Behind the Door

Behind the Green Door is a 1972 American pornographic film, widely considered one of the genre's "classic" pictures and one of the films that ushered in the Golden Age of Porn (1969–1984). Featuring Marilyn Chambers, who became a mainstream celebrity, it was one of the first hardcore films widely released in the United States and the feature-length directorial debut of the Mitchell brothers. Behind the Green Door was adapted from an anonymous short story of the same title, which was circulated by means of numerous carbon copies. The story's title references the 1956 hit song "Green Door", whose lyrics describe being denied entry to a raucous nightclub with a green door. Though she plays the central character, Chambers does not have a single word of dialogue. The film is possibly the first feature-length American heterosexual hardcore feature to include an interracial sex scene.
