#25 Rabid (1977)
I wouldn't say I'm a huge fan of Cronenberg, especially the later era, but The Brood and Videodrome are two of my favorites. Even by those standards, this one is weird: an experimental skin graft causes a woman to develop a vampire armpit stinger that infects victims with super-rabies. I can't find anything that says Cronenberg was inspired by Typhoid Mary, but there's a lot of her story in Marilyn Chambers' unsettling performance, as she alternates between instinctive predation and blank innocence.
