also have been of the 97 round variety), which would have left the gun with little if any ammunition after shooting at the wall of sand, by the time they all arrive in the treasure room, the magazine suddenly changes to the 47 round variety (thinner than the 97 round magazine), which does not have the leather carrying handle, and has the painted marking on the top of it to enable the magazine to be more easily changed at night.
Factual error: Due to the Earth's rotation, the mirror system used to light the tombs would only provide light for about 4 minutes before needing readjustment (tested by the Mythbusters). This would be fine when there were plenty of priests around to adjust them constantly but the light level never changes even though we see Rick and Evie for several minutes at a time.

Continuity mistake: In the scene where the Americans are running from the mummy in the cave, the American with the glasses falls to the ground and his glasses fall off. You see the glasses fall in front of him and after he says "My glasses" you see that another pair of glasses are being thrown from behind him near his right shoulder.
Visible crew/equipment: In the scene where Brendan Fraser and the Americans are talking in the bar before the water turns to blood, there is a shot of two of the Americans and Fraser. Off to the left, you can see a hand dip in and out of frame. This is the First AD's hand. The director said he was checking his watch.
Continuity mistake: In the scene where Imhotep's sarcophagus is opened: Rick and Jonathan stand the sarcophagus up against the wall, and Evie steps a few paces away and stands in front of it. Then the "lid" falls on the floor, where Evie was standing. Then Evie approaches the juicy corpse of Imhotep from an angle. Next she is seen stood directly in front of him, where the lid should be, yet the lid has mysteriously disappeared.
Continuity mistake: When Evie wakes up and sees the rat on her and freaks out, she rolls over and sees the body of Anck-Su-Namun, and screams. About half a second before the camera cuts, you can see a large crack form in the top-left corner of the table that Anck is lying on. Later on, when you see her again, the crack has disappeared. Obviously, it was unintentional damage done to the set that was later fixed.
Continuity mistake: When the biplane dives from the sandstorm created by the mummy, it shows Evelyn looking towards the plane, with the city of the dead behind her. The plane is seen, from her viewpoint, to be flying away when it crashes. However, after the plane sinks O'Connell and his friends walk in the same direction that the plane was flying, presumably AWAY from the city of the dead but the camera shows them walking towards it.
Continuity mistake: When Imhotep's priests break out of the ground, we see a shot of Ardeth, Jonathan and O'Connell starting to shoot them. It flashes back to the priests and then back to the trio and we only THEN see Jonathan reach over and grab some revolvers from beside O'Connell to start shooting.

Deliberate mistake: When they first enter the tomb, Evie moves a mirror which deflects light onto a load of other mirrors. You can see the beam bounce from mirror to mirror as it goes along the chain. Whilst this looks cool, the speed of light is far too quick for this to actually be noticeable as shown.

