I was about 5 years old or so, and someone in our family thought it was a good idea to take a child to see the movie DEATH SHIP at the drive-in. I don't remember much of the plot, but I remember people in one boat boarding another boat (the titular "Death Ship"). Of course, all sorts of bad things happened to them. The one thing I remember QUITE VIVIDLY was the scene where a guy finds a fishing net full of skeletons…and proceeds to "fall" into it. As he struggles among the bone pile, someone or something else is lowering the fishing net…slowly, very slowly…into the water. To this day, my biggest fear is drowning at sea.
