Inaugurated by the 1969 release of Andy Warhol "Blue Movie", the phenomenon of adult erotic films being publicly discussed by celebrities (like Johnny Carson and Bob Hope), and taken seriously by critics (like Roger Ebert), a development referred to, by Ralph Blumenthal of "The New York Times", as "porno chic", and later known as the Golden Age of Porn, began, for the first time, in modern American culture. According to award-winning author Toni Bentley, Radley Metzger 1976 film "The Opening of Misty Beethoven", based on the play "Pygmalion" by George Bernard Shaw (and its derivative, "My Fair Lady"), and due to attaining a mainstream level in storyline and sets, is considered the "crown jewel" of this 'Golden Age'.
