Plot hole: Zi Juan tells the rest of the group when they are in Shangri La that she will take the first watch at the entrance and guard against the emperor getting in. A few shots later, she then decides to have a conversation with her daughter nowhere near the entrance, and now with no-one guarding, means he gets in unchallenged.
Suggested correction: A character briefly leaving their watch to deliver important information as Zi Juan was doing isn't a mistake, and it's definitely not a plot hole, since it in no way contradicts the movie's logic or creates a hole in the narrative. At best, Zi Juan was being a little foolish leaving her watch, but a character being a little foolish isn't a "movie mistake." After all, people make foolish choices all the time in real life. Plus, as demonstrated by the movie, it doesn't really matter anyways - the Emperor's powers are back, so she wouldn't have been able to stop him even if she had kept watch.
Revealing mistake: As the emperor raises his army, you see the holes form into the ground and the armies march. After a close up and the camera pans to get a larger view, watch closely and you can see the army take a totally different formation, caused by a computer generator. (01:19:40)
Suggested correction: The scene is edited using montage-style editing. (Including obvious fades and time-jumps.) It would take far too long to show the scene start-to-finish in real-time. The fact that the formation changes between shots is acceptable within the context of a montage because a montage implies passage of time between edits.
Other mistake: When the avalanche is over and the Yeti are digging out our heroes, they are conveniently less than four feet from the surface of the snow, despite the fact that millions of tons of snow has just landed on them.
Suggested correction: First of all, they're not buried in "less than four feet" of snow. Judging by how far they have to be lifted, they all seem to be about 4-6 feet from the surface. And second, according to the Baker Mountain Guides website (they specialize in mountaineering, rock-climbing and skiing, so they're a good source), this is pretty much 100% accurate. The average burial depth of an avalanche is around 1.3 meters... that's about 4 feet. Sure, you could get buried in more (or less)... but the fact is, the movie is within an objectively, factually accurate range, so this cannot logically be considered a valid mistake.
Trivia: The film made $400m, the lowest in the franchise, and had mediocre reviews.
Suggested correction: Actually, "The Scorpion King" has by far the lowest gross of the '99 "Mummy" franchise. Additionally, I don't see how reviews constitute trivia.
