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)
Factual error: The whole Bowfinger scenario is impossible. They are using a 35mm Panavision cine camera which cannot be focused through the lens; it needs precise measurements on the set in order to be properly in register. Then there are the light readings required to ensure proper exposure. Wouldn't Kit Ramsay notice the man with the light meter, or the one with the tape recorder? Both measurements would have to be done with him or an identically dressed and made up stand-in (a "lighting double") on the spot. Then there is the sound. Any sound recordist worth his salary will have the microphone within centimetres of his subject, and he'll have a boom operator keeping in there. We don't even see a microphone in use! Please don't tell me this is based on the clandestine filming of Mary Pickford during her Russian visit: that was done with old black and white film which has very wide tolerance to exposure and most of all it was silent, and she was aware of the camera crew, she just thought they were news crews. (And the results were rubbish anyway).
Revealing mistake: During the bedroom scene with Felicity and Fat Bastard you can clearly see the air hose that fills his suit when he rolls over in the bed. (00:49:10)
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)
Visible crew/equipment: After he gets beaten up by his father, Ricky looks in the mirror. On the left edge you can see a bit of the camera, then it moves away. (01:10:10)
Other mistake: In the beginning of the movie, when you first see Mary-Kate (aka Mel) and Ashley (aka Ally), Mary-Kate walks off without ever closing her locker.
Factual error: Ashley Judd is convicted of murdering her husband for the insurance money and that would make it a first degree murder charge (first degree meaning she planned the murder). Because of that there is no way she would have been eligible for parole after just 6 or 7 years.
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.
Revealing mistake: When Sonny is on the payphone, you can see Julian mouthing something to the guy on the payphone behind Adam. The guy is giving him instructions.
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.
Continuity mistake: Terence Stamp takes out a pursuing vehicle by reversing his own car into it at high speed and pushing it over a cliff. When he subsequently drives off, amazingly there's no damage at all to the rear of his car. Shortly before, it is peppered with gunshot holes which mysteriously disappear.
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.
Factual error: A copy of Miles Davis' album "Tutu" is sitting on a counter. Odd since the recording wasn't made until 1986.
Factual error: This movie is set in 1935. Back then, executions were done by hanging. The Louisiana Legislature changed the method from hanging to electrocution in 1940.
