EXCLUSIVE: Adam Lambert Channels Meat Loaf Behind the Scenes of the 'Rocky Horror Picture Show' TV Remake:

Adam Lambert is taking over for Meat Loaf in Fox's TV reimagining of the 1975 cult classic, The Rocky Horror Picture Show, and ET experienced all the Transylvania madness during a visit to the set!

Lambert dons a punk Elvis/zombie look for the role of Eddie in the remake, jumping off stages and singing "Hot Patootie."

"Eddie is a horndog," Lambert told ET. "He's nasty."

Joining Lambert is Laverne Cox, Victoria Justice, Ryan McCartan, Annaleigh Ashford and Christina Milian.

"I'm starring in it, so it has to be really sexy," said Cox, who stars as Dr. Frank-N-Furter, originally played by Tim Curry. "The scale of the production is so huge. It's top-notch."

The two-hour television event follows a young couple whose car troubles lead them to stumble upon an annual Transylvanian science convention held by Dr. Frank-N-Furter.

Justice and McCartan play the two sweethearts originally depicted by a young Susan Sarandon and Barry Bostwick. Actor and singer Staz Nair plays Rocky Horror, the muscle-bound specimen created by Dr. Frank-N-Furter.

"This is the only industry where my job interview requires me to come in my boxers and dance," Nair pointed out.

The Rocky Horror Picture Show premieres Oct. 20 on Fox.
