Classics like Halloween, The Omen and Nightmare on Elm Street are nowhere to be seen.

Everyone has their own opinion when it comes to the scariest film ever made. What we find terrifying depends on a whole host of factors, whether it’s the “found footage” format of The Blair Witch Project, the blood-soaked slashing of Nightmare on Elm Street, or the supernatural dread of The Autopsy of Jane Doe.
Yet one film has been officially crowned the most frightening of them all, based on scientific evidence. The Science of Scare ranking of 2026 gauged people’s physiological reactions to horror films by monitoring their heart rate, heart rate variability and peak heart rate. Researchers put together a list of English-language horror films and screened them to 250 participants, recording their physical responses using heart monitors.
After gathering each film’s average heart rate increase, largest heart rate spike and heart rate drop, the figures were combined to produce a Science of Scare Score out of 100. This year’s top film achieved a score of 96. For context, Shrek holds a Scare Score of just 3, reports the Express.
However, it’s unlikely to be the film that immediately jumps to mind for most people when they think about the scariest movie of all time. Many will instinctively think of iconic classics such as The Evil Dead, The Omen, Halloween or Don’t Look Now, while others might lean towards more recent offerings like The Exorcism of Emily Rose or Paranormal Activity.
The scariest film of all time
This year’s winner, with a score of 96 out of 100, was the 2012 film Sinister. It pushed viewers’ average heart rate up by 34%. The supernatural horror film establishes its dark and menacing atmosphere from the outset, opening with old home video footage depicting a family of four standing beneath a tree with sacks over their heads and nooses around their necks. It goes on to follow the story of a true crime writer, played by Ethan Hawke, whose family relocates to a new house and uncovers a box of terrifying home movies in the attic. The film was directed by Scott Derrickson.
Séance horror Host came in second place with a score of 95, while Skinamarink claimed third with 91. The scariest new releases, meaning those that came out in 2026, were Undertone and Obsession, both of which scored just 63.
However, the biggest jump scare of all belonged to this year’s Resident Evil, which sent viewers’ heart rates soaring to 134 BPM — a staggering 70 BPM spike, the highest surge ever recorded in the project’s history. Despite this, the film failed to crack the overall top 50 scariest films.
What critics say about Sinister
Sinister may well be the most terrifying film ever made according to this experiment, yet it divided critics sharply. Writing in the Chicago Sun-Times, legendary film critic Roger Ebert described it as “an undeniably scary movie, with performances adding enough human interest to give depth to the basic building blocks of horror”.
Meanwhile, Mark Olsen, writing in the Los Angeles Times, said: “As the best horror stories so often do, Sinister makes clear that we are our own boogeymen, the worst monsters of all.”
Yet not everyone was won over. In the Toronto Star, Peter Howell claimed Sinister is “more stupid than scary” and “can’t even figure out who its real demon is”, while Michael O’Sullivan in the Washington Post wrote: “The hero of Sinister is almost unaccountably dumb. So, unfortunately, is the movie.”
