What Scary Movies Are Based On A True Story

Ever scream into your popcorn watching a scary movie, then wonder, "Could this actually happen?" Well, buckle up, buttercup, because some of your favorite fright fests are loosely (or sometimes not-so-loosely) based on real events. Get ready to see your favorite scary movies from a whole new, slightly less terrifying, perspective.
The "Based On A True Story" Hall of Fame
The Exorcist: Pizza Not Included, Sadly
Okay, so nobody spun their head 360 degrees (probably). But The Exorcist, that granddaddy of demonic possession movies, drew inspiration from the real-life case of a young boy known as "Roland Doe" in the 1940s.
He allegedly underwent several exorcisms. Imagine the awkward small talk with the priest afterward: "So, about that pea soup..."

The Amityville Horror: House Hunting Nightmares
Picture this: you find a gorgeous house, dirt cheap. Score! Then you find out a family was brutally murdered there. Less score. The Amityville Horror is based on the Lutz family's claims of paranormal activity after they moved into a house where a mass shooting had occurred.
Whether it's ghosts or just seriously drafty windows, those Lutzes did not get their security deposit back.
"Get out!" - The house (allegedly)

Psycho: Mom Issues On A Whole New Level
Alfred Hitchcock's Psycho gave us all shower anxieties. Norman Bates and his… unique relationship with his mother were inspired by the crimes of Ed Gein.
Gein, a Wisconsin farmer, was a grave robber and murderer who fashioned trophies from the bodies of the deceased. Forget scrapbooking; this guy was on a whole other level of crafting.
Open Water: Left High and Dry, Literally
This one is truly chilling. Open Water tells the story of a couple accidentally abandoned by a scuba diving tour boat. And guess what? It happened to someone in real life.

Tom and Eileen Lonergan were left behind in the Great Barrier Reef. Talk about a vacation buzzkill!
When Reality Bites (Back)
It's important to remember that "based on a true story" doesn't always mean a perfect recreation of events. Filmmakers often take creative liberties to heighten the drama, scare the audience, and, well, sell tickets.

So, while the kernel of truth might be there, the final product can be a wildly exaggerated version of reality. Like adding a dash of ghost pepper to your popcorn – you get the gist, but it's definitely got some extra spice.
The Texas Chainsaw Massacre: Leatherface's Inspirations
Again, blame Ed Gein! While Leatherface didn't literally exist, Gein's gruesome habits inspired the character.
The film took elements from the shocking real-life crimes, blending them into a terrifying cinematic experience. But still, it's fiction; just try not to think about it while driving through rural Texas.

Wolf Creek: Outback Horrors
The Australian outback can be a beautiful and dangerous place. Wolf Creek taps into the latter, drawing inspiration from the backpacker murders committed by Ivan Milat in the 1990s.
The film, while fictional, captures the isolation and vulnerability of travelers, making it all the more unsettling. Pro tip: Maybe skip the solo camping trip after watching this one.
So, the next time you're watching a scary movie and that "based on a true story" tagline pops up, remember to take it with a grain of salt (and maybe a shot of courage). But also know that sometimes, the scariest stories are the ones that started in reality. Now, if you'll excuse me, I need to check all the locks… twice.
