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: 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: When Jessica Alba is getting up from the bed after sex, you can see the adhesive modesty patch covering her chest. (00:36:15)
Revealing mistake: When Henry is running to the injured civilian there is a shot where you can see his kneepad under his trousers. (00:46:20)
Revealing mistake: When Rolfe is walking down the hallway to Sally's apartment, there is an orb where the hallway is lighter colored and his legs seem to jump and undulate due to the special effect used to hide the fact that the actor is actually full-sized, walking on his knees.
Revealing mistake: When Tara Reid is being slapped around, pushed and tossed out of the cabin, we can see that it's a stunt double, by the dark hair at the front where the white wig has slipped back, exposing the double's dark hair.
Revealing mistake: When Kirk Douglas returns from his run in the park the door attendant calls him "Mr. Douglas" and then corrects himself in the next sentence after Kirk waves him off.
