Trivia

 * Most of the monsters that appeared in the movies are reference to many numerous horror movie characters and icons, as well as the mythological ones. The most notable example would be Fornicus (who is a reference to Pinhead), The Dolls (who are a reference to The Strangers), The Buckner Family (who are a reference to Leatherface' family, having an aspect of being undead like Jason Voorhees),  & the Yurei (who is either a reference to Sadako/Samara or Kayako).
 * The monsters also bears many similarities with the creatures from the SCP Foundation.
 * A unicorn is spotted as one of the few known monsters, during the System Purge, it is seen killing a worker of the Organization. Many fans and viewers suggest this to be a joke.
 * Boomer zombie, Witch zombie, Hunter zombie & Tank zombie from Left 4 Dead made cameos as one of the monsters. The directors of the movie originally planned to released a DLC exclusive of Cabin in the Woods cabin and facility for Left 4 Dead. This idea was scrapped due to the fact that the company producing the DLC went bankrupt.
