From flower girl to beautiful lady, Audrey Hepburn did just as much transformation as Eliza Doolittle in My Fair Lady, George Cukor's 1964 screen version of the 1956 musical play, by Alan J. Lerner and Frederick Loewe, which was an adaptation from George Bernard Shaw's 1913 play Pygmalion. I thought that Hepburn played the role wonderfully bringing grace to Doolittle after Higgins' work but maintaining the ill-mannered Cockney girl previous to her meeting with him.
Although the part of the flower girl was just as crucial to the role, Hepburn absolutely shined after Doolittle turned into a Hungarian princess. It is not hard to imagine Hepburn as a princess; she could easily fool any professional. Hepburn was easily adaptable to the role because of her ability to draw people to the character. Everyone has to fall in love with Eliza Doolittle; with Hepburn in the role there really was no other option.
However, I did not care for the chemistry between Hepburn and Harrison. I felt that Higgins' character should have had just as much charm as Doolittle, and I did not find Harrison as appealing as Hepburn, which tarnished their chemistry. Yet all in all, My Fair Lady struck an international audience, and Hepburn helped a great deal in the role of a transformed flower girl.
