Many TV shows draw inspiration from real events, and crime dramas are especially known for basing episodes on actual cases. You can often recognize the basis for shows like Criminal Minds or Law & Order in past criminal investigations. Mindhunter even focused directly on the stories of real serial killers. However, it’s surprising to learn that The X-Files, a show usually filled with monsters and alien encounters, also took inspiration from true stories.
Many episodes of The X-Files were inspired by real-life events, demonstrating that truth can often be more bizarre than what you find in fictional stories.
10) “Duane Barry” – Episode 2, Episode 5 – Phineas Gage
The X-Files episode “Duane Barry” drew inspiration from the real-life story of Phineas Gage, a 19th-century railroad worker who amazingly survived after a metal rod pierced his brain. However, the injury drastically altered his personality. The episode adapted this story, reimagining Gage as a former FBI agent shot during a surveillance operation, which left him emotionally unstable. Although the storyline eventually shifted to alien abduction, the initial brain injury and its resulting effects were rooted in the true story of Phineas Gage.
9) “The Erlenmeyer Flask” – Season 1, Episode 24 – Gloria Ramirez
As a movie critic, I recently revisited the early X-Files episode, “The Erlenmeyer Flask,” and it’s fascinating how much it’s rooted in a real-life, strange event from Riverside, California in ’94. The episode dives into a pretty out-there concept: scientists messing with alien DNA and attempting to combine it with human DNA. I remember being particularly struck by one scene – it features paramedics trying to save Dr. Secare, only to become poisoned themselves. It’s a genuinely unsettling moment and really highlights the dangers at the heart of the story.
The incident began with Gloria Ramirez, a patient who arrived at an emergency room with advanced cervical cancer. Shortly after, several medical staff members became critically ill and ended up in intensive care. It was discovered that Ramirez had been secretly taking an undisclosed medication. When paramedics administered oxygen, it unexpectedly caused a chemical reaction, turning the drug into a toxic airborne substance that affected everyone nearby.
8) “Home” – Season 4, Episode 2 – Ward brothers
As a huge X-Files fan, I remember the episode “Home” from season four being seriously talked about – and not in a good way! It was so disturbing, Fox actually refused to rerun it for years, and it didn’t resurface until it hit FX on cable. It was actually the first episode to carry a content warning, which gives you some idea. The story centers around Mulder and Scully investigating the tragic death of a baby born with awful deformities, and their investigation quickly leads them to the incredibly unsettling Peacock family.
Mulder and Scully uncovered a family history of incest involving the Peacock family’s mother. The episode’s storyline was inspired by the real-life case of the Ward brothers, documented in the film Brother’s Keeper. This documentary followed four isolated, elderly brothers as authorities investigated whether one was responsible for the deaths of the others. The Peacock brothers in The X-Files were directly based on this case.
7) “Paper Clip” – Season 3, Episode 2 – Operation Paperclip
The second episode of The X-Files Season 3, titled “Paper Clip,” is based on a real historical event. Operation Paperclip was a secret U.S. operation after World War II that brought scientists, engineers, and technicians from Nazi Germany to work for the American government.
An episode of The X-Files reveals that Mulder and Scully discover classified government documents suggesting a Nazi scientist brought to the U.S. after the war created human-alien hybrids. This plotline was central to the show’s Syndicate arc and drew inspiration from the historical Operation Paperclip, a real program that secretly brought German scientists to America.
6) “The Field Where I Died” – Season 4, Episode 5 – Waco
The fifth season of The X-Files featured an episode, “The Field Where I Died,” heavily influenced by the tragic events at the Waco siege involving David Koresh and his followers. The real-life incident began when ATF agents tried to execute a warrant, but the cult members were prepared, leading to a shootout that left 10 people dead, including four agents. The FBI then arrived, resulting in a 51-day standoff that ultimately ended with the deaths of 76 cult members, tragically including 20 to 28 children.
In the episode “The Field Where I Died,” Mulder investigates a cult, hoping to find a confidential source within its ranks. The investigation quickly reveals the cult’s involvement with strange, supernatural occurrences centered around the idea of reincarnation. The episode’s dramatic climax, featuring the destruction of the cult’s compound and a large number of fatalities, was heavily inspired by the real-life events that unfolded at the Waco compound.
5) “Tunguska” – Season 4, Episode 8 – 1908 Tunguska Event
The X-Files episode “Tunguska” gets its name from a real-life event. This episode, the eighth of Season 4, centers on Dana Scully and Walter Skinner being questioned at a Senate hearing regarding Fox Mulder’s disappearance. It’s the first half of a two-part story that builds on the show’s alien mythology, specifically the plotline involving the black oil.
This episode was inspired by the real-life Tunguska event of 1908—a massive explosion believed to have been caused by a meteor exploding in the atmosphere. Reports at the time suggested the meteor might have carried evidence of alien life, making it a compelling true story for The X-Files to adapt.
4) “Oubliette” – Season 3, Episode 8 – Polly Klaas
The X-Files episode “Oubliette” was inspired by a heartbreaking real event, but the show offered a more hopeful resolution than what actually happened. The story follows Mulder and Scully as they investigate the kidnapping of a teenager, who is held captive by a mentally disturbed photographer. Mulder discovers that the photographer previously kidnapped another girl, and this new victim shares a psychic connection with her.
The storyline of the kidnapping was based on the tragic case of Polly Klaas, who was 12 years old when she was abducted. In real life, her kidnapper, Richard Allen Davis, murdered her. While the X-Files episode featured a similar kidnapping, the teenage victim was saved. The show’s writers made the character older to distance the story from the real-life tragedy.
3) “Unruhe” – Season 4, Episode 4 – Ted Serios
The X-Files episode “Unruhe,” from its fourth season, was penned by Vince Gilligan, who later created Breaking Bad. The episode centers on Mulder and Scully investigating a man who kidnaps women and performs lobotomies on them. The only lead they had was a series of warped photos of the victims taken before they were kidnapped. Gilligan has stated that the story was inspired by the serial killer stories he devoured as a child.
The episode’s idea came from a man named Ted Serios, who believed he could use his mind to create images directly onto Polaroid film – he called them “thoughtographs.” While Serios himself wasn’t the basis for the episode’s villain, the concept of thoughtography drove the central mystery.
2) “Squeeze” – Season 1, Episode 3 – Richard Ramirez
The third episode of The X-Files featured a truly frightening villain, Eugene Victor Tooms. Mulder and Scully investigated a series of strange murders where the killer seemed able to contort his body to fit through incredibly small openings. This led them to suspect he was a genetic anomaly who had been committing crimes for nearly a century.
The character of Tooms, the villain in the show, was inspired by two real-life serial killers: Jack the Ripper and Richard Ramirez. Ramirez specifically committed murders across the Los Angeles and San Francisco Bay Area between 1984 and 1985, claiming the lives of at least 15 people.
1) “Irresistible” – Season 2, Episode 13 – Jeffrey Dahmer
The second season of The X-Files featured one of its most memorable episodes, “Irresistible.” This episode introduced Donnie Pfaster, a killer with a disturbing obsession, who would appear in the show one other time. It marked the first encounter between Mulder and Scully with Pfaster, who was kidnapping and murdering women. The episode also explored the lingering trauma Scully experienced after her own abduction, and how she coped with it.
An episode of The X-Files featured a scene where Scully, while hallucinating due to stress, saw a character transform into a devil. Chris Carter, the show’s creator, explained this was inspired by accounts from victims of Jeffrey Dahmer, who reported he seemed to shapeshift while they were held captive. The episode illustrated the idea that some of the most terrifying monsters are simply ordinary people.
