Shivers (1975) - Blu-ray - new

By 1975 David Cronenberg was already nine years into his directing career when he brought the world one of his first bloody, body horror classics. We were shocked to learn that Ivan Reitman, the mastermind behind Ghostbusters, produced this one. 

Per IMDB: "The residents of a suburban high-rise apartment building are infected by parasites that turn them into mindless nymphomaniac fiends."
