Horror movies are designed to terrify audiences with blood, gore, and screams. But sometimes, the real horror happens behind the camera. From grueling shoots to dreadful conditions, some film crews and casts have endured their own nightmares while bringing our fears to life. Here are 10 horror films where making the movie was a true ordeal.
The Blair Witch Project (1999)
The Blair Witch Project, famed for its found-footage style, was filmed over eight days of discomfort in the woods. Directors Daniel Myrick and Eduardo Sánchez aimed for maximum realism by pushing the actors to improvise their dialogue. They’d leave unsettling notes for the cast, like, “Heather, go south to escape, no arguing,” and “Josh, you’re done with this BS.”
The directors also tried to scare the actors at night by shaking their tents and playing recordings of children. Actor Joshua Leonard told the Guardian in 2018 that it was “more annoying than anything else.” According to him, the real nightmare was the high tension, hunger, discomfort, and hurt feelings. The safe word “taco” lost its appeal because it constantly reminded them of their hunger.
Midsommar (2019)
Florence Pugh and Jack Reynor praised director Ari Aster’s work on Midsommar, but the film’s disturbing themes made the shoot exceptionally tough. Pugh revealed on the Off Menu podcast that each day, “the content would be getting more weird and harder to do,” leading her to mentally “abuse my own self in order to get that performance.”
Reynor echoed this, noting the psychological burden. “It’s dark, and it’s unsettling to watch all these people around you basically making it look like they’re going to kill you in a horrific way,” he told Collider. He emphasized the difficulty, especially with the heat, insects, and general tension among the crew.
The Lighthouse (2019)
The Lighthouse, filmed in Nova Scotia at a specially built lighthouse, turned into a grueling experience. Director Robert Eggers confessed to Rolling Stone, “There were days when I wanted to die, and I love the cold.” Even the local crew, used to harsh conditions, called it the toughest shoot they’d ever done.
Robert Pattinson told Interview Magazine that the scene where he’s sprayed with water was nearly his breaking point. After the fifth take, he confronted Eggers, feeling like he was being tortured. Eggers simply replied, “I am spraying a fire hose in your face.”
The Evil Dead (1981)
Sam Raimi described The Evil Dead as the hardest thing he’d ever done in a 2009 interview. The cast and crew froze nightly without warm coats and had an industrial heater that blew out noxious fumes. With no hot water, Raimi used a coffee maker to wash fake blood off his hands so he could handle the camera.
The special effects makeup was also brutal. Tom Sullivan, the makeup artist, used acrylic paint on the actors’ faces, which had to be scrubbed off with scouring pads. Ellen Sandweiss and Betsy Baker suffered physical injuries during filming, adding to the on-set misery.
Frankenstein (1931)
Boris Karloff’s portrayal of the Monster in James Whale’s Frankenstein is iconic, but it came at a cost. Karloff endured extremely long hours, including one 25-hour shoot. The studio didn’t count the four hours for makeup application and 90 minutes for removal as part of his working hours.
Karloff also had to repeatedly carry Colin Clive up a hill and stairs in a heavy costume, which caused back problems. This treatment motivated Karloff to advocate for actors’ rights, leading him to become a founding member of the Screen Actors Guild.
The Birds (1963)
Tippi Hedren claimed in her memoir that Alfred Hitchcock mistreated her during the filming of The Birds because she rejected his advances. The scene where birds attack her was supposed to use mechanical birds. Instead, live birds were thrown at her for five days, with some even tied to her dress.
Hedren described feeling barely coherent and pushed to her limit. The crew was horrified, but only Hitchcock could stop it. After a bird nearly pecked her eye out, Hedren refused to continue. She suffered exhaustion and alleged that Hitchcock further tormented her by harming her career and sexually assaulting her.
The Shining (1980)
Stanley Kubrick’s The Shining took 56 grueling weeks to film, with Shelley Duvall suffering the most. A behind-the-scenes documentary shows Duvall in poor health due to the stress of the role, even losing hair. Kubrick showed little sympathy.
Kubrick’s demanding style, often requiring over 35 takes, combined with the intensity of her role, wore Duvall down. She recalled the staircase scene with Jack Nicholson, filmed 127 times, as particularly hard. The emotional toll led to physical rebellion, making it difficult for her to continue crying every day.
The Exorcist (1973)
Rumors of a curse surrounded The Exorcist after a fire and the deaths of nine people. Director William Friedkin believed in demonic possession due to the strange and sinister events during filming, calling it the hardest thing he’d ever done.
Friedkin’s behavior contributed to the unpleasant atmosphere. He was known for firing and rehiring crew members, slapping actors, and firing a gun to startle them. Linda Blair and Ellen Burstyn suffered long-term back problems from being thrown around during filming.
The Texas Chain Saw Massacre (1974)
The dinner scene in The Texas Chain Saw Massacre was filmed over 26 hours in sweltering heat. The set was filled with rotten food, causing cast and crew to need oxygen and vomit breaks.
Marilyn Burns, who played Sally, had an especially rough time. When a prop knife failed, Gunnar Hansen (Leatherface) actually cut her finger. Jim Siedow was encouraged to hit Burns for a scene, leading her to faint after eight takes. Burns said her hysterical laughter at the end of the movie wasn’t acting.
The Last House on the Left (1972)
Sandra Peabody, who played Mari in The Last House on the Left, feared the rape and torture scenes might become reality. David Hess admitted scaring her during one scene, even suggesting he might actually rape her. Director Wes Craven confirmed Peabody was genuinely afraid.
Marc Sheffler threatened Peabody when she struggled with a scene, holding her head over a cliff and threatening to throw her. Fearing for her life, she delivered the desired performance. This film pushed the boundaries of on-set safety and psychological distress.
Conclusion
