At least two people began convulsing during the birth scene in the Twilight Saga’s "Breaking Down," according to media reports.

The first man is California resident Brandon Gephart who said the scene triggered an incident when he attended the movie, causing him to convulse, reports The Wrap.

His girlfriend Kelly Bauman said he was "convulsing, snorting, trying to breathe," according to the report.

Another man who watched the movie in Salt Lake City experienced the same symptoms during the same scene, according to Salt Lake City's ABC 4 News.

"I didn't really remember what happened after that I think I blacked out. According to her I was shaking and mumbling different noises," the man who preferred to be anonymous told ABC News.

In the so called "gore" scene, Kristen Stewart's character gives "violent" birth to a baby half-human, half-vampire. But the scene also features sudden bursts of light that are known to trigger "photosensitive epilepsy" that can cause mini-seizures in a viewer, according to the Epilepsy Therapy's Project website.

The brains of people who have certain kind of sensitivity and are exposed to this type of visual stimulation have their brain produce epileptic-like discharges, according to the project.

The most popular example of photosensitivity occurred in Japan in 1997 when nearly 700 children were admitted to hospitals, mostly because of seizures that occurred while watching the popular cartoon Pokémon, according to the Epilepsy Therapy's Project.
