The real story is about the wreck a ship whose last name was “Brown” as I remember. One liferaft set off with the rich people all set and comfy, leaving an officer named Rhodes in charge of an overcrowded lifeboat. He was very weak in his command. The crew just decided to throw off everyone who they could. The closer you were to them, the worse off you were. They were all pretty well let off the hook.
Hollywood, of course turned it into an excuse to throw off the brunette women and none of the blonde women. Hollywood was pretty much the Nazi ideal until the late 1980s, so it’s no suprise. Somehow, the movie managed to make the sick event even sicker.
