Blood Harvest (1987)

Jill, visiting home from college, arrives to find her parents missing, and their home vandalized. Soon, matters take a turn for the worse, when she finds herself stalked, and her friends disappearing one by one.

This film is probably most notorious for the bizarre stunt casting of 60s pop icon Tiny Tim in such a sleazy, violent movie. That’s the sort of authentic weirdness that can only result from a situation where no one seemed to care how a work would be received by an audience, so long as it simply was received.
