The Cottage gets an honorable mention.

David gets an honorable mention.

The Cottage is #10.

The psycho killer is modelled after Leatherface, including his backstory and making human masks.

The farmer uses a pick-axe to kill at least one character.

The farmer uses a shovel to cut half of a characters head off, the same happened in Day of the Dead with a zombie on the receiving end of a shovel.

The skull and spine removal scene is similar to a sequence in Predator.

The Farmer hides among the mummified heads, like a sight gag Igor does in this movie.
