1) The document discusses several subgenres of horror films including action horror, body horror, comedy horror, gothic horror, and natural horror. 2) It provides brief definitions and examples for each subgenre. For instance, it states that action horror combines elements of horror and action films like gunfights and chases. 3) Some other subgenres mentioned are slasher films, splatter films, and zombie films, with notes about their common themes and story elements.

1. Horror sub genres

2. Action horror
A subgenre combining the intrusion of an evil force, event, or supernatural
personage of horror movies with the gunfights and frenetic chases of the action
genre. Themes or elements often prevalent in typical action-horror films include
gore, demons, vicious animals, vampires and, most commonly, zombies. This
category also fuses the fantasy genre.

3. Body horror
In which the horror is principally derived from the graphic destruction
or degeneration of the body. 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

4. Comedy Horror
Combines the elements of comedy and horror fiction. The comedy horror genre almost
always inevitably crosses over with the black comedy genre. The short story "The
Legend of Sleepy Hollow" by Washington Irving is cited as "the first great comedy-
horror story"

5. Gothic horror
Gothic horror is a type of story that contains elements of goth and horror. At times it
may have romance that unfolds in the setting of a horror tale, usually suspenseful.
Some of the earliest horror movies were of this sub-genre.

6. Natural horror
A sub-genre of horror films "featuring nature running amok in the form of mutated
beasts, carnivorous insects, and normally harmless animals or plants turned into
cold-blooded killers." This genre may sometimes overlap with the science fiction
and action/adventure genre.

7. Relies on characters' fears, guilt, beliefs, eerie sound effects, relevant
music, emotional instability and at times, the supernatural and
ghosts, to build tension and further the plot.

8. Often revolves around subjects that include but are not limited to killer
aliens, mad scientists, and/or experiments gone wrong.

9. Often revolves around a psychopathic
killer stalking and killing a sequence of
victims in a graphically violent manner,
mainly with a cutting tool such as a
knife or axe. Slasher films may at times
overlap with the crime, mystery and
thriller genre, and they are not all of
the horror genre.

10. Splatter film
These films deliberately focus on graphic portrayals of gore and
graphic violence. Through the use of special effects and excessive
blood and guts, they tend to display an overt interest in the
vulnerability of the human body and the theatricality of its
mutilation. Not all splatter films are slashers, and not all splatter
films are horrors.

11. Zombie film
Zombie films feature creatures who are usually portrayed as
either reanimated corpses or mindless human beings. Distinct
sub-genres have evolved, such as the "zombie comedy" or the
"zombie apocalypse".
