Does The Rocky Horror Picture Show need any introduction? It’s a cultural artifact with unlimited lifespan — it creates new audiences for itself each screening, and will most likely continue to be shown in theatres until the end of linear time. The plot almost doesn’t matter (but here it is in brief anyway: an engaged couple get lost and wander to a nearby castle where they are captured, kind of, by a Transylvanian doctor in lingerie and his entourage who are attempting to create a life form but are actually in some cases space aliens – it’s complicated); all that matters is the experience of seeing it and the thrill of seeing a bunch of performers totally off the leash. Of course the people on screen aren’t the only performers anymore, either. The audience owns the movie now. They sing along, dress in costume, go through lines, and act alongside the film as it plays. And if you’re a “virgin”, as first-timers are known, this is a perfect opportunity to learn what you’ve been missing all these years.
