The HMS Bounty that just sank was built for the 1962 movie and was a more modern ship that looked like one built in the 18th century. The original HMS Bounty was burned/scuttled off Pitcairn Island (South Pacific) following the mutiny of its crew. There's a third Bounty built for another movie.

It is important to know what the crew thought they knew before making judgments regarding their judgment. You don't know what you don't know.
