shocking horror movie moments that elicit audible gasps from viewers are unexpected twists that make them reassess everything.

One of the most iconic horror movies that will always be classics feature characters who you'd never guess were actually the villains all along.

10 Orphan (2009)

Directed by Jaume Collet-Serra

Jaume Collet-Serra most recently directed Carry-On, one of the best thriller movies of 2024. Long before that, he had started his career by directing House of Wax and the forgettable sequel Goal II: Living the Dream before breaking through as a director with Orphan, which is also Isabelle Fuhrman's acting breakout movie. The movie follows a bereaved couple who adopt a 9-year-old orphan, Esther, after they lose their baby.

While she doesn't get along with their early adolescent older son, Esther doesn't seem to struggle to blend into the family. She starts behaving in a few alarming ways, gradually raising suspicions about her innocence. Esther's erratic behavior drives a wedge between the couple, and it becomes clear that she's the movie's villain. It is revealed in the third act that Esther is an adult woman with proportional dwarfism caused by a hormonal deficiency. You never see the revelation coming, and it changes everything about the film up to that point.

9 Happy Death Day (2017)

Directed by Christopher Landon

Christopher Landon, who wrote three Paranormal Activity movies and was slated to direct the new Scream movie before leaving that production, wrote and directed the slasher duology Happy Death Day and Happy Death Day 2U. Both of them follow Theresa "Tree" Gelbman, who gets stuck, in the first movie, in a Groundhog Day-like time loop, and keeps getting murdered on her birthday. She has to figure out the identity of the killer to avoid them, and also learn to become a better person along the way.

The whodunnit format is executed perfectly, as possibilities get eliminated gradually and the stakes consistently ramp up because feasible suspects become personally closer to Tree. Moreover, the fact that there's an actual serial killer at large makes the mystery even harder to solve. The best part is that Tree inevitably has to introspect to eliminate possible motives, and her character growth is directly linked to the mystery. By the time she figures out it's her jealous roommate, viewers will feel frustrated along with her, at how many guesses were wrong, but the unexpected twist makes up for that.

8 The Boy (2016)

Directed by William Brent Bell

We all know her as Maggie Greene, a role that The Walking Dead actress reprised after season 11, but Lauren Cohan has been working in the horror genre from even before the AMC zombie apocalypse show began. So, it's not surprising that her sparse feature film career also includes at least one horror title. Cohan plays an unsuspecting nanny in The Boy, who finds out, after taking the job, that she is to take care of a doll that her employers treat like their son.

The doll, called Brahms after the couple's son, returns in the sequel Brahms: The Boy II, but that film follows unrelated people haunted by the doll.

It is later revealed that their actual son died 20 years ago as an 8-year-old in a house fire after a girl he was friends with was discovered with her skull bashed in. The nanny is given rules to follow while looking after the doll, but she doesn't take them seriously until spooked by some inexplicable phenomena and realizes the doll only moves when she isn't looking. However, it turns out that the boy hadn't died 20 years ago, and is living as an adult within the house's walls. This twist left me with my jaw on the floor in shock.

7 Psycho (1960)

Directed by Alfred Hitchcock

Alfred Hitchcock has perhaps had the biggest impact on the horror genre in America than any other director before him. He introduced new camera angles, scoring techniques, blocking methods, and acting-focused writing in his films, which continue to influence filmmakers today. It's hard to pick his best work, but his most notorious is an easy answer – the 1960 horror film Psycho. That shower scene changed cinema forever by introducing the idea that such a safe space can host brutal violence and the trope of misleading people about who is the film's protagonist.

Norman Bates is introduced as a soft-spoken gentlemanly motel owner in Psycho, who reveres his mother and respects his customers' boundaries. His mother sounds ungrateful and overtly suspicious. She doesn't trust the motel's guests, and it is heavily implied that she kills female customers Norman interacts with. No one expects to find out that Norman's mother is long dead, and he dresses up as her and does what he imagines she would. While the explanation for his behavior has aged poorly, Psycho is a classic black-and-white horror movie that still holds up today because the twist is timeless.

6 Us (2019)

Directed by Jordan Peele

2019 was one of the best years in movie history, and for modern horror movie buffs, it was a particularly exciting year. Ari Aster, Robert Eggers, and Jordan Peele released their sophomore directorial features that year. Jordan Peele delivered Us, a horror movie that explores the nature and impact of privilege in America. It follows Adelaide Wilson, played by Lupita Nyong'o, a mute woman who lost her ability to speak after going through a harrowing experience at a funhouse years ago as a child when she encountered another girl who looked exactly like her.

I would never have guessed that the doppelgänger wasn't the villain, and the current Adelaide was actually her Tethered version.

