Continuity mistake: When Nick and Bobby are playing craps in Rusty Nail's barn, Nick rolls "chest," resulting in Rusty branding Bobby with his R key chain. Rusty puts the red hot key chain in Bobby's shirt pocket and holds it against his chest. When Rusty lets go, you can see a hole has been burned into Bobby's shirt. The very next shot, Bobby is rolling the dice and his shirt is intact. Later on at the very end of the film, Bobby's shirt has the hole in the pocket again. (01:13:50 - 01:15:00)
Factual error: When the soldiers return to HQs, the American flag, hung vertically over the entrance, has the blue field with stars on the right. The flag, when hung vertically, is supposed to have the blue field on the left..
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: 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.
Revealing mistake: While Punisher is killing Pittsy, you can tell he is holding a dummy, not the real girl.
Factual error: Although correctly addressed as "captain" towards the end of the film, Richthofen continues to wear the rank insignia of an oberleutnant (lieutenant).
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: 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.
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.
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: 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)
Factual error: One of the women in the group picks up a piece of calcite (Iceland Spar variety). It is obviously calcite because of the very obvious rhombohedral cleavage and other visual indicators. The sample is later identified as ringwoodite. Ringwoodite is cubic with no reported cleavage. Even if it did exhibit cleavage, it would not be rhombodedral.
