Continuity mistake: When John first meets Raymond, Raymond sticks his business card in the black slot and it is big enough that it hangs over the slot. When the camera pans away from the card to go back to their conversation, it disappears. At the end of the scene it appears again, because they end on a close-up of the card. (00:15:45)
Continuity mistake: When Keaton is watching Anna take his son to school he is standing in the driveway. During the first shot his cell phone is on a clip on the side of his pants. When the shot changes to Anna in the car, then back to Keaton, his cell phone has moved to the front from the side. (00:05:40)TomDlgns
Continuity mistake: After Jonathan saves the baby from the car he goes to the funeral. In the funeral he starts talking to the baby's father and while they are talking you see a bald man with glasses pass by and glance at the baby and then in another scene you see the same bald guy pass again. (00:59:30)
Audio problem: When John Rivers is installing his new audio equipment, he says to his son "So you can watch your favourite show and I can watch my favourite show". John's mouth movements don't match what he is saying.
Visible crew/equipment: In the bookstore, when Sarah is passing boxes down to Jonathan, the boom mic drops into frame for several seconds.
Factual error: When looking at Anna's cell phone, you can see the logo for Telus, a Canadian communication company that only offers cell phone service in Canada.
Continuity mistake: When we see Anna as a 'ghost,' she is wearing a flowing, lightly colored garment, NOT what she was wearing when she died. But when we see John's ghost, he's wearing the clothes he died in, as you can assume most of the others were as they seemed to be wearing casual garments. The killer (as you could see with his last attempted victim) did not change his victims' clothing before killing them. Why then, was Anna wearing what seemed to be a night gown?
