Embryo (1976)

In the cult sci-fi flick Embryo (1976), Rock Hudson stars (against his natural type) as a modern-day Doctor Frankenstein who wants to grow a gorgeous, naked woman in his laboratory. He ultimately scores a major success when he's able to cultivate the titular microscopic being into full-grown Nicaraguan bombshell Barbara Carrera in just four and a half weeks. Doc Rock names his new beaker-spawned bosom buddy Victoria and, after laying some pipe in her, is shocked to discover that she's utterly amoral. In fact, Victoria has no qualms of turning even the slightest perceived threat into an opportunity to commit murder. The true killer here, though, is Barbara's body. Embryo is bound to lead to mass executions of sperm.
