Watch Death Ship

"Death Ship" (1980) is a British-Canadian horror movie about a haunted ship. In the movie, survivors of a ship wreck board the haunted ship. On board, they find artifacts from the 1930's -- including some that reveal the ship was a Nazi prison ship. Even worse, the ghosts of its crew and prisoners are still around. To make matters still worse, one spirit possesses the captain of the wrecked ship. He then begins attacking the other survivors.
