PROMETHEUS
While watching Ridley Scott’s Alien prequel, an Australian teenager had a seizure and was rushed to the hospital. The offending scene: When Noomi Rapace’s Dr. Shaw slices an alien parasite out of her own stomach. Apparently, the 3D is super-real.

THE EXORCIST
A little girl possessed by a demon, who vomits profusely and stabs herself in ... sensitive places was too much for one bloke who, allegedly, fainted and broke his jaw when he hit the seat in front of him. (He later sued Warner Bros., claiming that subliminal images buried in the film caused him to faint. The suit was settled out of court.)

AVATAR
James Cameron’s global blockbuster killed a Taiwanese fan: A combination of the film’s exciting moments—and the moviegoer’s high blood pressure and hypertension—caused a fatal stroke.

V/H/S
An ambulance was called to a Sundance screening of this horror anthology when an attendee fainted. Of course, the air is a bit thin up there.

THE HUMAN CENTIPEDE II (FULL SEQUENCE)
Another film festival claimed a horrific casualty as a woman fainted at the 2011 Fantastic Fest while watching this sequel to that movie where they stitched people together in a perverted daisy chain because, well, it seemed like a good idea at the time.

FREAKS
Tod Browning didn’t have much of a career after this movie, which peered inside the world of circus freaks. The film was so extreme that when MGM tested the film, one audience member allegedly miscarried. A third of the film was trimmed; among the lost footage was a graphic circumcision.

CLOVERFIELD AND THE BLAIR WITCH PROJECT
It’s not so much that the subject matter of these two flicks revolted viewers—one, about a giant monster attack and the other, about amateur documentarians investigating a deep-woods ghost story—it was the found-footage filmmaking style. And all that jittery camera movement upset the occasional tummy.

THE TWILIGHT SAGA: BREAKING DAWN
Watching this installment of the sparkle-vamp odyssey was enough to make one Utah fella have a seizure. According to his wife, her husband—who wants to remain anonymous—"started mumbling and he was blinking on and off with his eyes at that point. I was kneeling in front of him slapping his face."

TEXAS CHAINSAW MASSACRE (1974)
Tobe Hooper’s seminal horror flick was so brutal and uncompromising, it prompted mass walkouts. No telling if those people then walked to the hospital, but they were clearly moved to a physical reaction.

PHANTOM OF THE OPERA (1925)
Apparently, the sight of Lon Cheney’s made-up face once he drops the Phantom’s mask sent female moviegoers shrieking up the aisles. And there wasn’t even any music yet.

VAN DIEMEN’S LAND
The true story of an inmate in a Tasmanian penal colony who escaped with some cronies and then, apparently, ate them caused a few New Zealanders to lose their lunches and a few others to pass out. Wimps.

PSYCHO (1962)
The notorious shower scene was the source of the intestinal distress: When Marion Crane (Janet Leigh) turned into a cross-dresser’s pincushion, viewers were said to have either vomited, fainted, ran from the theater ... or all three.

GRACE
Another Sundance movie strikes again, prompting two people to faint: This time, it’s a movie described by Slashfilm thusly: “A young woman [Jordan Ladd] has an accident in the penultimate month of her pregnancy, sadly resulting in the death of her unborn child. She decides to carry the baby to full term and deliver it, but at birth, the child appears to be miraculously resurrected. Soon she learns that the infant has a taste for human blood.”

PARANORMAL ACTIVITY
As we reported back in 2010: “Emergency services in Naples were called in at the weekend by people complaining of palpitations and anxiety after watching the film, the nearly bloodless story of a young couple trying to capture video evidence of a supernatural presence in their home. ... One 14-year-old girl was in such a state of shock that she had to be given oxygen outside the cinema.”
