Revealing mistake: In the railroad yard shootout, Seagal jumps on a railroad work cart. He then kicks at a post to propel himself down the track, but one can easily see the pull cable/rope just inside the near rail, in the lower right hand corner of the screen. (00:44:05)
Revealing mistake: In the motel room when Alec Baldwin hits Natalie, she hits the mirror, which shatters. She then has cuts all over her face, but there's no bleeding. All the cuts look like they have dried blood already. (01:16:50)
Revealing mistake: Sarah is reading her daughter a story about Snow White and the Seven Dwarves, but the cover of the book is Little Red Riding Hood.
Revealing mistake: When Dr. Kendricks closes the eyes of the dead woman, you can see on woman's neck, that she is still breathing. (01:05:10)
Revealing mistake: Rex the dog leaps through the protective wire netting around the baseball practice area. As he jumps through, you can see the netting split apart and that the edges of the 'broken' wire mesh are protected with some duct tape.
Revealing mistake: After the assembly where Grace speaks to the Dogville people she walks home chained to her wheel. However, the wheel that's supposed to be so heavy that she can hardly move around gets pulled along with the chain hanging through a little. (02:05:10)
Revealing mistake: The movie takes place over the course of several years, as large segments of time pass between scenes of Will and Jane meeting at the airport, and other encounters. Thus, it is rather jarring to notice that their twelve year old children, Ben and Claire, don't appear to age at all. Young adolescents usually change in appearance quite drastically as they mature.
Revealing mistake: Throughout the film when we see wads of £50 notes they are quite fake as the print of the queen looks far too dark and the colours are off. Surely it wouldn't have been too much bother to put one real note on top of each wad? (01:06:50)
Revealing mistake: When Fitch is giving Marley the final offer on the $500K check, notice that the trolley is in motion by looking out the windows. When it cuts to a frontal shot of Fitch, look behind him through the windshield and you will see a car in front of a tree just above Fitch's right shoulder. Look close and you will notice that the car is not moving away from the trolley as if the trolley was stopped, yet it cuts back to Marley and we see that the trolley is indeed still moving.
Revealing mistake: When Shuya impales a commando with a pipe, the strap holding the pipe in place is visible, when he turns towards the camera.
Revealing mistake: The movie takes place immediately after World War II. When David is boarding a flight, a Swiss Air jumbo jet is seen taxing down a runway in the background.
Revealing mistake: Although the film is supposed to take place in New England, and there are constant references to how "Americans" do things, all of the license plates are from British Columbia.
Revealing mistake: When Frank yells stop to Marion, you can see the marks on the road from a previous take. (01:05:20)
Revealing mistake: At the end of the movie when the Grandpa and grandson are tackled after being given the 'fortune cookies' right at the moment of impact the little boy has been replaced by a stunt double which is a grown man dressed in the same clothes. Like the dude has wrinkles and doesn't even resemble the boy at all.
Revealing mistake: In the scene where they are at the rooftop escaping from the snakes and at the part where the mom screams, you can see her smile a bit.
Revealing mistake: Why does the railroad station look so old? It should be almost new at the time of the film.
Revealing mistake: It is really obvious Jackie Chan was on a wire when holding onto Roy at the end. His body floats and moves in a very unnatural way.
Revealing mistake: When Darcy has caught up to Elizabeth in the end and they are kissing in the street with the police cars around them, if you look at the side of the cars, you can see that these Las Vegas, Nevada police officers are driving cars from the Provo, Utah police force (where the movie was primarily filmed). (01:36:50)
Revealing mistake: The car that falls into the water has a surprising lack of damage after such a long tumble.
Revealing mistake: When Jessica Alba is getting up from the bed after sex, you can see the adhesive modesty patch covering her chest. (00:36:15)
