I remember seeing an old sci-fi movie where there was a scene on a boat. The guy is tortured by putting him up on the lookout ledge. Then a storm comes and the guy is continuously struck by lightning until only his skeleton is left when they take the body down.
i can't remember the specifics of the sci-fi movie but I think in that scene it was a scientist that was persecuted aboard the ship for some reason.
I think the people and the ship was late 1700's or 1800s style.
