Horror has always been an iconic genre. There's something fascinating about watching paranormal terrors and serial killers, especially from the safety of our own couch. Even for those based on a true story, we are still separated from the fear by a screen. However, for those who make the movies, that is not the case. They live and breathe these movies for months, and, sometimes, the paranormal activity becomes very real to them.

There have been claims by many actors, directors, and crew workers that some of the sets of the horror movies they've worked on were actually haunted. From mysterious bruising to coincidental deaths, the terror didn't stop when the cameras stopped rolling, or even when the workers left the set.

Here are 10 horror movie film locations that are supposedly haunted!

10 The Innkeepers

Innkeepers (1)
Dark Sky Films

The Innkeepers, released in 2011, follows two of the employees of the once great Yankee Pedlar Inn. Claire and Luke are both ghost enthusiasts, and are interested in the hotel's history of paranormal activity. In particular, Claire wants to investigate Madeline O'Malley, a bride who hanged herself after her partner didn't follow through with their wedding. The original hotel owners hid her body in the basement, and it remained there to the day. When a medium checks in and warns Claire not to venture into the basement, she does the exact opposite, and must come to face the consequences of her actions.

Almost the entire movie was shot in the real, historic Yankee Pedlar Inn in Torrington, Connecticut. There were complaints on the set of various evidence of paranormal activity, such as the lights turning on and off, doors opening and closing by themselves, and the phone frequently ringing with no one on the other end.

9 The Nun

New Line Cinema

The Nun, released in 2018, is a prequel to The Conjuring that takes place in a monastery in Romania. When two nuns are attacked by an evil entity, one of them is killed by it and another kills herself after the encounter. The Vatican sends Father Burke and Sister Irene to investigate, and the two discover that the castle that is now the monastery was home to the Duke of St. Carta, who was obsessed with the occult and summed on a demon to the location. It had been sealed away, but it's now running rampant again. Father Burke and Sister Irene must find a way to seal it away again before it kills them both.

The movie was shot in various historic areas in Romania. Despite the set being blessed by a Roman Catholic priest, the director, Corin Hardy, couldn't escape the terrifying experiences that would happen during filming. While in a Romanian castle, Hardy claimed to have seen two apparitions. When he walked into a side room to get out of the way of the camera, he noticed two men sitting at a table. However, when he looked back to speak to them, they were gone, which should have been impossible with Hardy standing in the only doorway.

8 Poltergeist

Poltergeist movie
Metro-Goldwyn-Mayer

Poltergeist, released in 1982, follows a family that lives in a planned community in California and starts to experience strange events, starting with their youngest daughter, Carol Anne, talking to the empty static on their television. The odd occurrences start to become sinister, with a tree coming alive and grabbing their son, Robbie, and a portal opening that lures Carol Anne inside. After consulting with a parapsychologist, it's revealed that they're dealing with poltergeists, and that the community was built over an old cemetery. Diane and Steven send the rest of their kids away and must try and retrieve Carol Anne, as well as get rid of the poltergeists.

The original Poltergeist, filmed in Agoura Hills, as well as the sequels, are said to be cursed after director Steven Spielberg and Tobe Hooper decided to use real skeletons in the movie. There were an abundance of dangerous set accidents throughout the filming of the entire trilogy, as well as a series of deaths from the crew to the actors. Dominique Dunne was strangled to death by her ex-boyfriend after the release of the first movie, Will Sampson died from a kidney transplant, Julianne Beck died from stomach cancer, and Heather O'Rourke died from septic shock at the age of just twelve years old.

7 The Possession

The Possession
Lionsgate

The Possession, released in 2012, follows a divorcing couple and their children as their youngest, Em, finds a mysterious box at a yard sale. She becomes obsessed with the box, hearing it speak to her and attacking anyone that tries to take it from her. Her father, Clyde, does his research and finds that it's a dybbuk box, a container for a powerful dybbuk spirit. Despite Clyde's attempts to be rid of it, Em is always called back to it, and eventually, it possesses her completely. The family, along with Rabbi Tzadok, must perform an exorcism on her before it's too late.

The movie is based off of a true story, and parts of it were filmed in a former mental institution, Riverview Hospital, in British Columbia. Jeffrey Dean Morgan, who played Clyde, previously considered himself a skeptic before the movie, but admitted to unnatural phenomena on set like light bulbs exploding, strange cold drafts, and hair-raising atmospheres. Most distinctively, the storage room where all the props were kept burned to the ground without any explanation.

6 The Exorcism of Emily Rose

Screen Gems

The Exorcism of Emily Rose, released in 2005, is loosely based on a case in which a priest was charged with homicidal negligence after performing an exorcism on a young woman who ultimately died. In the movie, Father Richard Moore tells the story of Emily Rose, a 19-year-old college student that he believed was possessed, to defend himself in court. The opposition insists that there was a medical reasoning for Emily's death, but between Moore's descriptions, a recording of the exorcism, and frightening events following those involved with the trial, it's becomes easier to believe in otherworldly causes.

The various filming locations of the movie aren't particularly unique, but the hauntings that took place on them are. Cast members complained of television and radios turning themselves on and off in late hours of the night. The star that played Emily, Jennifer Carpenter, claimed that her radio would come on at three every night, always playing the chorus of "Alive" by Pearl Jam.

5 The Omen

The 1976 supernatural horror The Omen
20th Century Fox

The Omen, originally released in 1976, follows a diplomatic married couple who, when their baby dies, are convinced to take in a baby whose mother died in childbirth. As the child, Damien grows older, troubling events follow him, like his nanny hanging herself at his fifth birthday party. Robert, his father, is warned by Father Brennan that he believes Damian is the antichrist, and if left unchecked, will kill both him and his wife, as well as her unborn child. Despite Father Brennan later being crushed by a pole, Robert refuses to believe him. It's not until tragedy after tragedy occurs that he realizes that something needs to be done.

