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?

Factual error: The gold bars that the crew finds must be some new type of light weight gold. There's no way that Julianna could stuff a gold bar in her back pocket and then pull it out and toss it on the table and Greer simply tosses it back and forth like it was plastic. A gold bar weighs around 27 pounds, you definitely wouldn't be tossing it around.

Continuity: When Epps first walks into Katie's cabin, there is a straw hat underneath a suitcase on top of the clothes rack. Yet when Epps gets up again after looking at the dress, the hat is now on top of the suitcase without her having moved it.

Revealing: In the beginning of the movie where the line cuts the dancers in half, blood is visible on the dress of one of the dancers before the line cuts her. This is best viewed in slow motion on the DVD.

Deliberate "mistake": When the passengers are cut by the wire while dancing, some of the clothing on the torsos defies gravity. A man's coat tails and pants fall but a woman's dress stays put when nothing would have held it from falling from her lower half in the same way.
