Continuity mistake: When Lila's staff are gossiping about the "new sweetheart of America" Christian raises a glass and toasts, "Hear hear!" There is only one glass, but in the next shot Lila is holding it. Also, in the following shot, Christian is holding his hands together and no wine in sight. (00:13:45)
Continuity mistake: When Elle wakes up in her hotel, she looks out the window. Just a moment before, there was a speed-time shot of the sun rising; however, when she's looking out the window and talking in standard time, the sun's reflection is still moving awful fast.
Continuity mistake: When Natalie tells Bernie about her son, the lock of hair hanging down in front of her right eye disappears and reappears randomly throughout the scene. It's present in only about half of the frontal shots, and no shots from any other angle. (00:37:20)
Continuity mistake: When Ellen is getting up from the table after arguing with Jill, she takes her purse off the table with her right hand. In the next shot, she's shown dragging her purse across the table with her left hand.
Revealing mistake: In the scene where Ray and Eva have sex for the first time, Eva is moving underneath the blanket and you can see that she has a pair of knickers on. The couple were supposed to have just finished having sex, why would she have knickers on?
Revealing mistake: Don't worry, Aunt Sally isn't really dead. She's still breathing in the shots where people come to look at her in her coffin.
Continuity mistake: When Robert Crumb is looking at Harvey Pekar's drawings for comic-book ideas while the two eat in a restaurant, the level of the drink in Harvey's glass switches between full and two-thirds full several times.
Continuity mistake: When the monk is first teaching Kar to fight, the monk has Kar in a hold where Kar's arm is on the monk's shoulder, in the back and forth shots, Kar is holding the monk's shoulder and has his hand stretched out over the monk's shoulder. (00:53:00)
Other mistake: When Jackie meets the boss of the Interpol department in Ireland, he shows everyone some sketches, the child and then a man with a hat. If you watch the picture, it changes from a man with a hat to another man without a hat back to the man with the hat and once again back to the man without the hat. (00:22:10)
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: 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."
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: 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 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.
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: In the scene were Hans tries to hang himself, you can see that the chandelier falls down but in the next scene when O.J the owl flies underneath it, it is still there.
Audio problem: When Galleria is playing the piano by herself at school, it's obvious she really isn't playing. Her hands are moving way too slow for some of the parts and at the end, her hands are playing very low on the bass notes when the notes heard are in middle-low C range.
