Continuity mistake: In the first film, it is mentioned several times that Kevin is 8 years old. However, in this film it is stated that he is 10. When his parents are in the Miami airport security office, they say that he was left alone last Christmas. That would make him 9. Both films take place the same days, from about three days before Christmas until Christmas morning, so even if Kevin is born around Christmas time this is still a mistake.
Revealing mistake: When Dracula flies into the room to stop his brides from devouring Jonathan, the board carrying him is visible. (00:34:10)
Continuity mistake: During the infamous leg un-crossing scene when Sharon Stone is being interrogated, a cigarette in her hand disappears and then reappears.
Continuity mistake: The tiger bites the seat off the suitor's trousers, allowing the viewer to see his polka-heart boxers. When we see the tiger in the courtyard, he has a part of the same boxer shorts in his mouth. So if he bit off the seat of the trousers, shouldn't he have purple cloth in his mouth? (00:11:45)
Continuity mistake: When Adam Banks is playing in one of the games, he scores a goal and his teammates on the bench stand up and cheer when he scores. Problem is, Adam Banks is on the bench too.
Revealing mistake: When the kids are burying Gus, his supposedly dead face flinches when they shovel dirt on him.
Continuity mistake: In the convenience store, Link weezes the juice and gets slurpee all over his shirt. He gets kicked out and leaves, but 2 seconds later he comes back in the door and says, "I'll be back". At that point he has nothing on his shirt at all and it's completely dry.
Continuity mistake: When Meryl Streep "blasts" Goldie Hawn with the shotgun and Goldie falls into the pool of water, she falls in backwards. However, when we see her get up, she is getting up from a face-down position. (01:05:25 - 01:07:10)
Continuity mistake: Just before Batman takes his mask off at the end, the black makeup around his eyes vanishes while the mask is still on. (01:48:20)
Continuity mistake: When Pinhead is just about to start killing everyone in The Boiler Room nightclub, a man catches the first hooked chain that Pinhead unleashes. Yet when you look closely as you see the man holding the chain there is no hook, but a piece of wire.
Revealing mistake: After Mary Robert jumps out of the car, you can see the stunt double falling for her.
Continuity mistake: In his cameo in this film, Tim Burton is holding something in his left hand that looks like a remote of some sort when we first see him in the background. Then the shot changes to Debbie and back to Tim, but this time he doesn't have it. Then the shot changes to Debbie again and then back to Tim, and he reaches to his far right and picks it up.
Revealing mistake: When the terrorists drop the dead body out the aircraft door, look closely at the aeroplane just beneath the door, you can see the reflection of the mat the stuntman lands on, as well as the spotters around it.
Other mistake: During the scene where Markus and Jackie are making love for the first time, as she is straddled on top of him, you can see that she that she is wearing knickers (panties).
Other mistake: In the scene following the robbery, the four young men, led by Tupac Shakur and Omar Epps, run into a brick court, walled on four sides. Shakur states he's going to keep the gun, despite suggestions that they ditch it. He has a revolver stuck in his jeans, by his left hip. When he is challenged about keeping the gun, he pulls another revolver from his pocket, scuffles with one of his friends and shoots him in the chest - all the while the grip of the other identical revolver is in view.
Suggested correction: It looked like old man Quilles' gun that he must've taken off-screen after he killed him.
If you look at the movie again, Quiles' gun was a long nose revolver, Raheem's gun was a snub nose.
Other mistake: Towards the end where they steal the chip, they are detected and about a million security guards are all running around, yet 30 seconds later, the only security guard is one man with a shotgun. What happened to their big army of security guards? (01:41:30 - 01:42:55)
Continuity mistake: In the scene where Gabriel Byrne is dancing around the fire with the travellers, he is wearing a large leather coat. After the police come and go, he's no longer wearing the coat. In the same scene, it shifts from night to day quite quickly, too quickly to be a sunrise.
Revealing mistake: In the part it shows Ash getting sucked into the time portal you can see the wire he is hanging from. (00:02:45)
Factual error: During the big Newsies rally when Medda is singing "High Times", as she is swinging, lighted exit signs can be seen. I don't believe that those were around in 1899.
