It's not just Andrews in The Sound of Music. Others in the cast have English accents or English-tinged accents or mid-Atlantic accents while others have Americans.
We can look at the film version of Fiddler on the Roof as a film with a melange of accents, even more so than The Sound of Music. And then there is Gigi, with Chevalier and Caron sounding French, Jourdan having a British tinge to his accent but it doesn't necessarily sound like French was his first language, Gingold and Jeans (and John Abbott) sounding very English, and Eva Gabor sounding Hungarian.
In films where the characters are understood to be speaking a language other than English but we are hearing them in English, it often seems like anything goes. |
