Stranded in a terrible rainstorm, virginal suburbanites Brad (Bostwick) and Janet (Sarandon) seek refuge in a foreboding castle nearby.

But the bizarre residents of the gothic mansion have plans other than simply providing 'sanctuary.'

Led by a mad scientist/transsexual transvestite named Frank-n-Furter (Curry), and flanked by his creepy hunchback assistant Riff Raff (o'Brien) and oddball squeaker Magenta (Quinn), the unusual hosts plan to teach innocent Brad and Janet a thing or two about life, sex, perverse science, cannibalism...and interplanetary travel.

Based on the 1973 stage musical from composer Richard O'Brien, director Sharman does a spendid job here of capturing the feel of 1950s sci-fi terrors, B movies and cult flicks - all wrapped in a loving, low budget/indie vibe.

And it's buoyed by bravura performances (Curry steals the show), catchy lyrics, and infectious melodies (Sweet Transvestite and I'm Going Home are excellent).

The whole enterprise is visionary. Yes, we said 'visionary.'

Followed by a sequel Shock Treatment (1981).
