If you’re a fan of horror, chances are you’ve seen plenty of scary movies. Between the classics and newer fare, gory slashers and ghost hauntings, horror movies are known for their creative stories and chilling adversaries. What you might not realize is that many of these stories originally began in books.

Horror fiction is a rich source of movie adaptations. While not every book-to-screen version is successful, there are movies that manage to not only follow the source material but even elevate it. After watching these horror movies ranked by their individual fear factor, you might want to give the books a try!

10 'Jaws' (1975)

In a resort town in New England, beachgoers are under attack by a fearsome great white shark. A shark hunter (Robert Shaw), a marine biologist (Richard Dreyfuss), and the police chief (Roy Schneider) work together to catch the creature before more people are killed.

Steven Spielberg's Jaws is a thrilling summer horror movie adapted from the book of the same name by Peter Benchley. The movie differs in a few ways from the book, but the dangerous threat of the shark is frighteningly similar. Going to the beach will never be the same again!

9 'I Know What You Did Last Summer' (1997)

A year after accidentally running over a man and dumping his body, four friends reunite when one of them receives a threat. They realize that someone knows what they did, and they are all in danger of being killed one by one.

The iconic '90s horror movie I Know What You Did Last Summer is loosely based on the YA novel of the same name by Lois Duncan. While the book is mystery-based with a surprising identity reveal, the movie is a bloodier, slasher horror where every character could be a victim. It also spawned a franchise with two sequels and a TV show.

8 'The Ruins' (2008)

Four friends are vacationing in Mexico when they meet a fellow tourist searching for his brother. His last known location is at an archeological dig in the jungle. They venture into the area and reach the ruins of a Mayan temple, where they face a dangerous enemy.

Based on the horror book of the same name by Scott Smith, The Ruins is adrenaline-fueled survival horror. The screenplay is written by the book’s author, though the movie is different in several ways compared to its source. Gory and relentless, it will make you never want to step into the jungle.

7 'No One Gets Out Alive' (2021)

After her mother’s death, Ambar (Cristina Rodlo) relocates to the U.S. from Mexico. Undocumented and desperate, she moves into a gloomy boarding house run by Red (Marc Menchaca), who demands payment upfront. Creepy things start happening, and she finds herself trapped in a hellhole.

Netflix’s No One Gets Out Alive is adapted from Adam Nevill’s award-winning novel of the same name but gives its own twist on the story. Instead of a British setting, the main character in the movie is a Mexican immigrant trying to survive alone in an American city. The horrors come from the human and the supernatural in this moody tale of vengeance. Be warned: It's a horror movie that will make you fear your neighbors.

6 'The Ring' (2002)

After four teenagers died in mysterious circumstances, a reporter (Naomi Watts) investigates the case. She discovers that they watched a videotape filled with nightmarish images one week before their deaths. Curious, she decides to watch the tape, and now she has just seven days to solve the mystery.

It’s well-known that The Ring is an American remake of the Japanese horror movie Ring. But both stories originated from the 1991 novel by Koji Suzuki. The book and original Japanese movie lean towards paranormal and psychic elements, while the American version is a more straightforward scarefest.

Collider Exclusive · Horror Survival Quiz Which Horror Villain Do You Have the Best Chance of Surviving? Jason Voorhees · Michael Myers · Freddy Krueger · Pennywise · Chucky

Five killers. Five completely different ways to die — if you're not smart enough, fast enough, or self-aware enough to avoid it. Only one of them is the villain your particular set of instincts gives you a fighting chance against. Eight questions will figure out which one.

TEST YOUR SURVIVAL →

01

Something feels wrong. You can't explain it — you just know. What do you do? First instincts are the difference between the survivor and the first act casualty.

ALeave immediately. I don't need to understand a threat to respect it. BStay quiet and observe. If I can see it, I can understand it. If I can understand it, I can avoid it. CStay awake. Whatever this is, I am not going to sleep until I feel safe again. DConfront it directly. Fear grows in the dark — I'd rather know what I'm dealing with. ECheck everything, trust nothing. The threat might be closer than I think — and smaller.

NEXT QUESTION →

02

Where are you most likely to find yourself when things go wrong? Setting is everything in horror. Where you are determines which rules apply.

ASomewhere remote — a cabin, a campsite, off the grid and away from people. BA quiet suburban neighbourhood where nothing ever happens. Except tonight. CIn my own head — the most dangerous place of all, depending on what's already in there. DWherever children are — because something about this place attracts the worst things. ESomewhere ordinary — a house, a toy store, a place where the last thing you'd expect is a threat.

