Tim Curry is returning to “The Rocky Horror Picture Show” for Fox’s special. The original cast member will be the criminologist narrator in the television revival. “American Idol” alum Adam Lambert has also joined the cast.

The original Frank-N-Furter, Curry starred as the character in the 1973 London stage production of “The Rocky Horror Show” and then the Lou Adler-produced film “The Rocky Horror Picture Show,” which premiered September 26, 1975.

“I am very happy and excited to be a part of this new event,” said Curry.

Curry and Lambert joins cast members Laverne Cox, who will play Dr. Frank-N-Further, the sexually ambiguous flirtatious alien mad scientist first made famous by Curry; Victoria Justice as Janet; Ryan McCartan as Brad; Reeve Carney as Riff Raff; and Staz Nair in the title role.

“Rocky Horror” follows sweethearts Janet (Justice) and Brad (McCartan) who stumble upon Frank-N-Furter’s (Cox) bizarre abode. With the help of his faithful servants Riff Raff (Carney) and Magenta (yet to be cast), Frank-N-Furter, is holding an annual Transylvanian science convention to showcase the birth of “Rocky Horror” (Nair), a fit, attractive man created solely to fulfill Frank’s desires.

Lambert will play Eddie, who is described as the rock-n-roll loving ex-delivery boy who emerges at Dr. Frank-N-Further’s on a motorcycle and crashes the party.

“I grew up watching ‘Rocky Horror,’ but could never imagine that I would be part of this new vision,” said Lambert. “‘Rocky Horror’ always made me feel like it was OK to celebrate my weirdness. Hallelujah, bless my soul! I love that old time rock-n-roll!”

An “American Idol” alum, Lambert’s casting  keeps him in the Fox family. The singer/actor also appeared in Fox’s “Glee.”

Known for his eccentric, goth appearance and impressive pipes, Lambert competed in the eighth season of “Idol.” Though he didn’t win, he has gone onto a successful career as a musician with three studio albums and hits, including his recent single “Ghost Town.” Since 2011, the pop/electric rocker has been collaborating with Queen as lead vocalist.

A reimagining of the cult classic, which still plays in theaters, after its recent 40 year anniversary, Fox’s “Rocky Horror” special hails from Fox 21 Television Studios and Gail Berman’s Jackal Group. Lou Adler and Gail Berman will serve as exec producers with Kenny Ortega who will also direct and choreograph.

The two-hour “Rocky Horror” special airs this fall on Fox.
