NEW YORK (CBS) Fans of "The Rocky Horror Picture Show" mark a big milestone today - they've been doing the "Time Warp" for 35 years.

The cult classic celebrated the anniversary of its premiere in U.S. theaters - Sept. 26, 1975 - on Sunday.

The rock opera, a parody of science fiction and B movies, still plays to masses at midnight showings, where people dress up, dance and throw designated props (rice, confetti, toast) during specific scenes in the film.

And it's getting new life on the small screen, too - "Glee" is planning a "Rocky Horror"-themed episode to air near Halloween.

Barry Bostwick and Meatloaf, who played Brad Majors and Eddie in the original film, are reportedly set to appear on the show.

Susan Sarandon, who played Janet Weiss, expressed interestin appearing, but no deals have been done. As for Dr. Frank-N-Furter, one of the "Glee" cast members will have to put on the fishnets - Tim Curry's rep said he won't be participating.

There's also a star-filled tribute in the works. The special performance, which is for charity, takes place on Oct. 28 in Los Angeles and will feature "Glee" co-stars Lea Michele and Matthew Morrison as Brad and Janet, Jack Nicholson and Danny DeVito splitting the role of the Criminologist and Jason Segal playing Dr. Everett Scott. A costume ball is set to follow the show.
