Original Australian Daybill Movie Poster. Shock Treatment.Shock Treatment is a 1981 American black comedy musical film directed by Jim Sharman, and co-written by Sharman and Richard O'Brien. It is a follow-up to the 1975 film The Rocky Horror Picture Show. While not an outright sequel, the film does feature several characters from the previous film, most portrayed by different actors, as well as several Rocky Horror actors in new roles. The film stars Jessica Harper as Janet and Cliff De Young in a dual role as Brad and the film's main antagonist Farley Flavors, with O'Brien and Patricia Quinn playing sibling character actors.Given a limited release on the midnight movie circuit beginning on October 30, 1981, Shock Treatment was a critical and commercial failure, not earning the same level of cult film status its predecessor received. Since its release, the film has grown somewhat of a cult following. In 2015, the film was adapted as a stage production in London.
