Continuity mistake: When Vince leaves the freezer and is making his way onto the elevator, he is carrying a Baretta model pistol. When he shoots as the elevator doors are closing the camera cuts to a Glock model pistol, then back to the Baretta again. When the elevator reaches the upper level, the woman picks up the remains of the backfired pistol and it is back to the Glock. (01:21:15 - 01:24:30)
Factual error: In the scene in Costa's apartment after the failed baiting ploy, Costa describes himself as a loner who "bought a gun for a false sense of security", appeared to have had it with him during the evening, and gave the impression that he bought it after he witnessed the murder. Although IlIeana mightn't know, the Montreal police in the room might (should) have wondered about this. Even if legal, it is very difficult to acquire a restricted weapon (handgun) in Canada, the process taking one month to as many as six or more for clearance and permits, let alone courses and examinations. In addition, concealed carry of a weapon is prohibited for civilians. (01:00:25)
Other mistake: When Sarah Michelle Gellar is on the bus with her boyfriend, she sees Kayako face looking at her in the window reflection and panics. When she looks back at the window she sees the normal reflection of her face. Trouble is, her reflection is turning her head and looking side to side, whilst Gellar herself is looking straight and not moving her head at all.Gavin Jackson
Continuity mistake: When Emily is spying on Cody on the sightseeing bus, she sits down and the camera goes to a close up of her face and we see small worm like camera device comes out of the right side of her sunglasses, but when it cuts to the next shot, further back from her face, we can see the device has disappeared even though no time has passed between shots.

Continuity mistake: A montage scene of newspaper headlines early on has March 12, 1939 as the date. Much later in the film, Jude Law asks Gwyneth Paltrow the date so he can calculate the position of a star. She responds "March 2" but there is absolutely nothing to indicate that nearly a year has passed.
Continuity mistake: Towards the end of the film Nicole Kidman is having her wedding photos taken. The photographer poses her for the shot, but when he actually takes the photo, the background has changed. When he poses her, there are just trees and bushes behind her, but when he takes the photo, the trees and bushes are gone and people are walking around.
Factual error: A headline from the Pantagraph (an Illinois newspaper) dated 19 December 2001, is shown in big letters to read, "Latest Florida recount shows Gore won election." In fact, no edition of the Pentagraph has ever featured an article that claimed this. The only time those words appeared in that newspaper was in small print over a letter to the editor dated 5 December 2001.
Continuity mistake: Ashley Judd is sitting in a bar with Andy Garcia when an ex boyfriend walks in. She says to Andy, "I do not get involved with ex-boyfriends." During that line the camera is to her left and she is holding a drink almost to her mouth. While she says the word "involved," the camera switches to her right side and she is not holding a drink.
