Factual error: In the Ascot racing scene, the actors' heads move from their left to right when the horses come to the winning line. From the stands at Ascot, the horses run clockwise around the track and would enter from right to left.
My Fair Lady (1964)
1 factual error
Directed by: George Cukor
Starring: Audrey Hepburn, Rex Harrison, Wilfrid Hyde-White, Stanley Holloway
Visible crew/equipment: When Professor Higgins is having Eliza practice saying the letter H by blowing into a tube to make the flame waver, the paper she's holding is actually Rex Harrison's lines. Once the paper starts to burn and the camera angle changes, you can read them and it's practically all of his lines for the whole scene.
Landlady: ...and what things does she want? Her bird cage and her Chinese fan. But she says, never mind about sending any clothes.
Trivia: Audrey Hepburn was not the only voice that was dubbed. The actor who plays Freddy had his voice dubbed as well, so in their scene together with the song 'show me' neither of them are singing.
Question: Why would Zoltan Karpathy think that Audrey Hepburn is "born Hungarian, possibly of royal birth" when her name is Eliza Doolittle?
Answer: He knows that Professor Higgins is trying to pull a fast one by having Eliza pretend to be someone else, and he fancies himself as much of a linguistic expert as Higgins. He's correct that there's something going on; he just gets the wrong end of the stick and assumes she's "high born," thus proving Higgins right that he could "train" Eliza to pass as upper class.
