Other mistake: When Ace rescues the dog and replaces it with a toy dog, the toy dog is in an impossible position. Ace had to place it there when the door was still open, but if the door was closed after that the man would have knocked it over. (00:03:25)
Other mistake: When Adam comes in and says "when I woke up this morning, the pain was gone", Connie is mouthing his lines behind him.
Visible crew/equipment: On the train, Jack hears Mac saying the track isn't finished, then Jack becomes aware of the broken emergency stop button. When Jack walks back over to Annie and tells her they have to jump, we can see the reflection of the standing camera operator on the right door's window, and the reflection of a crouching crew member (possibly boom operator) on the left door's window. Definitely crew given they're meant to be alone on the train. (01:45:55)
Revealing mistake: When The Mask is dancing with Tina and he turns her into a human tornado while spinning her around, none of the onlookers in the crowd show the slightest bit of amazement at the impossible feat that just occurred in front of them, indicating that the extras were not directed to react to the special effects.
Factual error: The terrorist with the AK47 is unaware of the fact that a Harrier is hovering just outside the window until he slowly turns and see it there. He does a double take when he sees the Harrier just five metres away! A Harrier is an incredibly loud aircraft; you can hear them from three kilometers away. At that range the floor would shake with the noise and he would have been in no doubt whatever that he had been under attack for some time.
Revealing mistake: When running towards the "bear attack", Sean activates the Guyver. Close ups of the armor attaching itself to his body show that's not really Sean as his arm and leg are both seen not moving even though he's running to where the attack is occurring.
Continuity mistake: In the scene at the bar with Gideon when the black guy pours Gideon a drink it is only about 1/3 full. When Gideon drinks it in the next shot it is almost full.
Visible crew/equipment: Throughout the movie, in the shots of the guys on the alien planet, the white reflector screens and film crew's reflections are visible in their sunglasses. (00:40:20)
Other mistake: As the Veridian star is destroyed, Picard raises his hand to supposedly shield his eyes from the sun's light, but he is looking in the wrong direction; the sun is behind him, and there is no light on the rest of the front of his body.
Other mistake: When in the tub in Arkansas, Wyatt is bare chested. In bed with Josie he's suddenly sprouted a lush garden of chest hair.
Continuity mistake: In the movie Christie Swanson drives a BMW 3 series coupe. In the scene where they were making love the car suddenly changes to a four door model then back to a two door. (00:06:10)
Factual error: A bunch of troops are in heavy camouflage in helicopters, going to an assignment. The officer in charge tells them to take their dog tags off and empty their pockets of anything that could identify them. This is silly: first, in troop helicopters, the troops wouldn't be able to hear the officer's voice - it's too noisy - and second, this would be ingrained in them, to remove dog tags etc, and would have been done back at the base, before they left.
Deliberate mistake: Twice in this film Axel is shot at by multiple gunmen using automatic weapons at close range - and they all miss. In the Earthquake theme ride the bullets ricochet of the rails at Axel's feet. Why are they all aiming low? Why don't they raise their aim? In the park outside he hides behind a perfectly ordinary park bench and the bullets hit the wooden slats. Not one goes through the open spaces between them? I know bad guys can't shoot straight in the movies, but this is ridiculous ...
Continuity mistake: In the film Jeff Douglas is out to kill the five leading kingpins of "the Hand". After he gets the first three, he goes after the last two who are hiding together. But the two fall out and one (Manter) shoots the other one (Kowalski) dead. Later, when he catches up with Manter, he doesn't kill him but lets him live to face justice (though he does die at the end). After catching Manter, he acts like it is the end of his "quest", yet does not know that Kowalski is already dead, and therefore should be out looking for him, not stopping at Manter's capture.
Revealing mistake: In the fight between Julie and Ned, when she does the last kick to take him down, it's obvious that she doesn't actually kick him.
Continuity mistake: At the beginning of the wedding day scene when Mallory is throwing the red doll off the bridge, her nails are long and manicured, but later in the same scene you can see that they are bitten down to the quick. (00:19:55 - 00:21:50)
Continuity mistake: When Frank is going to look for a disguise he drives into a parking meter. The way the parking meter lies on the hood of the car changes between shots. (00:18:20)
Continuity mistake: After Leon rescues Mathilda from the SWAT team and dodges the snipers, he shoots out a ventilation fan to make an escape route. He gets off two shots before we see the vent, but when it does we see about 7 bullet holes around the vent. Then the camera goes back to Leon as he continues firing. When the camera switches back, the holes around the vent are different. (01:27:05)
Visible crew/equipment: When Angela and Shame are in a car chase from the bad dudes, Shame turns the jeep around 180 degrees and then drives over the bad guys' car. While the jeep is driving off the bad guys' car, you can clearly see the jeep driving off some kind of ramp set behind the car. You can just see them driving down it.
Continuity mistake: In the very first scene when Seagal first gets off the helicopter we see that he's wearing a navy blue shirt tucked into his jeans. In the next shot he's shown wearing the yellow suit but instead has a white shirt on underneath instead of the navy blue one.
