Horror films also have interesting behind-the-scenes stories of their own, which are just as memorable as the films. Many of the most famous horror movies have had interesting backstories, whether it be unusual casting, high production values, or real-life inspirations and production problems. Read on to discover movies that would be considered creepy and have very true and totally bizarre backstories.
The Exorcist (1973)

Director William Friedkin pursued realism throughout production, using practical effects and keeping parts of the set unusually cold to capture visible breath during exorcism scenes.
Jaws (1975)

Mechanical problems often plagued the shark, and Spielberg had to show it less than he would have liked during filming. The creative adjustment finally added tension and was one of the highlights of the film.
The Shining (1980)

Many takes were shot by Stanley Kubrick, and some parts are said to have been shot dozens of times. Later, Shelley Duvall talked about how difficult the making of the film was and how intense the emotions were.
Poltergeist (1982)

In the swimming pool sequence, several scenes were shot with real human skeletons. Later, actress JoBeth Williams confirmed this choice and said that it was more expensive at the time to have artificial skeletons.
The Blair Witch Project (1999)

During the filming, the filmmakers allowed for improvisation and gave the actors little information. The marketing campaign also drew a false line between fiction and reality, such that some early viewers thought that it was true.
The Descent (2005)

The cave sets were purposely designed to be cramped and uncomfortable. Director Neil Marshall wanted the actors to experience some of the same unease and claustrophobia faced by their characters.
Paranormal Activity (2007)

The film was produced on an estimated budget of about $15,000, and later turned into one of those really profitable movies, earning hundreds of millions of dollars around the globe.
Get Out (2017)

Jordan Peele originally intended to write a darker ending for the movie, but changed it. That conclusion was given in the released film, which didn’t contradict but differed from the one the original had.
The Conjuring (2013)

The movie was based on the records of Ed & Lorraine Warren, the paranormal investigators. The film fictionalised events, but the story was inspired by the investigation of the experiences of the Perron family.
