If you've watched many old cartoons or sitcoms from the 60s and 70s, you probably recognize the Screen Gems company ID that closed many shows like Bewitched or the Flintstones. Evidently, there's an entire subculture of people who suffer from an irrational fear of the Screen Gems stylized S and accompanying Moog jingle. Director Rodney Ascher learned of this phenomenon and interviewed many of these logophobics for a short documentary called "The S From Hell", which premiered at Sundance this year. You can watch the entire documentary below and wonder in amazement at how incredibly weird and easy to scare some people are. Be warned, the film includes extensive footage from "Halloween III".
