Body horror, biological horror, organic horror or venereal horror is horror fiction in which the horror is principally derived from the graphic destruction or degeneration of the body. Such works may deal with disease, decay, parasitism, mutilation, or mutation. Other types of body horror include unnatural movements, or the anatomically incorrect placement of limbs to create 'monsters' out of human body parts. David Cronenberg is one of the notable directors of the genre.

David Paul Cronenberg, OC, FRSC (born March 15, 1943) is a Canadian filmmaker, screenwriter and actor. He is one of the principal originators of what is commonly known as the body horror or venereal horror genre. This style of filmmaking explores people's fears of bodily transformation and infection. In his films, the psychological is typically intertwined with the physical. In the first half of his career, he explored these themes mostly through horror and science fiction, although his work has since expanded beyond these genres. He has been called "the most audacious and challenging narrative director in the English-speaking world."

Born in Toronto, Canada, Cronenberg was the son of Esther (born Sumberg), a musician, and Milton Cronenberg, a writer and editor. His family has been described as "a nurturing middle class family." He began writing as a child and wrote constantly. He attended high school at Harbord Collegiate Institute. A keen interest in science, especially botany and lepidopterology, led him to enter the Honours Science program the University of Toronto in 1963, but he switched to Honors English Language and Literature later in his first year. Cronenberg's fascination with the film Winter Kept Us Warm (1966) by classmate David Secter sparked his interest in film. He began frequenting film camera rental houses, learning art of filmmaking and made two 16mm films (Transfer and From the Drain). Inspired by the New York underground film scene, he founded the Toronto Film Co-op with Iain Ewing and Ivan Reitman. After taking a year off to travel in Europe, he returned to Canada in 1967, graduating from University College at the top of his class.
