The Stepford Wives is a 1975 American science fiction-thriller film based on the 1972 Ira Levin novel of the same name. It was directed by Bryan Forbes with a screenplay by William Goldman, and stars Katharine Ross, Paula Prentiss, Peter Masterson, Nanette Newman, and Tina Louise.
While the film was a moderate success at the time of release, it has grown in stature as a cult film over the years. Building upon the reputation of Levin's novel, the term "Stepford Wife" has become a popular science fiction concept and several sequels were shot, as well as a remake in 2004 using the same title, but rewritten as a comedy instead of a serious horror/thriller film.
