These Movies All Said “Based On A True Story,” But Not All Of Them Were—Can You Guess Which Ones Were Lying To You?


Before You Trust Those Five Famous Words

There's no law that says Hollywood has to tell the truth. Countless movies say "Based on a true story..." at the beginning. Some of them accurately reconstruct documented events, while others merely borrow inspiration from real events—and a few deliberately mislead their audience for effect. 

See if you can guess which of these movies were actually based on a true story, which were loose adaptations at best—and which were just flat out lying to you.

Argo Sounds Like Hollywood Inventing Hollywood

Six Americans hide during the Iran hostage crisis while intelligence officers create a fake science-fiction movie as their escape cover. A made-up production company, false identities, and a screenplay called Argo sound almost comically cinematic. Surely Hollywood added the fake-Hollywood scheme afterward, right?

Argo: The Wildest Part Was Real

The central rescue scheme was genuine. CIA records confirm that officers created Studio Six Productions, built a fake movie project called Argo, and used it to help six U.S. diplomats leave Iran in January 1980. The real operation depended on cooperation between the United States and Canada.

The Strangers Says It Was Inspired By True Events

A couple at an isolated house is terrorized by masked intruders who seem to attack for no meaningful reason. The film explicitly tells viewers it was inspired by true events. That wording matters, because it does not necessarily mean Kristen, James, and their attackers were real people.

The Strangers: Inspired, Not Recreated

Writer-director Bryan Bertino traced the idea partly to a childhood incident when strangers knocked on homes and burglarized empty houses. He also cited the random violence of the Tate-LaBianca murders as an influence. The film’s specific home invasion and characters were created for the story.

The Fourth Kind Goes Even Further

Milla Jovovich appears as herself and tells viewers they are about to see a dramatization supported by archival footage. The movie then mixes polished scenes with supposedly genuine recordings from Nome, Alaska. That presentation sounds unusually specific, so was psychologist Abigail Tyler’s alien-abduction case actually documented?

The Fourth Kind: The Evidence Was Fabricated

No. Universal created fabricated online news stories to support the movie’s marketing, prompting a settlement involving Alaska news organizations. The film’s supposedly factual presentation was part of a deliberate reality-blurring technique rather than independent evidence that its alien-abduction story actually happened.

The Amityville Horror Starts With Something Horribly Real

A family moves into a Long Island house and soon reports terrifying supernatural activity. The address had already been the scene of a genuine mass murder, giving the later haunting claims an unusually disturbing backdrop. Does that make the movie’s supernatural story a verified true account?

The Amityville Horror: Real Horror, Disputed Haunting

Ronald DeFeo Jr. really slew six members of his family in the Amityville house in 1974. The later Lutz family haunting claims, however, have long been disputed, and residents and skeptics have described them as a hoax. The crime is factual; the paranormal story is not established fact.

The Blair Witch Project Wants You To Doubt Your Eyes

Three student filmmakers disappear in the Maryland woods, leaving only disturbing footage behind. The rough images and “recovered footage” presentation made the movie feel unlike ordinary studio horror. If you saw it early, could you tell whether the missing students and their recordings were real?

The Blair Witch Project: Fiction Disguised As Reality

The missing filmmakers and Blair Witch story were fictional. Smithsonian notes that the movie deliberately presented its shaky, imperfect footage as unedited reality, making amateur technique part of the illusion. The brilliance was not documenting a real disappearance, but making a fabricated one feel authentic.

Open Water Leaves Almost No Place To Hide

Two vacationing divers surface after a scuba trip and discover that their boat has left without them. The film’s promotion said it was based on true events, making its empty horizon even more unsettling. Did a real couple actually disappear after being abandoned at sea?

Open Water: The Central Nightmare Really Happened

Yes, although the movie necessarily invents what happened afterward. Americans Tom and Eileen Lonergan were accidentally left behind during a 1998 dive on Australia’s Great Barrier Reef and were never found. Because nobody witnessed their final hours, the film’s detailed ordeal is dramatization.

Apollo 13 Hardly Needed Hollywood To Raise The Stakes

An oxygen-tank explosion cripples a spacecraft headed for the Moon, forcing astronauts and NASA controllers to improvise a desperate route home. The events seem almost too perfectly structured for a movie. Was Ron Howard’s 1995 drama built around a genuine spaceflight crisis?

Apollo 13: Very Much A True Story

Yes. NASA records show Apollo 13 launched in April 1970 with Jim Lovell, Jack Swigert, and Fred Haise, then suffered an oxygen-tank explosion that ended the planned lunar landing. The crew ultimately returned safely after one of NASA’s most famous emergencies.

The Texas Chain Saw Massacre Sounds Like A Case File

The 1974 horror classic uses documentary-style narration and was promoted as though its gruesome events had actually happened. Leatherface, his family, and the doomed young travelers certainly feel grimly plausible. Before checking the answer, decide whether Texas ever had this exact massacre.

The Texas Chain Saw Massacre: Fiction With Real Inspiration

The titular massacre itself did not happen. The Texas State Historical Association says the plot is fictional, although Tobe Hooper and Kim Henkel drew partly on murderer and grave robber Ed Gein when shaping Leatherface. Marketing the movie as true was a deliberate promotional tactic.

Schindler’s List Carries A Different Kind Of Weight

Steven Spielberg’s drama follows German industrialist Oskar Schindler as he protects Jewish workers during the Holocaust. Because the film depicts real historical atrocities, the standard “true story” question requires care. Was Schindler’s rescue effort itself a documented part of the historical record?

Yes. Historical research shows that Schindler used his factories, connections, and bribes to help protect more than

Fargo Makes An Awfully Confident Promise

Fargo opens by declaring that its Minnesota crime story really happened in 1987 and that only the names were changed. The film then follows a car salesman whose kidnapping scheme collapses into murder. So, was Marge Gunderson really chasing these criminals through the snow?

Fargo: Mostly Fiction

Not in the way the opening card suggests. Joel Coen said the film drew generally from a real event, while the characters and story details were invented and the brothers did no detailed research. The “true story” framing was designed to change how audiences watched the thriller.

Did Any Surprise You?

It turns out that movies can just say whatever they want. Some of these movies caused genuine scandals over their use of “Based on a true story." Had any of them fooled you?
