If you‘ve seen The Rocky Horror Picture Show (or even just the poster for the movie) you’ve seen those famous disembodied lips, which sing the song over the film’s opening credits. But did you know the lips belong to actress Patricia Quinn, who also plays Magenta? It’s true, but that’s not Quinn’s voice emanating from those bright red lips. In fact, the voice you hear is that of Richard O’Brien, the creator of The Rocky Horror Show and the actor who plays Riff Raff. That’s just one of the horrific facts featured in the last installment of You Think You Know Movies!

The Rocky Horror Picture Show was a flop on its initial release, but it quickly developed a cult audience, who invented the audience participation rules that have become part of midnight movie rituals ever since. Among the film’s many legions of fans was the late Princess Diana, who supposedly told Tim Curry that watching Rocky Horror “quite completed my education.” Well all right, then.
