“It’s astounding! Time is fleeting! Madness takes control!” Brad and Janet (Barry Bostwick and Sarandon) play two squares who stumble upon the bizarre residence of Dr. Frank-N-Furter (Curry). The all-time midnight movie classic, Jim Sharman’s riotous adaptation of a failed stage show, nearly met the same fate until it was resurrected by late-night film fanatics who incorporated an unforgettable interactive element. Peter Hinwood portrays the unwitting eponymous robot designed to relieve the transvestite doctor’s “tension,” and very loosely modeled on the idealized monster men of yesteryear.