The two of them meet 33 years later when Adelaide, as an adult, goes on vacation with her family. Her doppelgänger has her own family, who all resemble her family, and they call themselves the Tethered. The Tethered characters try to kill their counterparts, but Adelaide is able to escape with her son. I would never have guessed that the doppelgänger wasn't the villain, and the current Adelaide was actually her Tethered version. She'd replaced the original Adelaide years ago after attacking her, for the privilege of living above ground and having a fulfilling life.

5 The Others (2001)

Directed by Alejandro Amenábar

Just a couple of years after M. Night Shyamalan hit audiences with the most spoiled plot twist of all time, it was Nicole Kidman's turn to play an unsuspecting ghost. However, the two circumstances aren't nearly as similar as this comparison might suggest because Kidman's character, Grace, is actually a villain in The Others. Grace lives in a remote house alone with her children and mourns her husband, who died in the war.

After the family spots unwelcome visitors in their house, Grace becomes convinced they're being haunted. She starts investigating, and to her shock, she realizes that the household help have all been long dead. It doesn't take her long to realize that she and her children are the ghosts haunting the visitors, who are the current residents of their house. In a moment of hopelessness, Grace had smothered her children to death and killed herself in her grief after she'd learned about her husband's death. This horrifying and unexpected twist suddenly makes all the inexplicable details fall into place.

4 Scream (1996)

Directed by Wes Craven

Right from his introduction in the first scene of the film, it's clear that Ghostface is supernaturally fast because he goes from one door to another in next to no time. He runs through the house before claiming his second victim, the presumed protagonist played by Drew Barrymore. Clad in a black shroud and an iconic ghost mask, he terrorizes his victims by catching them unawares even after they have seemingly escaped him. Moreover, the most obvious suspects seem to have an airtight alibi for at least one kill.

There are always multiple people who become Ghostface in the Scream movies, except for Roman Bridger in Scream III, who's the only solo Ghostface to date.

It would never occur to anyone, but the moment it's revealed that there are two different Ghostfaces, a lot of his seemingly unnatural abilities become understandable. Billy Loomis and Stu Macher would commonly go to hunt down their victims together and would take turns doing the killing, depending on who wanted to do it more and who had the better opportunity. Ghostface is a horror movie character who helped reshape genre expectations, because he's a long-running franchise villain who's simply a placeholder, and is simultaneously his own character.

3 Saw (2004)

Directed by James Wan

Written by Leigh Whannell, who also plays one of the protagonists in the film, Saw is a great crime movie where the villain wins in the end. However, the nature of the victory changes the life of any first-time Saw viewer. The film follows two men who wake up in a dilapidated bathroom and are given a series of objects and a tape recording each, giving them instructions on what to do if they don't want to incur horrible personal losses. While they seem to initially be strangers, the characters are slowly revealed to be connected to each other.

The characters decide to put their differences aside and investigate the corpse in the middle of the room so they can figure a way out. It's clear that they've been caught by the Jigsaw Killer, who's watching them. In the final scene, the corpse shockingly stands up and reveals himself to be John Kramer, the Jigsaw Killer. This insane twist introduces audiences to the meticulous mind of Kramer, who had made it impossible for him to intervene once things were set in motion because he's that confident in his ability to read people.

2 Get Out (2017)

Directed by Jordan Peele

Jordan Peele, known for his series of skits with Keegan-Michael Key, as the comedy duo Key & Peele, broke through in Hollywood as a horror director with Get Out, arguably the best horror movie in the past 10 years. Based on the collective anxieties about systemic racism in the USA, it uses a reference to the country's history of slavery to tackle the issue. Get Out follows Daniel Kaluuya's Chris on a trip to his girlfriend's house, where he meets considerably racist relatives during a social gathering.

It's nigh impossible to predict she's in on her family's plan to kidnap Chris to be their personal servant.

Allison Williams, as his girlfriend, is so convincing in her role of being a ive partner, that it's almost impossible to predict she's in on her family's plan to kidnap Chris to be their personal servant. Peele masterfully uses this misdirection to voice a growing concern in today's world about hidden conservative attitudes in people who present open-minded personas. The amount of mistrust in the country is so bad that one can never be sure if even the helpful and likable neighbor is secretly a racist.

1 Bodies Bodies Bodies (2022)

Directed by Halina Reijn

The best horror movies address contemporary cultural norms and collective sources of fear. So, Bodies Bodies Bodies exploring its Gen Z characters' paranoia about each other, feels like a commentary on the generation's growing mistrust in a world where people are chronically online and frequently encounter misinformation. These characters are supposed to be close friends, but don't have any faith in each other, and all secretly resent each other, based on the personas they project online.

When one of them, played by Pete Davidson, is found stabbed with a sword, the group, despite initially trying, fails to present a united front and attack each other. The claustrophobic slasher seems impossible to solve as probable suspects all have alibis and get killed nonetheless. Who would have guessed that filming a TikTok is what led to Davidson's character's death when he failed to juggle a sword? Bodies Bodies Bodies possibly features the best villain twist, in that there isn't one. The real villain is their obsession with social media, and inability to ground themselves in reality.
