Bob Clark's dark comedy horror, 'Children Shouldn't Play With Dead Things' (1972), is a movie I've been wanting to see for quite a while now, but never have. The story centres around a theatre troupe who carry out a necromantic ritual, as somewhat of a joke, to bring the corpse of Orville Dunworth back to life. After it seemingly fails, their director, Alan (played by Alan Ormsby, who also wrote the film) decides to take the body back to the house in which the group are staying. However, the joke turns serious when the corpses of Orville and the other people buried on the island come back to life to teach the troupe a lesson.
It's a B-movie, so obviously it might be a little silly, but B-movie or not, it certainly sounds very entertaining!
