Continuity mistake: When Bowen first catches up to Draco under the waterfall, he is completely soaked as he stands there and talks to him. Draco takes off flying and Bowen goes after him on his horse and is now completely dry, hair and all.
Revealing mistake: When WD-40 is parachuting onto the island at the beginning, he throws a match through his parachute. As the shot changes, you can clearly see the smoke canister that was producing the effect of the parachute being on fire, swinging from beneath the canopy.
Revealing mistake: When Tisean has just died and Stoney is getting out the car, Tisean is still breathing.
Continuity mistake: John Smith's guns can hold about six dozen bullets apiece.
Continuity mistake: In the final battle scene between Geena Davis and Craig Beirko, Beirko's character slashes Davis' character across the stomach (upper right hand side). In the next shot, the wound is located on the lower left side and in a subsequent shot, the wound has multiplied to become two wounds: one in the upper right hand side and a second in the lower left hand side.
Continuity mistake: When Campbell and Cole are inside the Chinese herbal-like shop, the woman behind the counter offers Campbell a drink. When he goes to drink it he holds the cup with two hands but in the following shot he's holding it with only his right hand. (00:14:05)
Continuity mistake: In the scene where the Graboid is pulling the truck you can see that there is a gun rack and a gun in it. Right before they are about to hit the rock you can see that the gun falls off of the gun rack. The gun goes on and off the rack between the following shots. (00:30:25)
Other mistake: Early in the movie when Shale is screening the commercial for his "services," the rolling text describing his abilities lists "Helicopter Repelling" instead of "Helicopter Rapelling".
Other mistake: As Plisken escapes in the hijacked chopper, Quervo Jones picks up a bazooka and prepares to fire on it. As Fast Eddy shoots him through the chest, watch the bazooka. You can see right through the barrel. In other words, there is no ammo in the weapon. (01:25:05)
Factual error: Throughout the movie, we can hear Ash's motorcycle shift gears, but we can see that his hands never disengage the clutch, a must do for a smooth shift like we hear.
Continuity mistake: There is one scene at a party where a guy drives off in a car. When he gets into the car, it is facing up the driveway with another car in front of it. When he drives off he drives straight ahead, without reversing down the driveway.
Continuity mistake: In one scene, Zane disturbs a lecture on terraforming at JPL and gets thrown out by security guards. Later on in the movie, somewhere in a Mexican bar, Zane and Ilana are discussing global warming. In a flashback Zane remembers the lecture at JPL.

Continuity mistake: The terrorist blow up many Jeeps when they ambush the military in the opening scenes. The problem is, they blow up more Jeeps than are in the convoy. When the terrorists steal the truck that was being escorted by the military convoy, we can see there were 3 Jeeps. But during the ambush scene, there are a lot more than that blown up by terrorists using weapons.
Factual error: When Xander's thugs are taking the Phantom up to the roof to do away with him, he breaks away and ducks into the machinery room for the elevator. In the scene the door of the room is lockable from the inside only. This door should be lockable from only the outside.
Visible crew/equipment: When Angel Marie comes up to attack Fozzie, you can very easily see the forehead of the puppeteer, as well as the T formed by the human hand merging with the puppet hand.
Plot hole: When Peyton/Darkman is showing Bridget how the liquid skin works, he drips a small amount onto his burnt finger, and it solidifies. However, when he drops it onto his finger, it magically shapes itself into a replica of a perfect, undamaged finger. This makes no sense, as it is simply a liquid and is not being molded by any forces. Hence, it should not look like a perfect finger.
Continuity mistake: During the scenes on the makeshift snowboard Jackie uses to evade the skiing soldiers, every time you see Jackie's face he is standing left foot forward on the board, but whenever you cannot see his face he is standing right foot forward. (00:19:45)
