Trivia: My Fair Lady
- AFIS 100 Years Series:
- Hey, It's That Guy!: Eliza is followed home by Sherlock Holmes who then proceeds to sing in the street for several days (albeit in somebody else's voice).
- Non-Singing Voice: Marni Nixon did most of Audrey Hepburn's singing for the movie; this is at least partially responsible for the Award Snub. And no, Marni Nixon's name appeared nowhere in the original credits.
- However, when video of Hepburn's original vocal performances was released in the 1990's, many fans found Nixon's overdubbing to be completely unnecessary.
- Also, Jeremy Brett as Freddy was dubbed by Bill Shirley (AKA Roger (singing) and Prince Philip).
- Out of all of them, Brett was the one who could sing. Look him up on YouTube. But his singing voice was thought too mature for Freddy.
- Rex Harrison had to avert this for himself. He explained to the production that he never performed a song the same way twice, and therefore would be unable to provide realistic lip-synching for a song he performed earlier in a studio. To accommodate, he was fitted with a wireless microphone in his tie and his songs were recorded as he performed them. When you watch him in the film, that's actually him singing at that moment. (Though Rex Harrison couldn't actually sing either, but he developed a sort of recitative to compensate.)
- What Could Have Been: When 20th Century Fox hired Don Bluth to direct an animated movie for them, they said he could helm an Animated Adaptation of either My Fair Lady, or Marcelle Maurette's Anastasia. Bluth picked the latter.
