Continuity mistake: In the bedroom scene the girl is holding a clear cup full of beer. The camera goes off her and when it comes back she is holding a blue cup. The camera goes back off her then on her and the cup is clear again. [This mistake does not appear in the unrated version - the blue cup scenes were shot specifically to secure an R rating from the MPAA because the contents are obscured.]. (00:13:20)
Other mistake: In the scene where the kids are shooting arrows and the coach gets hit by one, they send a girl to call 911. If you look closely and follow her in the background, after she runs a few yards, she slows down and eventually stops and stands there playing with her hair. Talk about help... (00:57:05)
Factual error: In the montage sequence showing Drew Barrymore hanging out with the math club, they have a Pi poster with 3.1457869986. Only the first 3 digits are actually correct. (Pi = 3.1415926535897...) (00:25:20)
Continuity mistake: During the first scene set in a prison cell, as Martin Luxford (played by Hugo Speer) is about to be released, there is a glitter ball made from an orange covered in tin foil. It is rotating first one way and then the other, as it has been spun by hand. As the film action cuts between the two characters, the ball mysteriously changes direction without having slowed down and at one point appears stopped, having previously been rotating rather fast.
Other mistake: When Catherine breaks into Crown's house, her assistants immediately get to work on the security panel. When the first assistant touches the panel, it falls off the wall and he has to quickly push it back into place.
Continuity mistake: In the very last scene of the movie where Chris O'Donnell and Renee Zellweger are on the terrace taking their vows, Renee is holding a bouquet. In one shot it is a bouquet of pink flowers, then it changes to a bouquet of yellow flowers and keeps switching back and forth throughout the scene.
Other mistake: During the scene where the Japanese are being rounded up and taken to the internment camp, the camera is panning over the crowds of people walking down the street. Half way through this scene, there is a woman and a little girl, who seems to be carrying a stuffed Elmo, hardly appropriate for the time period.
Continuity mistake: Every time they show the outside of the bookstore, on the left you see the same adult drying a child's tears. (00:17:55)
Revealing mistake: Candace's eyes are moving and she is breathing after allegedly having been shot and killed.
Factual error: The movie is set in the 1860s. During a performance for English guests, Anna has the King's children perform "Bicycle Built For Two". That song, otherwise known as "Daisy Belle" was written by Harry Dacre in 1892. (00:57:50)
Continuity mistake: The licence plate of the taxi which hits Sebastian in the end changes during the shot. (01:27:35)
Continuity mistake: When she goes through the lasers it takes 2 minutes to get to the mask, but it only takes 30 seconds to get back.
Visible crew/equipment: When Homer follows Rose Rose inside after finding out she's pregnant, there is a visible "T" taped on the floor for him to stand on.
Continuity mistake: When he is playing Tetris, he is playing a different game every time. (00:43:35)
Continuity mistake: The first time Matthew Perry's in Neve Campbell's apartment before he realises she thinks he's gay, he fills two glasses of wine in two very different glasses. He hands one to her and holds the other himself, in the next shot they hold different glasses, then again in the third.
Continuity mistake: When Parkis the detective comes to give his first report Maurice is shaving. The shaving cream on Maurice's face keeps appearing and disappearing throughout the scene, most obviously when he looks aroud the corner. (00:23:40)
Continuity mistake: In the shoe shop Carla's blouse changes from pink to beige. (00:12:40)
Factual error: Early in the movie when the interior of the downed aircraft is shown (underwater in Chesapeake Bay), with the eerie picture of Dutch's wife and the congresswoman's husband sitting underwater in first class with their hair waving slowly in the current, they are shown on the right side of the aircraft (the left side as we are looking at them, but the right side of the plane proper). Yet, when the airline representative is discussing this "problem" (non-married-to-each-other people apparently flying as a couple), they are announced as sitting in row X (don't remember), seats A and B. Aircraft seating is always done from left to right - i.e., the A and B seats would be on the other, or left, side of the aircraft.
Factual error: In the scene where the fire department responds to the fire, the engine is 42. Yet all the fireman's hats say 6. The engine company, station etc. would all be the same number so their helmets should have also been 42.
Continuity mistake: When the Austrian Emperor and Gustav's father die on the same day Gustav puts their photographs on a sideboard. The close-up of Gustav's father's picture shows a white background, in contrast to all wide shots. (00:44:15)
