Ghost Ship (2002)

Revealing mistake: When the crew are getting ready to load up the gold, one of the crew slams the crate lid making the gold bars "move".

Epps: Have you told anyone else about this?
Ferriman: Not a living soul.

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.

Question: Who killed the young girl, or did she hang herself?
