Factual error: A hard pack of Winston cigarettes is shown, but these were not available in 1953.
Plot hole: When Bryan is shuffled in at "The Baywatch" as one of the dancing extras, wouldn't the director of the film notice that one of his beach dancers (Bryan) is actually dressed for cold weather rather than a day at the beach? He's wearing sweats and a hooded sweatshirt, and he stands out like a sore thumb with all those girls in bikinis around him.
Continuity mistake: The cracks on Henry's diploma after the missed shot change between closeups and totals.
Continuity mistake: When Donnie steals Chuckie's clothes and glasses, Chuckie puts on Donnie's shorts and complains about his eyesight. But later in the movie, when he doesn't have his glasses, it seems he can see just fine. Then, when he gets his glasses back, he says something like "I can see again."
Other mistake: In the scene where Dennis Quaid has just rescued Sharon Stone from the devil's throat, they are running through the woods to get back to the house. Quaid says to Stone that they will take the Jeep. He is referring to the Jeep Grand Cherokee that he drives throughout the film. It's a newer model, possibly a Limited, with flashy star-shaped chrome rims. When they get to the house, they see that the Jeep is up in flames. The camera hangs on the vehicle for a solid 3-5 seconds. From this camera shot, it is extremely obvious that the flaming Jeep has rims that, although still star-shaped, are styled quite differently and are most likely the alloy wheel that was very popular on the older Laredo edition from the early to mid-90's.
Continuity mistake: When Champion receives the dog, the alignment of the box changes after the first shot. (00:05:10)
Visible crew/equipment: In the scene in which Waldo & his co-worker are sorting parcels at the post office, an umbrella type photographic light diffuser can be seen reflected in a television set perched on a shelf in the background.
Continuity mistake: When Rob stops Katya and pushes her against the wall some of Katya's hair lies on her chin. The hair disappears and appears between the following shots. (00:29:40)
Factual error: How can a gun being *thrown at* a car window (as Adrian did with the thug's gun in the car chase sequence) possibly shatter the glass? No shots fired, no full body weight being thrown - just the gun.
Continuity mistake: In the beginning of the movie when the two guys steal the lady's purse and pull off her fake arm, the arm they grab is the woman's left one, but the arm the guy is swinging around is a right arm.
Continuity mistake: Nino gets trussed up in silver duct tape. The boy gets bundled over the shoulders of one of the bad guys, and you can see that there is only a small amount of tape around his legs. They go straight inside the meat packing factory and suddenly in the next shot, there is a huge amount of tape around the boy's legs.
Continuity mistake: In the scene where Frannie and Detective Malloy are standing outside the police car, after Frannie was picked up by the two police officers, outside her apartment, you can see a girl with a white shirt with black sleeves and a very short skirt passing by. After a few seconds, Detective Malloy goes back into the car and you can see the exact same girl passing by at the same direction as before and she even wears the exact same clothes.
Factual error: Sarah states that Namibia is on the Ivory Coast, while in fact, it is on the Skeleton Coast in southern Africa.
Continuity mistake: The first time at the station, Sweetu looks back at the camera representing Aman with a confused look on her face, mouth open a little bit, teeth clenched. During the Heartbeat instrumental song when they show a flashback of the same moment with Aman in the shot, Sweetu looks at him with a big smile on her face. You can see this because when her face turns her mouth is visibly wide open and her lips are curled upward. (00:10:35 - 00:20:40)
Factual error: All UK driving test instructors must wear a yellow reflective waistcoat or jacket while instructing someone during their driving test. This was still true in 2002 when the film was shot.
Continuity mistake: As Nicolas Cage is smoking a cigarette in his car when his daughter comes into view for the 1st time. The camera angle flips between him, him with her in the background, to his key, back to him, and back to him with her in the background. Each time the angle changes so does the length of his cigarette. The time span is only a matter of 10-15 secs as she walks up and then starts to walk away, but his cigarette ends up being longer than when she walked up. (00:25:25)
Continuity mistake: As the New Main Street Singers are performing their second song at the show, you can see Parker Posey pretend to use her guitar as a shotgun. The strap for the guitar drops from her shoulder down to her right forearm when she does this. When the shot changes the strap is back up over her shoulder. (01:01:40)
Continuity mistake: At the very beginning of the movie, in the shot where Val Kilmer is unconscious and lying down on the ground, he first appears with his right hand facing up, then facing down, then facing up again.
Revealing mistake: When Dae-su enters the room of one of his nemesis, his computer screen shows information about the stock exchange. The Internet address on the screen is: C:/DocumentsandSettings/[.]/OldBoy/[.], which would be a link to a folder on that computer, not an Internet address.
Audio problem: When John confronts Selima about the baby and they've walked out of the house and down the steps, from the side of her face you can see Selima's lips moving even though there is no sound coming out.
