Factual error: How is it that when Sly comes out of the freezing, icy water, his hair and clothes are bone dry? I don't know too much about hypothermia, but I would imagine that his fairly thin sweater isn't wind proof. I'm sure by the time the movie ended, he would be suffering from more symptoms of hypothermia other than chattering teeth.
Continuity mistake: When Stallone is told to climb up and retrieve the first suitcase of money, we see him reach a rather open landing with plenty of room to kneel and break open the suitcase. Once his partner (still below with the terrorists) screams "They're gonna kill you," and the terrorists start shooting up at him, the camera pans up to show him standing with his back to the rocks on a tiny ledge with barely enough space to stand.
Plot hole: This happens after Gabe has killed the guy in the cavern and is reaching for the radio. We hear Frank trying to reach them, so they must be on the same frequency. Then, Hal finds out that a bomb has been planted, grabs a radio from the bad guys and starts yelling for Gabe to get out of the cavern because of the bomb. Why didn't Frank hear any of this on his headset?
Continuity mistake: Shortly after Frank is shot, Caroline Goodall's character checks the fuel gauge of the helicopter, and puts the kybosh on any ideas about flying around looking for the third case, as the helicopter only has enough fuel to get them down from the mountain. Later, John Lithgow, having kidnapped Janine Turner, flies around for ages, and the helicopter stays in the air for a surprisingly long time.
Other mistake: When Gabe and the bad guy are fighting on the helicopter on the side of the cliff look carefully at the rotor shaft - you can clearly see that it has changed. Earlier when it was on the ground you see the shaft and the scissors on it. When it is upside down the scissors have vanished and the rotor shaft has a different look to it.
Audio problem: When Gabe is yelling at Qualen to drop Jesse off on the mountain at the end, he yells "over there" and points to his right. however, he points to the right with the hand holding the walkie talkies as he is yelling over there without any trail off of his voice. his voice can be heard loud and clear as if he was talking straight into the walkie talkie.shortdanzr
Plot hole: During the finale you see Stallone's character attach the helicopter to the ladder. He then runs away from the helicopter, and away from the ladder. Even if he does run round in a semi-circle, (unlikely from what we see), they show the helicopter go over his head as he jumps off the hill onto the ladder. The helicopter then pulls the ladder off the cliff face. Based on the length of the helicopter's cable it must have kept going for an awful long distance!
Continuity mistake: When Rex Linn is looking for the third case, there is another shot of the screen shown. We can see his EMPTY left hand by his side. When the camera switches to a front view, he is suddenly holding a huge machine gun.