NEXT QUESTION →

03

What is your most reliable survival asset? Every survivor has a quality the villain didn't account for. What's yours?

APhysical fitness — I can run, I can swim, I can outlast something that relies on brute persistence. BSpatial awareness — I always know the exits, the hiding spots, the fastest route out. CPsychological resilience — I've faced my worst fears before. They don't have the same power over me. DEmotional steadiness — I don't panic. Panic is what gets you caught. EScepticism — I don't underestimate threats because of how they look. Size is irrelevant.

NEXT QUESTION →

04

What kind of fear is hardest for you to fight through? Knowing your weakness is the first step to not dying because of it.

AThe unstoppable — something that will not stop, cannot be reasoned with, and is always getting closer. BThe invisible — a threat I can feel but can't locate, watching from somewhere I can't see. CThe psychological — something that uses my own mind and memories against me. DThe unknowable — something ancient, shapeless, that feeds on the fear itself. EThe mundane — a threat so ordinary-looking that no one will believe me until it's too late.

NEXT QUESTION →

05

You're with a group when things start going wrong. What's your role? Horror movies are brutally clear about who survives group situations and who doesn't.

AThe one who says "we need to leave" first — and means it, even when no one listens. BThe one who stays quiet, watches the others, and figures out the pattern before anyone else does. CThe one who holds the group together when panic sets in — because someone has to. DThe one who asks the questions nobody wants to ask — because ignoring them gets people killed. EThe one who takes the threat seriously when everyone else is laughing it off.

NEXT QUESTION →

06

What's the horror movie mistake you're most likely to make? Honest self-assessment is a survival skill. Denial is not.

AGoing back for someone — I know I shouldn't, but I can't leave them behind. BAssuming I'm safe once I've found a hiding spot. That's when it finds me. CFalling asleep when I absolutely cannot afford to. Exhaustion is its own enemy. DLetting my curiosity override my instincts — I always need to understand what I'm dealing with. EDismissing the threat because of how it looks. That's exactly what it wants.

NEXT QUESTION →

07

What's your best weapon against something that can't be stopped by conventional means? Every horror villain has a weakness. The survivors are always the ones who find it.

AThe environment itself — I use the terrain, the water, the geography against it. BPatience — I wait, I watch, and I strike at the one moment it doesn't expect. CLucidity — if I can stay in control of my own mind, it loses its primary weapon. DCourage — facing it directly, refusing to run, taking away the fear it feeds on. EImprovisation — I use whatever's at hand, however unconventional. Creativity over brute force.

NEXT QUESTION →

08

It's the final scene. You're the last one standing. How did you make it? The final survivor always has a reason. What's yours?

AI kept moving. I never stopped, never hid for too long, never let it corner me. BI figured out the pattern before anyone else did — and I used it against the thing following it. CI stayed awake, stayed lucid, and refused to give it the one thing it needed most. DI stopped being afraid of it. And the moment I did, everything changed. EI took it seriously from the start — and I never once made the mistake of underestimating it.

Your Survival Odds Have Been Calculated Your Best Chance Is Against…

Your instincts, your strengths, and your particular way of thinking under pressure point to one villain you actually have a fighting chance against. Everyone else — good luck.

Jason Voorhees

Jason is relentless, but he is also predictable — and that is the gap you would exploit.

• He moves in straight lines toward his target. He doesn't strategise, doesn't adapt, doesn't outsmart. He simply pursues.
• Your ability to keep moving, use the environment, and resist the panic that freezes most victims gives you a genuine edge.
• The Crystal Lake survivors were always the ones who stopped running in circles and started thinking about terrain, water, and distance.
• You think like that. Which means Jason, for all his indestructibility, would face someone who simply refused to be where he expected.

Michael Myers

Michael watches before he moves. He is patient, methodical, and almost impossible to detect — until it's too late for anyone who isn't paying close enough attention.

• But you are paying attention. You notice the shape in the window, the car parked slightly wrong, the silence where there should be sound.
• Michael's power lies in the invisibility of ordinary suburbia — the fact that nothing ever looks wrong until it already is.
• Your spatial awareness and instinct to map every room, every exit, and every shadow before you need them is precisely the quality Laurie Strode had.
• You are not a victim waiting to happen. You are someone who already suspects something is wrong — and acts on it.

Freddy Krueger

Freddy wins by getting inside your head — using your own fears, your own memories, your own subconscious as weapons against you. That strategy requires a target who can be destabilised.

