The Film: Rabid (1977)
The Vamp: Porn star Marilyn Chambers plays Rose, who is badly injured in a nasty motorcycle accident. Experimental surgery to replace damaged skin and organs has a strange side effect that should probably come with a massive health disclaimer.
Why Are They Weird? She develops an orifice in her armpit that attacks its victims with a phallic stinger and steals their blood while wiping their memories and you already guessed David Cronenberg directed it, didn’t you?
Yes, it’s body horror 101 as she and her little friend rove around town sucking plasma and converting others into 28 Days Later-alike zomboids with a taste for flesh.
Fangs for the trivia: Cronenberg originally wanted Sissy Spacek for the lead role, but the studio torpedoed her casting because of her accent. A little film called Carrie was released while the film was shooting and to poke fun at his short-sighted bosses, Cronenberg included a poster for it in a street scene.
