Revealing mistake: When Ami's chest is being drilled by the "drill-bra" at the end of the movie, you can see blood flowing from her chest, obviously because of the damage the drills are causing her. Yet, later, you can see absolutely no cuts or marks on her breasts or upper chest, where the drills were penetrating her skin. The skin is simply soaked with blood.
Continuity mistake: During the Deathball Match, the booth window is smashed and Wernstrom gets knocked onto the court, however in the next overview shot, the window is intact and he is still standing behind it. (00:15:10)
Plot hole: In the scene where Ba'al goes through the stargate and arrives in 1939, the event horizon from the stargate puts a hole in the haul of the ship. Later when SG1 goes through the stargate the hole is covered with ice. The event horizon created from SG1 would have been the same as the previous one and removed the ice from the hole.
Continuity mistake: When Toorop gets Aurora to New York, the back windows of the cab they are riding in are clear, normal windows. But when they get to the apartment and get out of the cab, the back windows are suddenly tinted.
Visible crew/equipment: During the chase through the jungle, the hand-held camera operator and stills photographer are visible on the left side of the frame. (01:06:30)
Factual error: When Leonardo DiCaprio is arriving on the tarmac at what is supposed to be Abu Dhabi, the main (and very distinctive) Dulles airport terminal is visible in the background.
Factual error: Although correctly addressed as "captain" towards the end of the film, Richthofen continues to wear the rank insignia of an oberleutnant (lieutenant).
Revealing mistake: While Punisher is killing Pittsy, you can tell he is holding a dummy, not the real girl.
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: In the scary door, the hay stack on the barn it diagonal, but when the aliens are attacking, the hay stack is vertical. (00:13:30)
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: 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.
Visible crew/equipment: When Brother Silence/Cass leaves the house after finishing the campaign at the end of the movie, he opens the front door to leave and there is a glass door/screen there outside the house. For a second you can see a crew member holding the boom mike in the reflection of the glass door. (01:28:10)
Audio problem: At the start of the movie, the soldiers switch on the lights on the vehicles. Each light has a sound effect to a massive spot light activating, when in reality they are just headlights and wouldn't make any kind of sound.
Audio problem: The day after Operation Mardonius, when the first set of bombs explodes you first see the explosion and then hear it after a second, then as the last bombs explode you both see and hear the sound at the same time.
Factual error: When the captain is arguing with the Armed Services Committee chairman, Homeland Security is mentioned. However this movie takes place prior to Desert Shield, and the Department of Homeland Security wasn't created until over a decade later.
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)
Factual error: During the opening credits. An LCD screen is shown with lat/long coordinates. The movie takes place in the Persian Gulf. The coordinates are in the vicinity of Oceanside, CA.
Revealing mistake: The El Camino that is going over the cliff, which has just been shot in the tailgate with a 50 caliber rifle, has no tailgate damage. Also at the same time stamp, when the El Camino is upside down, it is obvious there is no transmission or drive shaft in the car. They even show you this with a close-up. (00:46:20)
