Deliberate mistake: If the captain is bending over the girl to protect her and the line is at about mouth height for him, the line couldn't have gone straight through his mouth. Instead, it would have run from the back of his lower jaw up and horizontally to his left eye. (00:05:00)
Trivia: The studio and producer Joel Silver reportedly called for major re-writes of the script shortly before shooting began. Many of the actors had signed up based on the original script, titled "Chimera", which contained far less violence and supernatural elements, and instead was a psychological drama about what happens to a salvage crew when they are stranded in the middle of the ocean. Much of the cast wasn't informed that the script had been almost completely altered into a more generic supernatural-horror/slasher film until just before they showed up to begin filming, leaving many of them disheartened and disgruntled.
