Body horror or biological horror is a subgenre of horror that intentionally showcases grotesque or psychologically disturbing violations of the human body. 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.
It’s all the other wonderful stuff that makes the movie. Director Scott Derrickson isn’t afraid to let his imagination run wild everything from acid trips to body horror to Inception called and they want their movie back is featured.
