It’s a terrible movie.

Yet every October, hundreds of people in Iowa City flock to the Englert to watch the Rocky Horror Picture Show. Costumes, shouting, throwing, and singing are the norm, and this year will be no exception. At 11:59 p.m.

Saturday, the Englert Theater, 221 E. Washington St., and Comics in Action will bring The Rocky Horror Picture Show to life. Admission is $16.

With such an odd movie, why the cult following?

“It’s just the campiness of it,” said Noelle McVey, who will play Columbia. “There are movies I like because of the way they are, because of that sort of vintage campiness.”

Midnight screenings of the movie actually helped to increase its fan base.

“The movie itself didn’t do very well,” said Dennis Lambing of Comics in Action, who will play Brad at the Englert. “Some guy out in New York decided to kill some time and for some reason, Rocky Horror as a midnight movie somehow appealed, and people were going to the movie all the time. It became this really interesting talk-back film.”
