Other: There is a scene in which Christian Slater shoots 9 or 10 shots out of a 6-shooter. There is no possible way that he could have had time to reload in the time allotted.

Continuity: In the gun fight in the mine shaft, Christian Slater pulls the hammer down on his pistol, then seconds later it's back up.

Continuity: In the scene in the copper mine, Christian Slater accidentally arms the bomb. As it counts down it is at 26 minutes. Later it counts down to 22 minutes. When John Travolta finds the bomb and begins stroking it the timer is back to 26 minutes.

Continuity: In the big fight scene in the end John Travolta gets hit in the face and has blood all over his face and the front of his shirt.  This keeps disappearing.

Continuity: In the scene where Christian Slater and the ranger are about radioing for help in the ranger's truck, the enemy helicopter comes from behind a ridge and shoots at them. They get out of the way, and the bullet fire continues and hits the truck on the driver side door, the roof above, and then the ground after that. In the next scene, you can clearly see bullet holes on the hood, going from front to back, but the fire was from right to left.
