Frank Henenlotter (born August 29, 1950 in New York City), is an American screenwriter, film director and film historian.
 He is known primarily for his horror comedies, though he would prefer to be classified as an "exploitation" filmmaker (rather than horror).
 "I never felt that I made ‘horror films’, he has said.
 "I always felt that I made exploitation films.
 Exploitation films have an attitude more than anything – an attitude that you don’t find with mainstream Hollywood productions.
 They’re a little ruder, a little raunchier, they deal with material people don’t usually touch on, whether it’s sex or drugs or rock and roll."

Body horror, biological horror, organic horror or visceral horror is horror fiction in which the horror is principally derived from the unnatural graphic transformation, degeneration or destruction of the physical body.
 Such works may deal with decay, disease, parasitism, mutation or mutilation.
 Other types of body horror include unnatural movements or the anatomically incorrect placement of limbs to create "monsters" from human body parts.
 David Cronenberg, Frank Henenlotter, Brian Yuzna, Stuart Gordon, Lloyd Kaufman, and Clive Barker are notable directors of this genre.
 The term "body horror" was coined with the "Body Horror" theme issue of the University of Glasgow film journal "Screen" (vol.
 27, no. 1, January–February 1986), containing several essays on the subject.
