Reports are surfacing that some U.S. moviegoers have been experiencing seizures while watching Twilight: Breaking Dawn Part 1, which may be caused by photosensitive epilepsy, according to some medical experts.

Brandon Gephart, a California man, was rushed to the hospital after he got sick during the birthing scene and was rushed to hospital. ”He was convulsing, snorting, trying to breathe,” Gephart’s girlfriend Kelly Bauman told reporters. “He scared me big time.”

Needless to say, Gephart said he has no interest in seeing how the movie ends.

A Salt Lake City man, who didn’t want to reveal his name for fear of losing his job, experienced a similar seizure while watching the film.

“I didn’t really remember what happened after that,” he said. “I think I blacked out. According to [my wife] I was shaking and mumbling different noises.” His wife explained further: “I was kneeling in front of him and slapping his face.”

Medical experts say that the film’s birth scene, which features red, white and black images, could have triggered episodes of photosensitive epilepsy. ”It’s like a light going off because it hits your brain all at once,” Dr. Michael G. Chez told reporters. “The trouble with theaters is that they’re so dark, the light flashing in there is more like a strobe light.”

You know those men have got to be embarrassed about passing out in Twilight. Poor guys.
