A week and a half ago, you may have seen our poll on RT to select the Scariest Movie Ever. Based on existing lists and RT staff ideas, we selected 40 of the scariest movies ever filmed and asked you to vote for your favorite. A British broadband service comparison website conducted a research experiment to ascertain the same thing, with startling results.

 You may disagree that The Exorcist is the scariest movie ever, yet it topped our list with 19% of the votes. The highest-grossing R-rated horror film ever and the first to be nominated for Best Picture.

 1. THE EXORCIST (1973)

 Ari Aster's Dark Family Drama, a supernatural horror film about grief, was a hit. Toni Collette's Oscar-dismissed performance as Annie was a highlight, but the film's biggest surprise was... We won't reveal that.

 2. HEREDITARY (2018)

 After directing Saw, Dead Silence, Insidious, and this chiller based on Ed and Lorraine Warren's paranormal investigations, James Wan has established himself as a horror maestro.

 3. THE CONJURING (2013)

 Numerous Stephen King novels and stories have been made into motion pictures. Some of these adaptations, including Carrie, Misery, and Pet Sematary, are still regarded as masterpieces today.

 4. THE SHINING (1980)

 With 42% of the votes cast, the top four films on this list were followed by six other films, each of which received about 3% of the vote. Put otherwise, the last six films were separated by a maximum of sixty votes.


 It's never easy to take something that works well in one culture and attempt to properly translate that formula for another, but Gore Verbinski did just that with The Ring.

 6. THE RING (2002)

 The movie that made Jamie Lee Curtis a global sensation and made John Carpenter a household name comes in at number seven on our list.

 7. HALLOWEEN (1978)

 We've finally arrived to the movie that was deemed the scariest by the "scientific study," for those of you who missed it. Director Scott Derrickson has a history of making horror movies,,,

 8. SINISTER (2012)

 Although James Wan is already farther up this list, he co-wrote this supernatural thriller about a young child who goes into a coma and starts to channel an evil spirit before he and Patrick Wilson collaborated on The Conjuring. 

 9. INSIDIOUS (2010)

 Clown phobia is a real issue, despite the fact that it feels false to admit such a thing these days. If you need further proof, consider the 2017 box office success.

 10. IT (2017)

Luis Fonsi Tried to Get Ariana Grande on ‘Despacito’ Before Justin Bieber
