Continuity mistake: When Alex, Rick and Evie arrive at the museum, Alex asks his mom if she'd want to stick around and help him open the Emperor's coffin. Pay attention to the strap on Evie's purse. It changes position on her arm repeatedly between shots. For example, in one shot it's right around her wrist next to her hand, but in the next shot, it's suddenly way down her arm next to her elbow. The strap changes position between cuts at least three times throughout the scene.

Continuity mistake: When the evil general is addressing his soldiers near the beginning, pay attention to his second-in-command. (The woman.) Repeatedly throughout the scene, the distance between her and the general seems to change instantly between edits. Sometimes she's practically right next to him, sometimes she's about 5 feet away, etc. She also instantly turns from facing forward at the soldiers to facing sideways at the general between edits at one point near the end of the scene.

Continuity mistake: During the museum scene, when the evil general says "Once this touches him, the emperor will rise!" Watch Rick. In the first shot, he is turning his whole body to look at the general, but when it cuts to the wide shot, suddenly his body is facing away and only his head is turned.

Continuity mistake: During the final battle, when Rick delivers the line "I really hate mummies!" and Evie responds with "Seems the feeling's mutual!" pay attention. In the first shot, Evie is about five feet behind Rick and is facing away from him, but when it cuts, she's suddenly standing right next to him (literally shoulder-to-shoulder), and is facing the same direction as he is.

Continuity mistake: This mistake is somewhat abstract and subtle, so it can be hard to catch. When the Yeti arrive, at a few random points throughout the scene, the "density" of the falling snow changes instantly between cuts. Ex. When Evie helps Lin execute a spin-kick, in one shot there's a ton of snow in the air, but after a quick cut, there's suddenly significantly less snow in the air. It's clear that the fake snow wasn't necessarily being dropped at a 100% consistent rate from take to take during filming.

Continuity mistake: When Mad Dog is introduced, he delivers the line "Now Ricochet, he had his hands all over me girl!" In the first shot, he lifts both hands and points at Rick with both, but when it cuts, he's only pointing at him with his left hand, and then lifts his right hand up a second time.

Continuity mistake: When Yuan fights the Emperor, shortly after the Emperor realises she's mortal, she leaps towards him and twirls through the air. If you look close, her sword swaps hands between cuts when it connects with the Emperor's sword. First it's in her right hand, then her left hand, then it's back in her right hand. It looks like the left-hand shot was an alternate take of the shot right after, and they flipped it horizontally to create a "different camera angle" in editing, hence the hand-swap.

TedStixon

Continuity mistake: When Wilson meets Rick and Evie at the museum, pay attention when Rick delivers the line about giving them a heads up next time Wilson takes Alex on one of "his fieldtrips." In the first shot, Wilson's arms at down at his side. In the next shot, suddenly they are up and he's patting his chest while saying "Yes, of course." The shots are back-to-back, so there's no time for him to have lifted his arms between edits.

TedStixon

Continuity mistake: When Mad Dog is flying the O'Connell's and Lin in the plane, Mad Dog remarks that he can't guarantee they'll live, and it cuts to a close-up of Rick sarcastically saying "Great!" Watch Alex... he goes from facing his left to facing his right between edits.

TedStixon

Continuity mistake: When Lin is explaining what needs to happen at the club, pay attention when she says the lines "Once the diamond is placed at the top, it will point the way to Shangri-La. Yang still has the diamond..." There are a series of cuts throughout these lines, and Lin goes from facing forward towards Alex to facing sideways towards Rick between two of the edits.
