This Saturday is sure to be a memorable evening at the Oriental Theatre, 2230 N. Farwell Ave. Usually the structure's Cathedral-like pillars and domes stand out enough, but tonight spectators can ogle men in spiky heels, garters and eyeliner and women with pink wigs wearing gold sequins.

Welcome to a midnight showing of "The Rocky Horror Picture Show," complete with a cast of performers to mirror the costumes and actions of Susan Sarandon or Tim Curry on screen, sing alternate versions of the movie's songs and encourage the audience to play along.

"The Rocky Horror Picture Show," a low-budget cult classic about loss of innocense and, well, aliens, has been playing regularly at the Oriental since 1978. This year the Milwaukee cast, named Sensual Daydreams, celebrates its 30th anniversary, giving the Oriental the record for the longest continuous showing.

For the past 10 years Jerry Dunk has been the cast director for Sensual Daydreams and plays Riff Raff in the production, although there was a time he thought he could never be a part of "The Rocky Horror Picture Show."

"I used to come to the show a lot, and one night one of the cast members said to me, 'When are you going to put in your application?'" Dunk said. "I didn't even think that you could join this craziness! I got an application from him and joined."

The current incarnation of the Oriental's cast has been doing the Time Warp for over 15 years.

"The name Sensual Daydreams has been used for the cast since 1992," Dunk said. "The line was taken from a line in the movie. Frank-N-Furter sings, 'Erotic nightmares beyond any measure, and sensual daydreams to treasure forever.'"

The Sensual Daydreams lineup has changed over time, even if the movie reel has stayed the same.

"There have been many changes in personnel," Dunk said. "No one from the beginning of Sensual Daydreams is still in the cast, but some of the original people do come to see the show from time to time."

Dunk said being able to call the Oriental, a Landmark Theatre, home has added excitement the Rocky Horror experience.

"The Oriental is a beautiful old movie palace," Dunk said. "They don't make places like this anymore. It is amazing to watch any movie in there, especially amazing that a bunch of loud people can throw rice, toilet paper and toast all over the place."

The Oriental's atmosphere also makes the cast take their performances seriously, Dunk said.

"Being in such a great theater and being in a cast well known for good costumes and accurate performances makes us want to do a great job," Dunk said. "The show is about having fun and is fun for us, but we try to do our parts well and keep a high level of professionalism."

Want to watch Sensual Daydreams perform at the Oriental? There are a few things a first-time Rocky participant, affectionately called a "virgin," should know.

DO:

SEE THE MOVIE ON A HOME SCREEN FIRST. This way you'll understand the jokes the cast yells at the screen.

ADMIT TO BEING A "VIRGIN." If this is your first time seeing "The Rocky Horror Picture Show" in a movie theater, you are a "virgin." You'll get a lipstick "V" drawn on your forehead and special attention from the cast.

DRESS UP. Fashioning yourself after a character from the movie could gain you free admittance to the show – the first five audience members to show up in "Rocky Horror" costumes get free

tickets. This Saturday's theme is

Valentine's Day lingerie and the cast will award prizes for outfits they deem worthy. "Dress in what you want," cast member Jerry Dunk said. "Some people dress as a characters from the movie, some dress crazy, some dress in drag, some dress normal. Do whatever you want."

SING OR DANCE ALONG TO THE SONGS, if you know them, and participate as the cast prompts you to.

BRING PROPS, or get a "Survival Kit" filled with props from the cast.

DON'T:

EXPECT TO HEAR THE MOVIE OVER THE CAST. There will be parody songs, catcalls to characters on the screen and plot

spoilers galore.

BE AFRAID OF "VIRGIN INITIATIONS." "Our 'initiations' are pretty tame. No one is made to do anything they don't want to do," Dunk said.

FORGET TO WEAR A COAT TO WAIT IN LINE AT THE ORIENTAL. This is especially

important if you're in lingerie.

GO IF STRONG LANGUAGE OFFENDS YOU.

People that are uncomfortable with rough language are better off not showing up.

BE SURPRISED when audience members are asked to dance in the aisles (or in front of the screen.)

GO OVERBOARD WITH THE PROPS. "Security will allow you to bring your own as long as it's a reasonable amount," Dunk said. "That is, a handful or two of rice per person, not a 10 pound bag. A squirt gun, but not a Super Soaker."

THROW PROPS AT THE MOVIE SCREEN OR THE CAST; they're volunteers with

responsibilities to the Oriental.

What to bring and when to use it

+Rice (to throw at the wedding scene)
