Halloween essentials are usually limited to candy, a pumpkin or two, and some semblance of a costume. For die-hard fans of The Rocky Horror Picture Show, Halloween is also a time to stock up on rubber gloves, playing cards and toast in preparation for the screening of the 1975 cult film.

Showing monthly at the Garland Theater, “The Rocky Horror Picture Show” moves to the First Interstate Center for the Arts on Sunday as part of the film’s 49th anniversary tour, where Brad Majors (Barry Bostwick) himself will discuss the film before the screening . The tour also includes a memorabilia exhibit, a costume contest and Absolute Pleasure, a local shadow show originally founded in 1989 that has performed alongside performances at the Garland since 2013. For those who haven’t already, there will also be a “virgin” ceremony. However, the film is accompanied by a shadow cast.

Before being cast in Rocky Horror, Bostwick was known for originating the role of Danny Zuko in Grease on Broadway. Looking back, he feels both shows offered unique entertainment in their own way.

“I’ve been lucky and I’ve always been drawn to these outliers, these shows that broke the rules,” he said.

The transition from the role of Zuko, who was too cool for school, to the nerdy Majors wasn’t difficult for Bostwick, as they both found themselves similarly brash in their own worlds.

“They both have that slight twinkle in their eyes, self-aware but not making fun of their characters,” he said.

Although he had performed on Broadway before, singing for a film was a new experience for Bostwick. He and the other actors lip-synced to music they recorded before filming, which Bostwick said challenged him to know what his interpretation of the performance would be before it took place.

“We didn’t have weeks of rehearsals to make mistakes and/or change the way we wanted to do it, so we went in and boom, that was it,” he said. “In a way it comes out the best because you don’t massage it to death. It’s improvisational.”

Although the film was initially not popular with audiences or critics, the film’s presentation as a midnight movie ensured that it gained traction, as did Louis Farese Jr., Theresa Krakauskas and Amy Lazarus, who are credited with being with the Practice has begun, reacting to the film and bringing props to screenings.

The Rocky Horror Picture Show was directed by Jim Sharman and features a screenplay by Sharman and Richard O’Brien, who also played Riff-Raff. The film is based on the 1973 musical of the same name, which features music, lyrics and a book by O’Brien.

The film follows Majors (Bostwick) and Janet Weiss (Susan Sarandon), a young couple whose car breaks down near a castle. When the couple arrive at the castle, they learn that it is inhabited by costumed strangers who are having a party. The head of the castle, Dr. Frank N. Furter (Tim Curry), invites the couple to stay the evening before bringing the handsome Rocky (Peter Hinwood) to life. Lots of singing, dancing and seduction follows.

The film also stars Patricia Quinn, Nell Campbell, Jonathan Adams, Meat Loaf and Charles Gray.

Bostwick still enjoys hearing stories of people sneaking into midnight showings of “Rocky Horror,” and he remembers one day presenting a framed pair of underwear to a shadow caster (a nod to his wardrobe during a large part of the film). -closed theater in Los Angeles. He later learned that the underwear became a treasured memento and was passed from person to person.

Bostwick has fully embraced it and is now selling signed and personalized tights on barrybostwick.com.

Although Bostwick said he and the rest of the cast never imagined during filming that “Rocky Horror” would receive the response it has had since its release, he can understand the appeal since it has become a place for people is who, like the film, march there to the beat of their own drum.

“In high school, there was no club they could belong to,” he said of the fans who flocked to one performance after another. “They had to find and form their own club. That’s what I think “The Rocky Horror Picture Show” did on a Friday and Saturday night. It created its own kind of club.”

Bostwick has worked steadily since “Grease” and “Rocky Horror,” including roles in “Spin City,” “Megaforce,” a film with its own following that Bostwick is making a documentary about, and the upcoming “Daruma.” is, according to its website, “the first film in the history of American cinema to feature two authentically cast protagonists with disabilities in a narrative that is not about overcoming disability.”

He said his younger self would be proud of the hard work he put into his career and the fact that he accomplished everything he set out to do without hurting anyone while raising a family.

However, he knows that people will always associate him with “Grease” and “The Rocky Horror Picture Show,” but he’s not complaining.

“I always enjoyed it,” he said. “There was hooting and hollering, and the roar usually comes from the audience…So many people at the pre-show meet and greet come up and say, ‘Thank you for coming and doing this in our city.’ I say, “Well, thank you very much for meeting me and promoting this movement.” It’s not just a movie. I think it’s a movement.”
