Continuity: 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.

Revealing: 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.

Revealing: 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.

Continuity: 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.

Continuity: 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.

Revealing: 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.

Continuity: When Ardeth (Oded Fehr) waves goodbye to the Medjai leaders, at Izzy's place from the front his right arm is raised. They show a behind shot and his arm is lowered. They go back to the front and his arm is still raised.

Factual error: 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?

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.

Continuity: 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.
