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.

Continuity: In the scene when Slater and the ranger are getting into the boat there is a mysterious pair of binoculars that keeps appearing and disappearing.

Other: When Terry stands in the valley and the stealth passes above her, you can clearly see that a part of the B2 disappears behind a mountain that is several kilometers away before it has flown just a hundred metres away from Terry.

Continuity: Near the end of the movie, the underground nuclear bomb is detonated, creating shock waves and rippling in the ground beneath the Hummer getaway vehicle. The ripples are huge and come in waves, yet when the explosion subsides, and they drive away, the dirt road isn't rippled or disturbed at all.

Continuity: After the nuclear bomb is detonated, the helicopter spins out of control and crashes in front of the Hummer. Moments later, a camera shot from behind the Hummer shows the road in front of it to be clear, and the Hummer drives away without the helicopter being anywhere in sight.

Continuity: When Slater has captured the Hummer, Travolta slams into Slater's car which wrecks the right front light. Seconds later when Travolta arrives at the mine the front light is in one piece.

Continuity: When Kelly fires at the hummer, you see that he punctures the gas tank. On hummers, the gas tank is in the middle of the underside. What he shot was the floorboard.

Continuity: When Hale and Terry get into the Zodiac on the river, in some of the shots there is a pair of binoculars on the seat, in some there isn't.

Continuity: In the closing fight sequence between Slater and Travolta, Travolta takes out a $20 bill, folded, and sets it under the remote for the nuke. Later, when they show the remote again, the bill is shown unfolded, in fact it is flat. When Christian picks the scorched bill off of the plant it is still flat.

Continuity: In the scene where Terry and Hale first meet, Terry says "You're under arrest until we can get this sorted out", and puts the handcuffs on his right wrist. When he kicks her off, the handcuffs are on his left wrist.

Plot hole: Slater decides to render the nuke inert by punching in the wrong code three times. However, when he does this, the nuke becomes armed, and Travolta reveals that he is one step ahead by having used a special kind of circuit board to produce this result. Two questions: One, once Slater has armed one nuke, why not arm them all? You've got nothing to lose, and you can keep Travolta from getting them for whatever evil purpose he has in mind. Slater plans to send them all to the bottom of the copper mine anyway, so just arm them all. Two, Travolta later arms a nuke himself, and then smashes the keypad with his gun. Well, if you can do that, why doesn't Slater just smash all the keypads as soon as he gets the nukes? Travolta would be defeated; movie over.

Continuity: When Hale throws the gas bomb at Deakins' hummer, you notice that the damage to the right side of the front end from Kelly ramming the other hummer is magically gone.

Factual error: In the scene where Christian Slater's character shoots down the Huey Helicopter, before it hits the ground the sound of the rotors/turbine changes to an Aerospatiale SA341 Gazelle helicopter. Much like the Chinook, the Gazelle has a VERY distinctive rotor/turbine sound.

Continuity: Toward the end of the movie, after the nuke has been armed in the mine and both groups are driving Hummers, John Travolta switches off the engine and informs his passengers that when the nuke goes off, the electro-magnetic pulse (EMP) will disable any vehicle that is running. Little does John (and apparently the movie's director) know, but EMP will fry any and all electrical circuits, whether or not the vehicle is running.

Continuity: Towards the end of the movie, there is a nuclear bomb with a counter displaying  a digital readout of the time countdown.  After using several different camera shots and angles, the timer displays "26:00" then 18:00" then "23:00".

Factual error: When Travolta is deep down in the mine shaft, he uses a two-way radio to talk to his guys upstairs. I know from personal experience, and from being in the military that two-way radios, no matter how much power output they put out, cannot talk for more than 100 feet max in an enclosed area such a mine with thick walls, let alone 2,000 ft (the distance the elevator travels in the mine).
