The Body Snatcher
This is a classic horror movie that features two of the biggest names in the history of the genre, Bela Lugosi and Boris Karloff. It comes from the era before movies were rated for content, but it is definitely easy on the gore and violence. A ruthless doctor employs a henchman to kill people and harvest bodies for his crazy medical experiments. Creepy and awesome, and a great chance to see two of the all-time horror greats at once.
