Corrected entry: Near the end when Nadi is drinking the tea that Behrani put medicine in to kill her, she cries as if she knew that he was killing her. She has no reason to cry; she doesn't know her son is dead or that she is being poisoned by her own husband.
Correction: She has just been through a very emotional ordeal (being held hostage in her bathroom, etc.), and it seems that she is very emotional to begin with. She could have suspected something was wrong, since her husband came in to give her the tea she reacted as if she was suspicious. This is a character portrayal, not a movie mistake.
Corrected entry: In the scene where Lester (the cop) comes back to the shed where he's staying with Kathy, he's obviously just come back from work and leaves right after that to go to see his wife and kids. Then when Kathy goes into her trunk, she finds his police belt and gun. Why did he put his equipment in her trunk? They have no contact with each other between these two scenes, so he couldn't have given these things to her.
Correction: Lester went to work using Kathy's car (see the scene where his wife is trying to beat him up), so he probably took off his stuff and put it in its trunk after work, before coming back to the shack, and left it there.
Corrected entry: The house in which the action takes place has only one floor; when Ben Kingsley goes to his bedroom from the front door he walks straight to it. But in one scene, when he and his wife go to their bedroom to make love, they go via stairs and a landing, neither of which have appeared in the film before, nor do they appear again.
Correction: The house is actually made of two levels and not one floor. So there are two little steps you have to climb to get from living room to bed rooms. You can see that during the whole movie.
Corrected entry: In the scene where the officer is holding the family in the bathroom, he puts a chair against the outside of the door to secure it. This is useless because the bathroom door opens in, not out.
Correction: I don't believe that the chair was put in front of the bathroom door to secure it. It couldn't- the door opens inward and it is very obvious by the hinge which is seen from the inside and when the door is opened. I think the deputy put the chair in front of the door so if the family tried to open the door he will hear them when the chair falls. The deputy had a gun and they knew that but he didn't sit outside the door the whole night so this was a way he could tell if they tried to sneak out while he was in another room.
