From 1974 comes The Bat People, a creepy B-movie delight that stars such big name stars as Stuart Moss, Michael Pataki, Marianne McAndrew, and Paul Carr. Yes, I know. I've never heard of them either. At any rate, I watched this on Hulu and was moderately amused by it. Thus, here is my choice for tonight's Spooky Fest.
A doctor is attacked by a swarm of bats. At first, he seems fine, but his new bride insists that he go to a nearby hospital for a rabies shot. He has a violent reaction, and metamorphoses into a strange man-bat, committing a series of gruesome murders.