Continuity mistake: After the scarab enters his body, Jonathan contorts his arm in pain/reaction giving a view of his palm, through which the scarab entered. But there is no visible wound, blood, or any other sign of entry for the scarab to have gotten in. Also there is no visible blood when Rick stabs Jonathan to get the scarab out.
Continuity mistake: When Rick finds Beni in the office, after Beni says "I am immune", Rick slams him into a pile of boxes, sending stuff flying. Nothing is visible behind Beni's head, just a sheet of paper at neck level. Then after Rick says "immune from what?" we cut to a different angle - boxes are now piled much higher behind Beni, and there's a bit of paper resting on his hat.
Continuity mistake: In the scene when they are driving through town trying to escape the mob, the car crashes, and you can see that its lights are on. When Rick helps Evie out of the car, its lights are off. A few seconds later, you can see in the background that its lights are on again.
Continuity mistake: Whenever a scarab crawls out of its "blue gold" shelling, it leaves the shelling behind. At the end of the film when Jonathan picks one up and the scarab crawls inside of him, he begins to scream and you can see the shell still on his hand yet in the next shot, he throws his hands up yet no shell is thrown away or even seen on the ground.
Revealing mistake: When Imhotep transports Evie, Beni and himself back to Hamunaptra, Evie hears the plane and looks up. Before she states "O'Connell," you can see the letters and numbers on the side of the plane are backwards, like a mirror image - it says "B5538" backwards, which resembles "BE228" (no mirror).
Continuity mistake: When the hero and heroine are kissing, you first see it from behind him looking at her face. From that viewing angle they both turn their heads to the right to kiss each other. Then we see it from behind her and in front of him, but now they are both turning they heads a little to the left.
Deliberate mistake: The shot of Ardeth and his companions watching Rick leave Hamunuptra at the start of the film is reused again when Rick, Evie, Jonathan and the Warden re-enter Hamunuptra, although the reused shot has a blue filter over it. Ardeth even says exactly the same line he says in the original shot, but it is subtitled differently.
Continuity mistake: When Imhotep and his zombies are going after the group in the building where Evie reads to locate the other book, watch the mummy's CG mouth when he is walking in the zombie crowd, raises both hands and shouts something. You can see in that scene the CG decay shift on his face a bit.
Other mistake: Evie explains that if Imotep was resurrected he'd bring with him the ten plagues of Egypt. This is followed by (in no particular order) a plague of Locusts, Flies, Water running to blood, the sun being eclipsed and a plague of boils. At the plague of boils Jonathan says 'last but not least, my favourite plague - boils and sores'. How does he know this is the last plague? Aren't there supposed to be 5 more?
Visible crew/equipment: When O Connell is talking about not getting mummified, Imhotep's sarcophagus comes crashing through the ceiling. On a close up shot immediatly following you can see a red wire wrapped around the box and leading up into the air which means the box was guided down so it would fall straight and flat.
Continuity mistake: As the sun is rising, Hamunaptra is revealed (a literal trick of the light). However, long before the sun is fully up (let alone directly overhead), Dr. Chamberlain is seen holding an umbrella over his head, blotting out the sun which is now shining directly *down* on him.
Other mistake: When Evie is walking around after messing up the library Jonathan scares her by making a mummy sit up. He then climbs out and says that he has something for her and moves the mummy's hand and arm about looking for the key. If you slow the film down when he's moving the arm you can see that it's just a piece of wood with some smaller pieces taped on the end.
Revealing mistake: The first night after O'Connell goes back to Hamunaptra with Evie, the camp is attacked. In one shot, when O'Connell is shooting at the attackers, he fires and then swings the gun to his right and fires again. As he swings the gun around the flare from the gun follows the nozzle as though it were, say, a spark on a birthday cake sparkler, definitely not like the spark on a gun.
Audio problem: When Jonathan and Evelin are about to board the boat after Rick gets on, Jonathan says "Yes, yes, you're right. Filthy, rude and a complete scoundrel, there's nothing to like there at all." Before he finishes his sentence it cuts back to Evelin, and his lips don't move.
Continuity mistake: When Henderson gets killed by Imhotep in his hotel room, the shadow of his corpse being thrown shows it to be thrown quite a distance across the room, yet when Imhotep appears, and then walks off, Henderson's corpse is right by his feet. It was thrown much further than that.
Continuity mistake: When they show Anck Su Namun committing suicide at the beginning, when the Pharaoh's guards show up she whips around to face them and all of her hair goes over her left shoulder. None is left on her right shoulder. However, in the shot from the front, she has half of her hair over each shoulder.
Continuity mistake: You'll notice that they put a lot of emphasis on the sun rising and "showing the way." The sun then rises IN FRONT of them. When the camera gives us a view of the riders on the camels, the shadows from their hats fall directly on their faces, when instead there should be no shadows. When the camera moves to show them all riding towards Humanaptra, their shadows fall a little to the left and behind, like it's high noon or something.
Continuity mistake: When Benny is looking for the black book in the office, he gets caught by O'Connell. When they are standing under the fan, you hear the scream of the Egyptologist. They all look towards the camera but when Benny runs out the window behind them, the Egyptologist is there.
Factual error: When Rick is running from the horsemen at the begining, he stops in front of a pillar and waits to be shot. We see the horses round the corner and rear back in fear and one falls over. We then see Rick again and then cut back to the horses, which have all disappeared. There's no way a horse could get up and run off that fast with a rider.
Continuity mistake: The pharaoh realises that his mistress Anck Su Namun was touched by another man because the body paint on her left shoulder is smudged. However, the way it is messed up differs drastically between when it was being smudged by Imhotep and when the pharaoh points to it.
Factual error: In the scene where the Americans find the chest containing the canopic jars, the egyptologist reads the text from left to right. However, the text actually begins from the middle and goes to both directions: one sentence goes from right to left and the other from left to right (this was very common in Ancient Egypt as hieroglyphs could be written in both directions) So, as he started from the left, the highly trained egyptologist was actually reading the inscription backwards.
Factual error: After the American who wears glasses has had his eyes and tongue taken by Imhotep, he still is able to articulate words pretty well, which, if his tongue was really gone, would be impossible-try talking without moving your tongue sometime, and see how unintelligible you are.
Factual error: When Evelyn fights Anck-su-namun, Jonathan is struggling to read some hieroglyphics from the Book of Amun-Ra. Evelyn tells him that the word he can't remember is "Amenophis." However, "Amenophis" is not Egyptian: it is the Greek equivalent of the Egyptian name "Amenhotep" - "Amun is satisfied." In short, the name "Amenophis" could not have been written in the Book of Amun-Ra (let alone have any magical power over the undead priests) simply because it's not Egyptian.
Continuity mistake: When Imhotep takes Benny as his servant, he holds out some gold items in a very skeletal hand (where he had the gold when he had no pockets is another matter). When O'Connell and friends are leaving Hamanoptera, Imhotep's hand comes out of the sand. You can see that it is either a prop hand, or a crewman's hand in a glove, as it is thicker than it was a few moments before.

Continuity mistake: In the scene where Imhotep's sarcophagus first falls through the ceiling Jonathon is practicing his golf swing a few feet away from Rick and Evie. When the sarcophagus falls exactly where Jonathon has been standing, Jonathon is suddenly 20 feet away without having had a chance to move.
Continuity mistake: In the scene where the group is waiting on Evie to decipher where the black book is, Jonathan runs out to get the car and it's pointing one way. When everyone runs out to get in the car, it's now pointing on the opposite direction. There's no way he could've turned the car around that fast.
