Attention creatures of the night: it’s been 40 years since the release of the cult classic film, The Rocky Horror Picture Show. On Saturday, October 22nd, Mesa Arts Center is hosting a 40th anniversary film screening party, complete with audience participation, a costume contest, and a post-show Q & A with Barry Bostwick, aka “Brad Majors,” one of the film’s original actors.

The film became a midnight movie classic after its release in 1975. Audience participation emerged as a big part of the experience with many viewing the film over and over again, shouting out snarky retorts to the actors’ lines and doing all manner of crazy things, from throwing popcorn and confetti at the screen to shooting squirt guns at the appropriate time. Some of the more theatrically-inclined regulars dressed up as film characters and formed “shadow casts” to mimic the on-screen performance. At Mesa Arts Center’s event, audience members are encouraged to dress up as their favorite character, put their hands on their hips and do the “Time Warp” to celebrate in traditional fashion. After the screening, Bostwick will answer questions about what it was like to create this unusual film and work with actors Susan Sarandon, Tim Curry and more.

The show begins at 7:30pm on October 22nd at the Ikeda Theater at the Mesa Arts Center. Tickets range from $42-$87. To purchase tickets or get more information, click here.

If you can’t make it to MAC’s 40th anniversary party, the movie is also playing at a handful of local theaters on the weekends leading up to Halloween, including AMC Ahwatukee, Centerpoint, Mesa Grand, Arizona Center, Desert Ridge and Deer Valley.

Fox is also planning to air a two-hour remake of the movie on Thursday, October 20th, and they’ve posted a very helpful Virgin’s Guide to Watching Rocky Horror for those who’ve never watched or participated.
