The Opening of Misty Beethoven (1976)

[synopsis] this film won the best picture at the first porn Film Festival (Erotic Film Festival) and was praised by many critics as the best porn film in film history. Although the popularity of mainstream audiences to see porn has waned, some directors insist on making high-quality porn films, such as Radley Metzger's "The Opening of Misty Beethoven" in 1975. The film is adapted from George Bernard Shaw's famous play "Pygmalion", or a pornographic variation of the Hollywood movie "My Fair Lady". In the film, Miss Beethoven was originally a frivolous and untidy street prostitute who usually masturbated male guests at the Paris Adult Theater, but when she met a doctor of sexology, she was transformed into an elegant social socialite and overwhelmed the crowd at the annual party of pornographic magazine publishers.
