Continuity mistake: When Rick is trapped in the bathroom, he finds John underwater in a bathtub full of suds. As John climbs out of the tub, his body naturally is covered in suds. However, when he and Rick jump out the window and start running away, John's body is completely suds-free. (00:30:15)
Continuity mistake: In the beginning when Brendan Fraser is looking around the tunnels he turns around to see his kid and they scream. As they are screaming they are at eye level but when a few seconds later when they are standing the kid is like 2 feet shorter then Brendan Fraser, and if you look around there is nothing for the kid to have stood on. (00:05:55)
Revealing mistake: In the visions of Nefertiri scene where Nefertiri is fighting Anck-su-Namun back in ancient Egypt, Evie (Nefertiri) gets knocked to the floor and when she lifts her mask up you can see on her right index finger is a band aid/plaster. Did they have plasters back in ancient times? (01:07:49)
Revealing mistake: In the British Museum after O'Connell frees Evie from being sacrificed, they both shoot at glass containers filled with alcohol and formaldehyde. Right before they explode, you can see protective masks very clearly on the guards that were standing in front of them. (00:39:51)
Continuity mistake: During the first battle, the Scorpion King is fighting with his sword in his right hand and his shield in the left. For one instant, they change arms. I assume the film must have been reversed. (00:01:46)
Revealing mistake: In the scene when Rick and John are pinned down in the lavatory by machine gun fire, if you look at the stained glass window before they jump through it, it is smooth but just before they jump through it it is textured like break-away glass. (00:31:40)
Revealing mistake: After Rick and Evie find the bracelet the water starts coming after them. There are then shots of the water and then them running. Finally, they stop and hold each other. Shortly after that the wave comes over them. If you notice right before it hits them, it is their doubles you see. Not the actors. (00:14:55)
Visible crew/equipment: When Ardeth, Rick and Evie arrive at the first city where Imhotep took their son, Evie is walking through the hall where she had the vision of fighting with Anuk-Sun-Amun in her previous life. As she's walking past/behind a column, you can see someone's head and shoulder poking out from the back side of the column. (01:14:57)
Continuity mistake: When Rick jumps over the fire to save Evie in the museum, her arms are tied together. The instant he hits the board and the camera is at another angle, her arms are free. Then when she falls over his shoulder, they are bound again. (00:38:50)
Revealing mistake: In the scene where Rick and Evie break through the wall together with the water (after their son made the columns fall), you can see that Evie is lying on a skateboard on which she's being pulled forward. (It's a black one, visible when she leans over to Rick.) You can also easily see it under Rick. (00:16:10)
Continuity mistake: In the scene where Rick and Eve are hanging from the bars in the flooding tunnel she has her green top on. The water hits them and then they are haning from the bars, but the green top is gone. Then, when the wall breaks and the two of them spill out, she has her green shirt again. (00:16:15)
Continuity mistake: When Patricia Velasquez has her first flashback to her past life, she is in a room with Imhotep. If you look closely at her shoulders in an up close shot, her hair is in front of both of them. Then we cut to a shot of the room from outside (we can see the room through the balcony) and the hair is still over both shoulders. Then we cut to another up close shot of Patricia, and we see that her hair is over her left shoulder, but behind her right one. (00:49:15)
Continuity mistake: When Imhotep is talking to Alex on the train, he turns over an hourglass onto the table. When Imhotep grabs it, he turns his wrist as he turns it over. The next shot is of Imhotep with his hand on the hourglass, only now his hand is right side up. (00:53:20)
Continuity mistake: When Alex is taken on the train, Anuk-su-Namun puts her hand under his chin and kisses him, but when the camera angle changes, her hand isn't under his chin. (00:49:00)
Continuity mistake: When Imhotep is hanging off the ledge at the end, he yells to his woman to help him. After she leaves, he starts to cry. They show him crying and hanging on with his right forearm on the ledge, then it cuts to a shot of Rick and Evie, then back to Imhotep, but now he is using his left forearm to support himself. Potentially he could have swapped arms, but he doesn't show any sign of having shifted his weight, and it happens really quickly. (01:57:15)
Continuity mistake: When Alex is on the train talking to Imhotep, his brown jacket is first worn, but then it's very snugly (depending on the shot.) This is most noticeable when he tells Imhotep that his dad is going to "kick the mummy's arse". (00:53:50)
Chosen answer: He says, "this just might work" meaning he and Alex trying to bring Evie back using the book of the dead.
