Kids these days. Meanwhile in the 70s: > [The Rocky Horror Picture Show] soon became a hit as a midnight movie, when audiences began participating with the film at the Waverly Theater in New York City in 1976. Audience members returned to the cinemas frequently and talked back to the screen and began dressing as the characters, spawning similar performance groups across the United States. At almost the same time, fans in costume at the King's Court Theater in Pittsburgh began performing alongside the film. This "shadow cast" mimed the actions on screen above and behind them, while lip-synching their character's lines. https://en.m.wikipedia.org/wiki/The_Rocky_Horror_Picture_Show https://en.m.wikipedia.org/wiki/The_Rocky_Horror_Picture_Sho...
