My Fair Lady is a 1964 American musical drama film adapted from the 1956 Lerner and Loewe stage musical based on George Bernard Shaw's 1913 stage play Pygmalion. With a screenplay by Alan Jay Lerner and directed by George Cukor, the film depicts a poor Cockney flower-seller named Eliza Doolittle who overhears an arrogant phonetics professor, Henry Higgins, as he casually wagers that he could teach her to speak "proper" English, thereby making her presentable in the high society of Edwardian London.
The film stars Audrey Hepburn as Eliza Doolittle and Rex Harrison as Henry Higgins, with Stanley Holloway, Gladys Cooper and Wilfrid Hyde-White in supporting roles. A critical and commercial success, it became the second highest-grossing film of 1964 and won eight Academy Awards, including Best Picture, Best Actor, and Best Director. In 1998, the American Film Institute named it the 91st greatest American film of all time. In 2006 it was ranked eighth in the AFI's Greatest Movie Musicals list.
In 2018, the film was selected for preservation in the United States National Film Registry by the Library of Congress as being "culturally, historically, or aesthetically significant."
