Corrected entry: When the AV-8B Harrier II fighter duo attacks the trucks on the bridge, they fire sidewinder missiles to destroy the bridge. Sidewinder missiles are not air-to-ground missiles and cannot be fired at ground targets as there is no heat source to lock onto. This task would have called for bombs or rockets.
Corrected entry: When Arnold is being followed by the bad guys and uses the cigarette-pack camera to watch them, the lens is toward the bottom of the pack as he holds it. However when he puts the pack on the sink in the bathroom later, although it's in an upside-down position compared to before, the feed in his sunglasses is still right-side up as before.
Corrected entry: The 6 foot 2 Arnold manages to squeeze his steroid pumped body into a harrier jet, which is only mean to host people of horse jockey stature (around 5'8").
Corrected entry: A real Harrier jet can only hover for approx 30 seconds. It needs water 150 gallons to cool the engine. In the movie it hovers for a few minutes, which would be impossible because it would have run out of coolant.
Corrected entry: After Aziz has shot up the bathroom stalls, you can see the resultant bullet holes in the doors. While doing this he is standing at quite an oblique angle to the doors and as such you would expect to see elongated/oval shaped bullet holes in the doors from their angle of entry. instead you see the perfectly round holes produced by a real gun obviously being fired from an off-screen location at ninety degrees to the doors.
Corrected entry: The exterior shot, from behind the Harrier, towards the building shows that all the windows are mirrored glass. Harry would only have seen his reflection on the side of the building and couldn't have known where the terrorists were, or even if he knew which floor, whether there were any hostages or other innocent people inside.
Corrected entry: Opening shot of the lake shows the water as unfrozen. Then Arnold is cutting through the gate under a frozen lake. He then cuts through the ice with a knife and exits the frozen lake.
Corrected entry: When Arnie is breaking through the ice at the beginning of the film, it's obviously just wax. Watch the way it breaks when he's cutting the hole to crawl out of, and also how buoyant it is. Also, listen to the sound effects. It sounds like they didn't even bother covering up the wax sound with the sound of ice cracking.
Corrected entry: When the bad guy is stuck on the missile on the rail of the Harrier, and Arnold shoots it, it carries the bad guy into the building and out the other side. Modern missiles accelerate at more than 2000 G's - the Sidewinder weighs less than 200 lbs, and thrust is more than 40,000. So he would have been fried by the backwash as it left without him.

Corrected entry: After Arnold hands Helen the machine gun after they escape capture in the camp, Helen accidentally drops the gun, where-after, for a number of seconds, it shows a number of enemy terrorists being killed by the spray of the bullets from the gun bouncing down the stairway. One, no gun will normally fire without holding down the trigger, obviously Helen does not know how to set auto-fire [most machine-guns don't have it] so the sequence is incredibly unlikely to begin with. Two, that kind of machine gun will dump all of its ammo in about 2 seconds if it was stuck, they have this scene going on for 10 or fifteen seconds, an impossibility.
Corrected entry: Harry and his partner followed Simon after his lunch with Helen on Chinatown. The restaurant was pretty crowded, so how come they knew who to follow? Simon would not come out of the restaurant together with Helen, because he had a 'secret agent' role to play. He must have instructed her to go out a few minutes before or after him, so Arnie would have no way to know that he was the guy to follow. (00:52:30)
Corrected entry: At the beginning of the movie, when Arnold is running down the snow covered hill with the guys chasing him on skis, he shoots at them with a semi-automatic. He changes magazines once, but I counted 24 shots after that change, and there was no shot of him changing magazines again, nor any chance to do so. There was no extended magazine on the gun, so about the most rounds he could have fired (being liberal) would have been 19 shots. (00:13:00)
Corrected entry: In the scene where Arnie is asking for the missing page in his wife's phone conversations, Arnie punches out the window of their car. In the next shot when they get in and drive away, the window shows no sign of being damaged (no fragments of glass etc.), nor does Tom's hair move in the subsequent wind that should be blowing through the broken window.
Corrected entry: In the scene where the terrorist jumps the motorcycle from the hotel into the pool on the other building's rooftop, why didn't Tom Arnold and the rest of the law enforcement officers just arrest him when he exited the building on the ground floor? He had to leave that building at some point and it was right across the street from where they were.
Corrected entry: When the Crimson Jihad is making its video while in the Florida Keys, the statement is made that "We will rain down fire on 1 U.S. city each week" unless their demands are met. The very next day, they are in Miami with the second nuke and claiming that they are all ready to die for their cause. Who would be left to 'rain down fire' if they all died in that building?
Corrected entry: During the stripdance scene in the hotel room, Tasker is using what looks a whole lot like a walkman to play the recording of a man talking. Watch as the first number of times he plays and stops the tape, he presses buttons along the face of the player. Then when he replays "Now lie on the bed, and close your eyes" he uses regular playback buttons that stick out on the side of the walkman. I've never seen a walkman with two sets of controls on the body of the machine.
