Continuity mistake: In the ending credits, Ule Matobo is listed as "President", but in the film (and later in season 7 of the TV series), he was always referred to as "Prime Minister".
Continuity mistake: During the conference, when the Professor is talking to Leela, Hermes's shirt buttons are not visible but in the next shot, his buttons are visible. (00:11:55)
Continuity mistake: The first time the Achilles is attacked, Cam's relative does not leave the bridge until after Baal gates in. However the second time when Cam is there, he appears as Baal is gating in.
Suggested correction: And the second time, since Cam is now there, the timeline can/will have changed, so something about Cam's presence may have caused him to come down sooner.
Continuity mistake: Torrential rain falls during the big shoot-out scene at the Ghost Market, but when Park Do-won is up on the rooftops, a 360 degree pan shot shows only light clouds that could never dump such rain.
Continuity mistake: When The Spirit is hit by the severed head in the first fight, you can see that the projectile thrown at him doesn't look like a head at all. However, it changes back when he is hit. (00:10:55)
Continuity mistake: When the Porsche Cayenne is racing through the junk yard, in one shot the right headlamp is broken. In the next, it is fine again and then it's broken once more.
Continuity mistake: The car they pour petrol/gasoline over in the closeup shot is a 2007 Chrysler 300C Hemi with the big square-shaped grille. In the long shot where the car blows up, it is not the same car; the grille has changed shape and is more akin to an old Mercedes.
Suggested correction: The grille hasn't changed shape, it looks different because of the explosion damage.
Continuity mistake: In "The Mummy Returns", we were told that the Scorpion King reigned before the Pyramids of Egypt were built. Yet in this film, where the Scorpion King is not yet a king, Layla talks about going to Egypt to see the Pyramids.
Continuity mistake: In the scene where Daphne is talking to the peasant farmer after leaving the King, Luster casts "Flaming Hand of Fiery Doom". Daphne blinks a few times and has a shocked look on her face, but has no other indications that a person exploded in front of her. In the next shot, Luster comes up and pulls "a piece of peasant" off Daphne's cheek that wasn't there before.
Continuity mistake: During this scene, the female lead, Freya, is being attacked by the Moorwen youngster in order to eat her. When above her, the Moorwen's saliva is dripping onto her face, cut away to the monster, as it hears the main characters coming to her rescue. Cut back to Freya and there is none of the saliva on her face, another cut back to the creature and a final cut back to Freya, her face is now covered in saliva again. (01:27:30)
Continuity mistake: At the end of the film, Nicolas Cage assaults the enemy compound with two Glock 17s. When he exits the compound and shoots at the boss's car, which is pulling away, in one shot he is firing a SIG P226, but in a later shot is using a Glock again. (01:28:55 - 01:29:45)
Continuity mistake: When King is fighting with Lazarus in the bar, Lazarus gets blood near his mouth like you get when getting hit in the face. But when they fight near the white door, the blood is gone. (01:13:00 - 01:18:00)
Continuity mistake: When the soldiers rip off posters that depicts racial images of buffalo soldiers, the board underneath remains blank. Later in the movie, when they are about to escape the town, the board is shown with tattered old postings again.

This black Kia takes a shot that completely shatters the windshield, but seconds later it crashes and the copilot is expelled through an undamaged windshield.
