Luke Perry switches stripes when he segues into “The Rocky Horror Show.”

The former “Beverly Hills, 90210” star goes from playing embezzler-inmate Jeremiah Cloutier in HBO’s “Oz” to the role of squeaky-clean Brad Majors in the current Broadway revival of Richard O’Brien’s tuner about a transvestite who seduces a naive, young couple. Brad and Janet were immortalized by Barry Bostwick and Susan Sarandon in the 1975 cult film “The Rocky Horror Picture Show.”

Perry replaces Jarrod Emick in the stage show, which opened in November 2000. Produced by Jordan Roth, the production is nominated for four Tony Awards, including best revival, lead actor in a musical (Tom Hewitt), director of a musical (Christopher Ashley) and costume design (David C. Woolard). Perry’s stint in “Rocky Horror” lasts only a month, from June 26 to July 29.

Roth’s production has been distinguished by a distinctly eclectic cast, featuring a wide range of performers from the worlds of theater, rock and television. This summer, the show tips to the TV side with Perry and Ana Gasteyer of “Saturday Night Live” (replacing rocker Joan Jett on June 12) joining original cast member Dick Cavett, who continues as the show’s narrator.
