Valley of the Dolls is a 1967 American drama film based on the 1966 novel of the same name by Jacqueline Susann. ("Dolls" was a slang term for downers, originally short for dolophine, it quickly came to refer to any barbiturates such as Nembutal, used as sleep aids.) It was produced by David Weisbart and directed by Mark Robson.
Upon release it was a commercial success, though universally panned by critics. The film has gained a cult following in subsequent years.  It was re-released in 1969 following the murder of Sharon Tate, and again proved commercially viable. Co-star Parkins, attending a July 1997 screening of the film at the Castro Theatre in San Francisco, told the sold-out crowd, "I know why you like it...because it's so bad!"
In 2012, Welsh-Greek singer/songwriter Marina Diamandis, released her second album "Electra Heart", which she mentioned in an interview to be loosely based on the movie, with one of the tracks named after the film.
