Continuity mistake: In the opening scenes where the are driving home and the right front tire goes flat. Just before the Big rig truck hits them you can see that the tire is not flat. (00:07:50)
Continuity mistake: We see a close up of Gabriella slipping in some milk, but in the wide shots there is no milk or carton on the floor. (00:41:30)
Continuity mistake: When the red Ford Bronco is driven off the ferry (ignoring all the impossible factors required for it to successfully do so), it flips through the air and contacts the water going backwards, its right/rear tail light entering the water first. The closer next shot shows the truck sink somewhat as it continues to flip backward, onto its roof. The very next shot shows the interior of the truck as it enters the water right-side up and going forward as water rushes in. Denzel lurches forward and down, driving his face into the water that is about waist level. The next exterior shot is underwater as the truck now lands in the water, nose first and right-side up. It then begins the expected slow dive, nose-first. (01:52:30)
Continuity mistake: At the start of the movie the hole in the back on Sean's car vanishes in some scenes. (00:04:05)
Continuity mistake: In the first scene in Giuseppe Baldini's perfume shop, his employee comes in and starts setting three candles in a candelabra. He sets them very straight and upright, however after we cut to Guiseppe asking if he knows of Amor et Psyche and back to the shot of the candelabra again, all three candles are wonky. This is more than simple gravity could have caused. (00:27:30)
Continuity mistake: In the opening scene, Andy is seen eating a bagel, then the shot changes and she has no bagel, but when she goes down the stairs into the subway the bagel is back in her hand.
Continuity mistake: After Costello smashes Costigan's wrist he hands all of the dollars he has in his right hand. A frame later money reappears in the hand.
Visible crew/equipment: When Steven Weber and Kelly Overton find Tom Skerritt's motorcycle in the desert a crew member is visible in the chrome that runs along the red gas tank.
Continuity mistake: After Eisenheim has disappeared, literally, from stage, Uhl and the policemen search his office. There, Uhl finds Eisenheim's notebook with the design of the locket in it. There is a large tear in the middle of the paper. It disappears when the inspector looks at it again after he has found the locket in the Prince's barn. (01:31:00 - 01:31:45)
Revealing mistake: The film is set in 1997 the year of Diana's death. However there is a scene in where Tony Blair is being driven in a car and you can see a Mercedes through the rear window with an '02' number plate indicating a 2002 model vehicle.
Continuity mistake: When Barris is served in the diner, french fries are scattered over his plate. When seen again, the french fries are replaced with vegetable sides.
Factual error: At one point, a screencast of a computer screen shows a video of Barry Brickman on the desktop environment of Windows XP (operating system, developed by Microsoft, released in 2001). However, the app that plays the video is QuickTime for Mac (which runs on Mac OS only), not QuickTime for Windows (which runs on Windows XP). These two versions of QuickTime are almost identical in every respect, except for their title bar (the narrow horizontal area above the video). (00:19:15)
Continuity mistake: The shoulder buckle on the Oracle keeps switching shoulders during her trance scene.
Character mistake: In the training room, after Randall is discussed as the record holder, the students are brought to attention. All but one is standing at attention, he is in the back on the right hand side, standing at ease.
Continuity mistake: During the last few scenes in the movie, when Hannah asks Jenny if she needs help with the plane, they knock knuckles together. When the shot is taken from behind Hannah, she is shown wearing gloves, but when the shot position changes to behind Jenny, the gloves magically disappear.
Continuity mistake: In the scene where John is talking to Van Buren underneath the bar, John has a large spot on his neck, as well as a scab and red mark on his chin. These aren't present at another point in the film. (01:05:25)
Continuity mistake: In the scene after the bus rolls down (when they are at the beach), one of the girls is wearing a red bikini, but when she gets in the water it's black. (00:13:40)
Revealing mistake: After the scene with the apothecary where the two eunuchs purchased the belladonna it then cuts to Esther, and in her closeup as she lifts the silver cup to drink, there's a small white modern sticker on the underside of the cup. (01:02:00)
Continuity mistake: In the scene where Haley is sitting in the bathtub full of ice, she is wearing a black sports bra. The shot then switches to some of the girls watching a news report from the Worlds competition. It then switches back to Haley, who is now wearing a gray sports bra.
Other mistake: When Bruce and Mos Def are running through the alley near the beginning, they run past a Chinese man who slams a dumpster lid shut. Once Bruce pulls out his gun to look back, that same man starts running because he gets scared. In the next shot, he continues running, but soon stops as if he thinks filming is over. This is visible right before the camera pans to the right.