The movie was mostly filmed in the UK, at Bishops Park and Guildford Cathedral, as well as parts in Italy. However, the horrors followed the people involved with the movie off set. Within a few weeks, Gregory Peck's plane was struck by lightning on his way to London, and then producer Mace Neufeld's plane on the way to L.A. was also struck by lightning. Later, writer David Seltzer's plane was struck by lightning, as well. As if that wasn't enough, Harvey Bernard, who was in Rome, was nearly stuck by lightning, too. The animals on set were unnaturally aggressive as well, turning and attacking their trainers. The day after filming, the zookeeper of the location was killed by a lion. But, most horrifically, special effects' director, John Richardson and his assistant, Liz Moore, were in a car accident in the Netherlands. Richardson made it out relatively unscathed, but Moore was decapitated in an extremely similar way to a scene in the movie.

4 Rosemary's Baby

Paramount Pictures

Rosemary's Baby, released in 1968, is the story of a young couple that move into a large renaissance revival building, the Bramford. The two, Guy and Rosemary, meet their elderly neighbors, Minnie and Roman Castevet, who take a strange interest in them. The couple decide that they want to have a baby, but on the night they were meant to conceive, Rosemary was drugged and has "hallucinations" of being raped by a demonic presence, though Guy denies it ever happened. Odd circumstances continue you to follow her through her pregnancy, and Rosemary soon realizes that she can't trust anyone around her.

The movie was shot at the Dakota apartments in Central Park West. The cast and crew were plagued by three major tragedies after the movie was released. The first, a composer for the movie named Krzysztof Komeda, fell off a steep, rocky slope and slipped into a coma and eventually died, resembling a death that takes place in the movie. The second involves producer William Castle, who was suddenly stricken with severe kidney stones after receiving an abundance of hate mail. While delirious in the hospital, he was heard yelling, "Rosemary, for God's sake, drop the knife!" Castle did recover, but only just barely. The third and most infamous concerns the director, Roman Polanski, and his girlfriend turned wife, Sharon Tate. Tate had lingered on set during filming and became obsessed with the occult. Later, while Rosemary's Baby was still in theaters, Tate and her unborn child were brutally murdered by the Manson family.

3 The Amityville Horror

The Amityville Horror
MGM Distribution Co.

The Amityville Horror, originally released in 1979 and then remade in 2005, is based on the real tragic event in 1974, when Ronald DeFeo Jr. shot six of his family members. The movie references this and follows a family who move into the same house. George, Kathy, and her children from a previous marriage, Greg, Matt, and Amy, begin to experience strange occurrences in the house, including Father Delaney having difficulty blessing the home due to multiple physical ailments. As the rest of the family struggle with the increasingly violent events in the house, George becomes angrier and disassociated, obsessed with the boathouse, waking up at 3:15 every night to go there. It quickly becomes clear that there is a demonic presence in the house, but it may be too late to stop it.

Both versions of the movie were filmed in private residences that were changed to look like the original house, which still exists, though the police refused to allow filming to take place there. The original cast suffered minor paranormal experiences, most notably James Brolin, who's pants mysteriously fell off their hanger in his hotel as he read the script. In the remake, Ryan Reynolds experienced the same phenomenon as his character: consistently waking up at 3:15 at night. There was also a body discovered near the boathouse where some of the filming took place.

2 The Conjuring

Warner Bros. Pictures

The Conjuring, released in 2013 and based on a true story, revolves around the Perron family, who move into a farmhouse in Rhode Island. The family includes Roger and Carolyn, as well as their five daughters, Andrea, Nancy, Christine, Cindy, and April. The paranormal activity in the house starts immediately with the clocks stopping every night at 3:07, Carolyn waking up with mysterious bruises, and their dog inexplicably dying. Concerned, Carolyn contacts demonologists Ed and Lorraine Warren, who come to find that the house used to belong to an accused witch, Bathsheba, who sacrificed her baby and killed herself at exactly 3:07. It quickly becomes necessary to perform an exorcism to save the family, as well as the Warrens.

While the Perron house does exist still, the movie was filmed in an exact replica in North Carolina. This did not stop some very terrifying paranormal experiences from haunting the set, though. Vera Farminga, who plays Lorraine Warren, found three digital claw marks on her laptop with no explanation, and, later, noticed three claw marks on her leg in the form of bruises. Joey King, the actress who played Cindy, also found mysterious bruises on her body as well, despite never injuring herself on set.

1 Annabelle

Annabelle 2 Crosses Huge Horror Milestone at the Box Office

Annabelle, another movie in The Conjuring universe that was released in 2014, tells the story of an expecting couple, John and Mia Form, who buy a vintage porcelain doll for their future daughter's nursery. The very same night, their neighbors are attacked by their estranged daughter and boyfriend who have been involved in a cult. They move over to the Form's residence and attacks them as well, but a police officer arrives on the scene to shoot the boyfriend. The neighbor's daughter picks up the porcelain doll and kills herself while holding it. It isn't until the Forms move to a new apartment and the discarded doll follows that they contact their priest and the Warrens. They realize that the two cultists summoned a demon that clung itself to the doll, all with the purpose of taking Mia's life.

The movie was filmed in L.A., while the actual locations of the events were in Santa Monica and Pasadena. The sets, however, were just as haunted. Director John Leonetti found three unexplained finger marks on a dusty window, reminiscent of the demon, who has three fingers and talons. A more serious incident happened when the actor playing the demon walked down a hallway with the actor who plays the janitor. A light fixture fell on the janitor actor's head in the same hallway that the demon kills the janitor in the movie.
