Two sci-fi horror spoofs.
In The Rocky Horror Picture Show (1975), when bland engaged couple Brad (Barry Bostwick) and Janet (Susan Sarandon) seek shelter after their car breaks down in a storm, they find themselves made welcome in the very weird home of mad scientist Dr Frank N. Furter (Tim Curry), an alien transvestite who is building a monster called Rocky. The film was written by Richard O'Brien, who co-stars as sinister singing butler Riff-Raff, and songs include the immortal 'Time Warp' and 'Sweet Transvestite'.
Shock Treatment (1981) is the sequel to The Rocky Horror Picture Show and stars Cliff De Young and Jessica Harper as Brad and Janet, who find themselves contestants--or rather prisoners--on a TV gameshow.
