Corrected entry: Sandra Bullock is watching as her husband gets killed in the accident at the end of the movie, and the accident takes place on Wednesday. But at the beginning of the movie, a cop informs her that her husband is dead, and it's supposed to be Thursday. If she was there when it happened, why would he be telling her about her husband's death one day later?
Corrected entry: I'm not sure what type of mistake you would count this as, but there's no way a policeman/authority of any kind would come to someone's home, tell them their husband has died, and then just leave, giving them a calling card. Even if not to comfort her, there would be formal identifying or other official arrangements to be made.
Correction: He gave her his card specifically to make arrangements AFTER she comes to grips with what has happened. That's perfectly plausible.
Corrected entry: The daughter runs through the right right hand pane of glass, but when her father sweeps up, the broken pane is on the left.
Correction: No, she went through the left pane, which is exactly the one that Jim is cleaning up later.
Corrected entry: When the Doctor injects Linda with the drug, it's very obviously her upper right arm near the shoulder. But later when she wakes up in her own home, and frantically checks her arms to see if there are injection marks (meaning did it actually happen), she only pulls her sleeves up just above both elbows. She looks for needle marks only up to her elbows and just above, which was far below where the actual injection took place. Since she remembered the incident, she would have remembered where the shot was given.
Correction: Not necessarily. You can definitely remember only certain parts of an event, you may even be subconsciously blocking a certain aspect of the event. This is highly plausible and not at all a mistake. Even if it was, it's a character mistake, not a movie mistake.
Correction: She was looking for the marks of them carrying her away and strapping her down.
Corrected entry: Sandra Bullock puts the dead bird in the trash can on Thursday, the first day of the movie. She takes the lid off and discovers the rotting carcass earlier in the week, so before the bird would have been put in there at all.
Correction: The bird isn't put in the trash on Thursday, it is put in the trash during one of her 'Jim is alive days' on the Monday. When she opens the trash later to check, she confirms that she wasn't dreaming when the maggots and flies are on the bird.
Correction: Because she left, and no one knew she was there.

Why wouldn't she have called 911 after the accident? Makes no sense she would go home and not report it. She also called her husband back after she got his message the day after he died and she left him a voicemail. Why would she do that if she knew he was dead?
