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.
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.
Continuity mistake: During the chase at the Borgo Pass, there are several shots of Dracula inside the wooden box, buried up to the neck in the earth of his homeland. However, when Dracula bursts out of the box outside the castle, the box falls apart completely, but hardly any earth falls out. (01:53:10 - 01:56:50)
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.
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.
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.
Continuity mistake: When Eddie Murphy is lying in bed with the woman, she is lying on her side snuggled up next to him. When he lifts up the covers to reveal her feet (and check out her toes), they are pointed straight up as if she were lying on her back.
Continuity mistake: As Jack Kelly rides the horse near the end of the "Santa Fe" sequence, his hat is waving behind him. When it cuts to a different angle the hat is on his head. Note: This was a specific detail put in by the director, symbolizing the boy's mental transition from New York to Santa Fe. However, it failed and is commonly seen as an editing mistake.
Continuity mistake: In the scene where Mr. Blonde is pouring gasoline over the cop, the cop's legs are flying around trying to kick him. Later, we see that the cop's legs are still taped to the chair.
Continuity mistake: In the first scene in Woody Harrelson's flat, Rosie Perez is in bed. Her top falls down, all but showing her breast; but in the next shot, she has covered herself up, but without moving her arms.
Continuity mistake: During the tango scene, the girl's earrings keep appearing and disappearing.
Continuity mistake: Liz Hurley shoots one of the FBI agents seated next to Rane, in the background the other agent can be seen with make-up on waiting to be shot next.
Continuity mistake: Just after the doctor started the post mortem on that little girl, the front of his gown is covered with blood. Yet, a few seconds later, after the two other guys appear, his gown looks better, with less blood. And during the whole post mortem scene, the blood spot actually changes its size a few times. (00:17:55 - 00:19:55)
Continuity mistake: When Rocky and Colt go to the bathroom to attack Hammer after he drank the laxative, Colt thrusts a plunger to Hammer's face. As Colt thrusts it backwards, Hammer's face gets pulled forward, sending his ponytail over his head. In the next shot his hair is neat and tidy, not over his head.
Continuity mistake: In the final shoot-out scene where Clint Eastwood kills 5 men in rapid succession, Clint crouches and exchanges gunfire with two deputies who are standing side-by-side. A blood stain suddenly appears on the abdomen of the younger deputy on the left, but there is no bullet hole, it does not coincide with any gunshot sound effect, and the deputy does not react to the wound. A moment later, as Clint continues firing, both deputies topple over backwards.
