The Rocky Horror Picture Show began its ongoing life as a musical play in London in 1973 (The Rocky Horror Show). Creator Richard O'Brien had recently quit the cast of Jesus Christ Superstar, and passed the time between acting jobs by writing a rock musical which truly entertained him. Combining elements of Alice Cooper, Frankenstein, the fifties revival and the sexual revolution, O'Brien and his creative team (including Superstar director Jim Sharman and set designer Brian Thomson, producer Michael White and acting friend Tim Curry) produced a runaway stage hit. The play won awards and ran for seven years in London (it's currently on tour in England) and was produced all over the world. Lou Adler brought the play to his Roxy Theatre in L.A. in 1974, intending to introduce it to a major studio for a film version. The film was produced in England at Hammer's Bray Studios and the nearby Oakley Court castle in Berkshire, using most of the British cast and Americans Susan Sarandon, Barry Bostwick and Meat Loaf, and was released in London in August 1975. The USA release the following month came after a disappointingly short run of the play on Broadway. Briefly test-marketed in the states, The Rocky Horror Picture Show flopped, and 20th Century-Fox decided to recoup some of its production costs by showing it as a midnight movie in April 1976. Early Rocky fans in New York began performing "audience participation," ranging from joking in response to the dialogue and singing along to acting out the film in costume in front of the screen. Fox released more prints as the New York and L.A. scenes got media attention, and the film was soon playing in over 250 theaters across the country. After years of midnight showings, the film became one of the top five highest-grossing musicals in U.S. release, and one of the few to earn more than $100 million. The 2006 DVD release includes the original two-disc set released in 2000. The first disc contains the film, with the option of viewing UK or USA versions (the UK version includes the complete "Superheroes" song, while the USA version edits out two verses), commentary by Richard O'Brien and Patricia Quinn, and an optional "audience participation" track. The second disc contains supplementary material, including the 1995 36-minute documentary (made for the laserdisc) featuring interviews with O'Brien, Sharman, Thomson, Adler and most of the film cast; outtakes from the film; 1999 cast interviews from VH1's "Behind the Music"; trailers and more. Shock Treatment was touted in 1981 as being "not a sequel, not a prequel, but an equal to The Rocky Horror Picture Show." It more closely resembles a musical sequel, using the Brad and Janet characters (played by new actors) in an ironically prescient "reality TV" setting where fast-food magnate Farley Flavors controls Denton USA, a giant TV studio. Brad and Janet appear on the game show "Marriage Maze," hosted by blind Viennese Bert Schnick (Barry Humphries, creator of Dame Edna). Rocky alumni O'Brien, Patricia Quinn, Nell Campbell and Charles Gray appear, with many of the Rocky crew behind the scenes, including director Jim Sharman. The songs, hybrids of Rocky Horror meets new wave, are ambitious but somewhat strained. Shock Treatment never took off with most Rocky fans, and can be viewed today as a fun early 80s artifact with its own set of fans. Richard O'Brien's musical followup is notable for its use of the creative team behind the unique success of The Rocky Horror Picture Show.
