Marilyn Chambers does plenty of sucking in Rabid (1977). The only problem is that it’s through her armpit. The ’70s porn queen goes mainstream as a gal whose emergency skin grafts turn her into a vampire. Writer/director David Cronenberg really indulges his bizarre bodily obsessions, as Chambers sports a new vagina under her arm that hides a blood-sucking clitoris. She’s soon infecting an entire city and turning the population into a bunch of murderous lunatics. You won’t be feeling too sane yourself as you ogle the young ya-yas of the pretty Patient Zero.
