I just recently saw a rather old and odd movie about a serial killer who may or may not be a vampire.
The movie was called "Martin" and I had never even heard of it before, but it was recommended to me by someone.
At times disturbing, but always rather interesting, and some of the flashbacks in black and white are downright creepy.
He has no fangs, so his method of drinking people's blood is by sneaking up to them, jabbing them with a needle full of sedatives, and then cutting them with razor blades (and in one case-- jabbing the victim with a broken piece of wood) which causes them to bleed and then he slurps up the blood. Often times he gets naked with the naked victim, as he is drinking their blood.
Sunlight, garlic, crosses, and priests seem to have no effect on him. My impression of him is that he is a very socially awkward serial killer who is obsessed with blood.
I wonder if the television series "Dexter" is loosely based on this old (1970s) movie?
Feel free to post any movie that creeps you out for Halloween in this thread...
