The Rocky Horror Picture Show is a 1975 musical comedy horror film directed by Jim Sharman. The screenplay was written by Sharman and actor Richard O'Brien, who is also a member of the cast. The production is a parody tribute to the science fiction and horror B movies of the 1930s through to the early 1960s. Along with O'Brien, the film stars Tim Curry, Susan Sarandon, and Barry Bostwick and is narrated by Charles Gray. Shock Treatment is a 1981 follow-up to the 1975 film The Rocky Horror Picture Show also directed by Jim Sharman, and co-written by Sharman and Richard O'Brien. 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.