• You are harder to destabilise than most. You've faced uncomfortable truths about yourself and you haven't looked away.
• The survivors on Elm Street were always the ones who understood what was happening and chose to face it rather than flee from it.
• Freddy's greatest weakness is that his power evaporates in the presence of someone who refuses to give him the fear he feeds on.
• Your psychological resilience — the ability to stay grounded when reality itself becomes unreliable — is exactly the quality that keeps you alive here.

Pennywise

Pennywise is ancient, shapeshifting, and feeds on terror — but it has one critical vulnerability: it cannot function against someone who genuinely stops being afraid of it.

• The Losers Club didn't survive because they were braver than everyone else. They survived because they faced their fears together, and faced them honestly.
• You ask the questions others avoid. You look directly at what frightens you rather than turning away.
• That directness — the refusal to let fear fester in the dark — is Pennywise's worst nightmare.
• It chose the wrong target when it chose you. You are exactly the kind of person whose fear tastes like nothing at all.

Chucky

Chucky's greatest advantage is that nobody takes him seriously until it's already too late. He exploits the gap between how something looks and what it actually is.

• You don't have that gap. You take threats seriously regardless of how they present — and you never make the mistake of underestimating something because of its size or appearance.
• Chucky relies on surprise, on the delay between recognition and response. You close that delay faster than almost anyone.
• Your instinct to treat every unfamiliar thing with appropriate scepticism — rather than dismissing it because it seems absurd — is the exact quality that keeps you breathing.
• Against Chucky, not laughing is already winning. You are very good at not laughing.

5 'The Amityville Horror' (1979)

Image via American International Pictures

The Lutz family moves into a new house in Amityville, New York. Unbeknownst to them, a mass murder was committed on that property just a year before. Soon the family is affected by sudden illnesses, things moving on their own, and horrible nightmares. They have to battle a malevolent force to survive.

The Amityville Horror is based on the book of the same name by Jay Anson, which is allegedly based on a true story. The book was embroiled in controversy due to questions about its accuracy, but it hasn’t stopped various movie adaptations from being made. After the 1979 movie, there have been more than a dozen movies inspired by the events in Amityville.

4 'The Woman in Black' (2012)

In 1906, a widowed lawyer (Daniel Radcliffe) travels to a village to collect documents left by a client. He hears weird noises and sees visions of a woman dressed in all black. Terrible accidents start happening to the village children. He learns that there’s a vengeful spirit wanting to kill those children.

The Woman in Black is adapted from the 1983 book of the same name by Susan Hill. It was previously adapted into a TV movie and a stage play. The 2012 movie differs from the book in the structure and ending, but retains the haunting influence of the title character. It’s a gothic ghost tale that doesn’t guarantee a happy ending.

3 'Psycho' (1960)

A secretary (Janet Leigh) is on the run after stealing money from her boss. During a heavy rainstorm, she stops at a motel where she meets the polite but reclusive owner (Anthony Perkins). She overhears his conversation with his mother, but she has no idea the secrets he keeps.

Alfred Hitchcock's Psycho is famous for its killer shower scene and shocking ending. These ideas came from the book Psycho by Robert Bloch. While the movie adaptation is pretty faithful, it enhances the material through suspenseful scenes and masterful acting from Perkins.

2 'Rosemary's Baby' (1968)

Image via Paramount Pictures

A pregnant woman (Mia Farrow) suspects that her elderly neighbors have bad intentions toward her. She becomes convinced that they are Satanic cult members and that they want her baby for their rituals. When her husband ignores her concerns, she decides to seek help from the outside.

Rosemary’s Baby is based on Ira Levin’s acclaimed psychological horror novel of the same name. Served by Farrow's committed performance, it looks at a cult's controlling power as well as motherhood through a paranoid lens. Though some scenes are cut for brevity, the movie is overall a faithful adaptation.

1 'The Exorcist' (1973)

Chris (Ellen Burstyn) notices that her child Regan (Linda Blair) has started behaving strangely, including speaking in tongues and showing abnormal strength. She contacts the church and asks for help to save her daughter. Two priests are sent to perform an exorcism, but it’s not as easy as they believed.

Considered to be one of the scariest horror movies ever made, The Exorcist is based on the best-selling book by William Peter Blatty, inspired by a real-life exorcism case in the 1940s. The author himself adapted the book for the screen, which kick-started a franchise that includes numerous movies and a TV series.
