Oddly enough, My Fair Lady was the musical adaptation of Pygmalion. Then they decided to make a movie based on My Fair Lady, not Pygmalion (which is odd, since My Fair Lady is based on Pygmalion). They did this even though Pygmalion and My Fair Lady had been adapted into movie versions (one a musical, the a straight movie). This movie was called Educating Rita.

Another movie that was based on Pygmalion/My Fair Lady was Born Yesterday. They later on remade this film with Melanie Griffith and Don Johnson.
