Rabid is a 1977 independent body horror film written and directed by David Cronenberg. An international co-production of Canada and the United States, the film stars Marilyn Chambers in the lead role, supported by Frank Moore, Joe Silver, and Howard Ryshpan. Chambers plays a woman who, after being injured in a motorcycle accident and undergoing a surgical operation, develops an orifice under one of her armpits that hides a phallic/clitoral stinger she uses to feed on people's blood. Those she bites become infected, and then feed upon others, spreading the disease exponentially. The result is massive chaos, starting in the Quebec countryside, and ending up in Montreal. Rabid made $1 million in Canada, making it one of the highest-grossing Canadian films of all time. A remake of the same name, directed by Jen and Sylvia Soska, was released in 2019.

Body horror, or biological horror, is a subgenre of horror fiction that intentionally showcases grotesque or psychologically disturbing violations of the human body or to any other creature. These violations may manifest through aberrant sex, mutations, mutilation, zombification, gratuitous violence, disease, or unnatural movements of the body. Body horror was a description originally applied to an emerging subgenre of North American horror films, but has roots in early Gothic literature and has expanded to include other media.
