The trailer for Other Mommy debuted ahead of screenings of Christopher Nolan’s The Odyssey, and social media was soon flooded with stories from moviegoers who had been thoroughly freaked out by Jessica Chastain’s new horror film.
Once the trailer made its way online, it became pretty obvious which moment had audiences practically pissing their pants in theaters. Jessica, you’re scary! And also very bendy.
Of course, what terrifies one person might barely register for another, but the reaction got me thinking about the horror trailers that have genuinely unsettled me over the years. With that in mind, let’s take a look at some of the scariest movie trailers ever made.
Without a single line of spoken dialogue—or even a clear glimpse of the xenomorph—the trailer for Alien remains iconic for a reason. It begins slowly, with the unsettling image of an egg cracking open in space, before launching into a frantic barrage of screaming crew members, shadowy corridors, flashing lights, and chaotic glimpses of the Nostromo. All the while, a piercing, siren-like sound builds to an unbearable crescendo.
Then comes the legendary tagline: “In space, no one can hear you scream.”
Beyond being deeply unnerving, the trailer also accomplishes exactly what any great trailer should: it leaves you desperate to see the movie just to find out what the f*** is going on.
“Something beyond comprehension is happening to a little girl on this street, in this house.”
The first trailer for The Exorcist proved nearly as controversial as the film itself. It opens with Father Merrin arriving at Regan’s home, then immediately assaults the viewer with a barrage of black-and-white, stroboscopic images: demonic faces flashing out of the darkness, accompanied by a frantic, discordant score.
Just imagine sitting in a packed theater as those horrifying faces suddenly blast across the screen amid bursts of flashing light. Pure nightmare fuel.
According to the stories surrounding its release, the combination of disturbing imagery and unsettling music was so intense that some audience members reportedly became physically ill. The trailer was eventually pulled from theaters following complaints that its rapid flashes could trigger seizures.
It’s also notable for featuring music by Lalo Schifrin, the film’s original composer, whose score was ultimately rejected by director William Friedkin.
I never would have thought that a simple pair of clapping hands could be terrifying, but here we are. Rather than piling one scare on top of another, the trailer for James Wan’s The Conjuring takes its time, building unbearable suspense while leaving plenty to the imagination.
It follows Carolyn Perron (Lili Taylor) as she plays “hide-and-clap” with her daughters inside their new home. Blindfolded, Carolyn follows the sound of clapping into a closet, believing one of the girls is hiding inside. Of course, the audience already knows that whatever is making that sound probably isn’t one of her children.
Later that night, Carolyn hears what she assumes are her daughters playing, only to discover them fast asleep. The clapping begins again, drawing her toward the basement. The door suddenly slams in her face, leaving her trapped in the darkness with nothing but a match to illuminate whatever might be lurking below.
What follows is one of the simplest—and most effective—jump scares in modern horror. No elaborate monster reveal. No barrage of gore. Just two hands emerging from the darkness at exactly the right moment.
According to a 2020 study, Sinister is the scariest movie ever made, so it stands to reason that its trailer would be pretty damn frightening as well.
Participants were fitted with heart-rate monitors while watching a selection of horror movies. Their average resting heart rate was 65 beats per minute, but during Sinister, it climbed to 86 BPM, a 32% increase and the highest recorded by the study.
The trailer builds its unsettling atmosphere around the film’s Super 8 home movies. We watch Ethan Hawke load reels of seemingly innocent family outings, only for the footage to abruptly reveal something far more horrifying, accompanied by distorted industrial bass, demonic hums, and bursts of nightmarish imagery.
More than anything, the trailer creates the deeply uncomfortable feeling that you’ve stumbled across something you were never meant to see.
I vividly remember seeing the red-band trailer for Fede Álvarez’s Evil Dead in theaters. I couldn’t tell you which movie I was there to watch, but this trailer definitely left a stronger impression.
The moment that really stuck with me comes near the end, when Mia drags her tongue across an X-Acto knife, splitting it in two, before French-kissing her friend. Awful. Absolutely awful.
While most of the trailers on this list rely on creeping dread, eerie imagery, and the occasional jump scare, Evil Dead goes straight for the throat with pure, unrelenting brutality. This wasn’t the Evil Dead audiences had grown accustomed to. It was still drenched in blood, but there wasn’t a wisecrack—or even a hint of camp—in sight.

As I mentioned at the start, one person’s fright is another person’s yawn, so I’m aware many of you may have very different opinions on what constitutes an effective horror trailer. So let us know what you consider to be the scariest movie trailers ever made in the comments!
