CLEVELAND, Ohio -- Barry Bostwick’s been called “a******” for the better part of nearly 40 years now -- long enough that he’s more than OK with it.“I think I have embraced it,” the veteran actor says, quipping that, “I think it has become part of my personality. I think it’s so much a part of me I can now go run for governor of Florida...”Bostwick is not, of course, an a****** -- at least to us. But thanks to playing Brad Majors in the 1975 film “The Rocky Horror Picture Show,” it’s a sobriquet he’s carried with him due to audience participation rituals shouted nearly every time the character appears on the screen.It’s those very rituals that have made “Rocky Horror” -- an adaptation of a stage musical by British actor and playwright Richard O’Brien -- a cult classic after being a box office flop when it was released, and has allowed Bostwick to feature at comic cons and at special showings of the film like the one he’ll host on Wednesday, Oct. 16, at the Stocker Arts Center in Elyria....
