Deliberate mistake: At the beginning and especially at the end, Julianna Margulies spends extensive time in the ocean, wearing nothing but cargo pants and a T-shirt. Considering the movie takes place just off the Bering Strait, wouldn't she have quickly frozen to death? (01:21:05)
Deliberate mistake: When Rachel researches Anna Morgan in the Seattle PI newspaper archives she looks through hardback books. The PI has not only been using microfilm and computer archives for years but archives are available on line at www.seattlepi.com.
Deliberate mistake: As the sub rises backwards to the surface, the stern emerges from the water at a steep angle, then rises near-vertically so that the boat is virtually standing on the tip of its bow. Anything left loose on a countertop would surely fall off. But when the boat falls onto its belly, a close-up shows a pistol sliding off a sink counter into the hand of the Captain- because it's dramatic and cool looking, yet extremely improbable- especially considering that an open tin of shaving foam, its lid and a foam brush all lay on the same counter, undisturbed.

Deliberate mistake: The sex scene between Paul and Marcy is broken up with a shot of Karen dying alone in the toolshed. The shot is well-lit, but we saw Marcy closing the door when she put Karen back in the shed, leaving the shed virtually pitch dark. So where is the light coming from? (01:02:35)
Deliberate mistake: There is blood all over the back of the couch that's supposed to be from the neck cutting, however there is not a trace of blood on May's dress or anywhere else but her hands. (01:13:30)
Deliberate mistake: When the woman is attempting to escape from the elevator, it dislodges and falls down, so then the actress is facing the ground...but when her arm hits the floor, the floor itself bends. If you watch the DVD with the commentary on, the director points out that it was a break away floor in case the actress' head accidentally snapped forward, to avoid any injury. (00:08:00)
Deliberate mistake: The entire time they spend in the trench, before they attack, Quinn has a white sheepskin jacket. It rains throughout the film yet with all the mud about you would think in about a day that this jacket would turn dark brown. It is still fairly white even when Quinn dies.
