But the film’s gory birth scene, which contains rapid flashes of black and red light, has apparently also caused two men to have seizures.

Brandon Gephart of Roseville, Calif. began convulsing during the scene, according to CBS 13 in Sacramento. His girlfriend, Kelly Bauman, said he was “snorting and trying to breathe.” Gephart said he cannot remember what happened.

An unnamed Utah man said he suffered from similar symptoms.

“I didn’t really remember what happened after that I think I blacked out. According to [my wife], I was shaking and mumbling different noises,” the man told ABC 4 in Salt Lake City.

The men may be suffering from photosensitive epilepsy, a rare condition where seizures may be triggered by lights flashing in a pattern.

The Utah man, who did not want to be named over fears he would lose his job (not because he didn’t want his buddies to find out he was seeing “Twilight”), claims another person suffered similar symptoms at the same theater. The theater’s manager did not have knowledge of this, according to ABC 4.

And thus the greatest excuse to not take your significant other to a “Twilight” film was born.
