Revealing mistake: There are 4 different vehicles in the movie that have the same license plate number (2PCE275). The first is on a white car owned by the gang member that shoots Max. Then you see the same plate number on the pickup truck of the skinheads that are harrassing Gary. Then you see the same plate on Steven Seagal's car as he drives away from saving Gary from the skinheads (incidentally, the front plate on his car is different than the back plate). The last time you see the same plate is on a Lexus driven by the guy in the all white suit who is going to buy the cocaine.
Continuity mistake: Right after Jim has his nightmare while sleeping in the car, he looks around for Grace, who is standing outside the car looking at scenery. When Jim sees her, she has her arms crossed over her chest. The next shot, with Jim walking around the car, she has her arms by her side, and immediately after, the shot with Jim approaching her, she has her arms crossed again. All this took place in about 2 seconds, not enough time to drop her arms and recross them exactly the same way as the first shot. (00:19:35)
Continuity mistake: When Eddie is about to be interrogated by the Turks, he's tied up with his hat on. In the next shot his hat is off, and just as the Turk administers the truth shot he rips Eddie's hat of his head.
Continuity mistake: In Metropolis on the bridge, Doomsday grabs a soldier and breaks his neck and skull. In that shot, the soldier's arms are inside Doomsday's hand and his hair is a light brown or gray. But then when the shot changes as Doomsday begins to throw the soldier to the side, the soldier's arms are suddenly outside of Doomsday's hand, and his hair is now black. (00:17:10)
Continuity mistake: The left tail light of Sadie's car is broken when she picks up the unfortunate hitchhiker. The light works when she turns left off the road. (00:36:20 - 00:38:35)
Continuity mistake: When Sarah is on the beach in a gown and slippers, she takes the slippers off, then they are back on, then seen off, on the sand, again.
Continuity mistake: All wide shots of Hrothgar's hall show it in the outer ward of his fortress, about two hundred metres from the towers on the edge of the cliff, with open ground on three sides and an embankment on the fourth. But later several characters are able to step straight out of the hall onto a balcony that overhangs the cliffs and sea below.
Revealing mistake: When Billy is looking at Nick's driver's license, for sex it says F for female.
Factual error: No army flight from Georgia to Iraq would cross central Mexico.
Continuity mistake: When Stan is asking his wife to use the dildo on him, you can see it changing direction between shots. (00:17:25 - 00:18:00)
Factual error: SSgt Gallegos asks Carter what other ammo he has, and he responds 5.65. No such ammo exists - M16/M4 uses 5.56 rounds. (01:17:41)
Continuity mistake: When the Teens land in Africa their parachutes land on the ground. We see a shot of Africans and then back to the Teens. The parachutes have disappeared.
Visible crew/equipment: At the shootout in the trailer park near the end, the redneck neighbour comes out of his trailer and his shotgun jams. Immediately after, he is shot with a machine gun mounted in the back of a white Mustang. Right at the end of his expletive-filled final line, you can see the safety cable from the pulley that jerks him backward through the wall behind him. (01:19:55)
Continuity mistake: In the opening fight scene, Dolph Lundgren's character is wearing a watch when he takes up his position against the Mongolian champion, but this disappears as soon as the actual fight begins.
Continuity mistake: When Andy Konsong discovers his brother's mutilated body in the bloody swimming pool, he vomits, then tries calling for help on his cellphone. As he makes his call, the gigantic crocodile lunges out of the pool and bites off Andy's arm, cellphone and all, above the elbow. Andy screams, staggers and lands on his back, but his only injury thus far is his severed right arm. His mouth is not bloody at all, nor should it be. The camera cuts to another angle as the crocodile lunges a second time; but, before it even enters the frame and bites into his legs, Andy's mouth is suddenly full of blood, his teeth are bloody, and blood is streaming down his chin, even though he has suffered no abdominal injuries.
