Some people may be surprised at the movies that are on the 10 best horror movies based on true events list. Truth can be stranger than fiction, and in the case of these movies, the truth is more terrifying that fiction. The best horror movies based on true events will make you look at things much differently after you have seen the movie.

  1. "The Exorcist" (1973). People do not realize this, but "The Exorcist" (1973) was based on a series of real events that happened in 1949. Several newspapers reported a series of strange events in a small town in Missouri from 1949 to 1951 that became the inspiration for the book and the movie.

  2. "The Exorcism of Emily Rose" (2005). Of course the names were changed to protect the real people, but this is based on a real court case. Two priests and the parents of a small girl in Germany were convicted of murder when an exorcism they performed lead to the death of a girl.

  3. "The Amityville Horror" (2005). There will always be debates about how much of this movie is real and how much was made up by George and Kathy Lutz, who wrote the book. But this is still one of the best horror movies based on true events ever made.

  4. "Texas Chainsaw Massacre" (1974). The inspiration for a sadistic killer that wore his victims' skin as clothing is based on the real story of serial killer Ed Gein. The murders and characters in the movie have been changed to make the story more brutal, but the inspiration for Leatherface was Gein.

  5. "Jeepers Creepers" (2001). This was another movie inspired by the life of serial killer Ed Gein. When Gina (Patricia Jenner) and Darry (Justin Long) enter the den of the Creeper (Jonathan Breck), they find a scene based on what the police found when they entered Gein's house. Ed Gein, like the Creeper, decorated his walls and furniture with human body parts.

  6. "The Haunting in Connecticut" (2009). The family that this story is based on has appeared in several documentaries and have described many of the incidents from the movie as being true. The plot for the movie was created by Hollywood writers, but the incidents themselves are said to be real events.

  7. "The Hills Have Eyes" (1977). It is hard to believe that this horrific story could be true, but it is. This movie is based on a clan of around 60 people that lived in the hills of Scotland in the 1600's. The rumor is that the clan killed and ate over 1,000 victims before they were brought to justice.

  8. "Open Water" (2007). This is a psychological horror movie that preys on the common human fear of the open water and sharks. It is based on the true story of a couple that were left behind by an Australian diving company and were never heard from again.

  9. "The Entity" (1981). This is one of the most bizarre movies you will ever see, and it is all based on a true story. It is a film about a woman that is repeatedly beaten and raped by a violent ghost. The part that the movie producers did make up was when other people witnessed the attacks. The real victim, Doris Bither, had the physical evidence of bruises to back her story. But the two researchers who spent hours and hours with Bither, and even managed to get strange photos of ghostly activity, never saw her get attacked. This is definitely one of the best horror movies based on true events.

  10. "Jaws" (1975). Author Peter Benchley once read a news story about a great white shark that killed swimmers off the coast of New Jersey for a twelve day stretch in 1916. That news story became the inspiration for one of the best horror movies based on true events of all time - "Jaws" (1975).
