August 14 - 1975 - The Rocky Horror Picture Show Makes Its World Premiere

The Rocky Horror Picture Show is a key cultural touchstone among a particular brand of people, with the original Rocky Horror Show theater production getting multiple revivals. Its fame as an audience participation, shadow acting midnight movie has made it bigger than simply just a normal movie. Yet when it premiered at the Rialto Theatre in London, it was a massive flop, doing so poorly that the New York City premiere had to be cancelled. After an executive convinced distributors to show it at midnight, it got a second life, which then got the extra features for which it is known.
