Greg Goodsell here! This h’yar film is known as RABID, aka RAGE, as this opus was known in French-speaking Canada.
This was director David Cronenberg's follow-up to his international horror hit THEY CAME FROM WITHIN in 1975, and would capitalize on his theme of "body horror."
Here we go -- this is the main reason we remember RABID today - porn superstar MARILYN CHAMBERS! From being the model that adorns the "Ivory Snow" detergent box, Chambers would rocket to stardom in the Mitchell Brothers' BEHIND THE GREEN DOOR in 1972! RABID was her bid to court more mainstream roles, but it failed -- she went straight back into starring in XXX-rated features well into her fifties! We imagine the adult film industry didn't treat Marilyn all that well -- her daughter discovered her dead several days after the fact in her trailer in Santa Clarita, aged only 56 years old in 2009.
In typical Cronenberg fashion, he names this plastic surgery clinic after something not many people know about. If you look up the word "keloid," this would be the absolute LAST thing to name your plastic surgery clinic!
