Horror movies are scary but in some cases, the events that took place on the horror movie sets were more terrifying than the films that were produced. A number of terrifying incidents took place on the set of some of the most successful horror movies of all time, during filming or shortly afterwards. Whether these incidents were fatal accidents, cruel twists of fate or some sort of evil curse still remains debatable. 

While filming, the crew encountered certain strange occurrences. The scariest incident took place when the storage facility, where all the props were kept, caught fire and burned to the ground. Even the Dybbuk box relic, used in the movie was completely destroyed. Later, the cast and crew refused to replace the Dybbuk box since they believed that the object was cursed. 

While shooting, Jennifer Carpenter, the lead actress complained about her radio alarm clock repeatedly turning itself on during the making and every time it turned on, it only played one song on repeat – it was Alive by Pearl Jam. Even the other crew members started reporting the exact same thing. Finally, all of them collectively agreed on removing all the radios, from their hotel rooms. Thankfully, the creepy occurrences stopped but there is still no explanation to it. 

A number of vague incidents took place on the sets of the film that still remain unexplained. One day, while shooting, a strong wind came up and seemed to swirl around the Perron family but the crew members noticed that the tress opposite to them, weren’t moving. The hotel where all the crew members and the actors were staying, caught fire and everyone had to be evacuated. One night the movie director felt something strange, while he was working late in his office. One evening, his dog started growling at an unknown entity, across the room.

This film was doomed from the very beginning. During the production, Vic Morrow, one of the lead actors was killed on the sets. A year before the shooting of the film began, Morrow had already warned his family and friends about something bad that was going to happen to him on an upcoming movie. Two child actors who were hired illegally by the producers were also killed during the production of this film.  

A dead body washed up on shore, close to the set, even before the shooting started. The cast and crew were pretty shaken and shocked by this incident but they decided to go ahead with the project. As days passed by, Ryan Reynolds, the lead actor and several other crew members felt shaken when they started waking up at 3:15 am, each morning. Coincidentally, it just so happens that this is the exact time of the murders depicted in the film. 

Jack MacGowran, the actor of this film died unexpectedly, few days after finishing his scenes. A security guard and FX worker also died on the sets of this film. The entire set burnt down and it had to be rebuilt again. The director of this film got a priest along with him, to bless the area but that didn’t seem to work. When the movie was released, a number of audience members suffered from a cardiac arrest and died on the spot. 

While shooting, the lead actor found out his son had committed suicide. A crew member almost lost his life in a car accident while driving to the set. Even the scriptwriter, almost died in an airplane crash, when it was hit by lightning. Later, an airplane crash did take place, killing several members of the crew. 

While shooting, the crew members constantly felt uneasy. According to the director, TVs turned on and off without any explanation and many crew members complained about having vague, vivid dreams while filming at the Yankee Pedlar Inn; a real life haunted hotel. Ti West, the director also claims that the lead actress believed a spirit was sharing her room. 

During filming, the crew spotted eerie marks on windows in areas which hadn’t been dusted or cleaned for years. They spotted claw marks that always had three fingers, just like the demon in the movie. One of the actors also suffered a serious head injury in the same hallway he would shoot his death scene.

Heather O’Rourke, the star of the movie died at the age of 12. She suffered a cardiac arrest while she was working on the later installments of the film. Dominique Dunne, the actress who plays the older sister was also killed by her ex-boyfriend just one day after the movie was released. 

One fine day, the producer received an anonymous letter stating he was going to die from a long and painful ailment. Soon enough, he collapsed and was in need of medical emergency. But the music composer wasn’t lucky enough. He died after a nasty fall, suffering a hematoma of the brain.

While shooting a scene, Brandon Lee, son of martial arts legend Bruce Lee was killed after a prop gun malfunctioned. On the first day of shooting, a crew member was severely burnt and a construction worker accidentally impaled his hand on a screwdriver. 

While shooting, the crew repeatedly saw apparitions. One crew member was reportedly assaulted by a ghostly figure. The shooting was constantly interrupted by flickering lights, falling equipments and disembodied voices. Some of the production crew, including actor Billy Zane, heard faint voices calling out their names. 

When the filmmakers started to combine the footage, the faces of the actors became distorted and unidentified figures appeared in the shots. Filmmakers are still clueless as to why this happened or how it happened.  

Crew members complained about feeling uncomfortable, sick, heavy and uneasy on the hospital-themed set. The buzzer used to go off in one of the rooms, on the second floor or third floor, when nobody was up there. No one has any explanation for this incident.
