Dust Be My Destiny (1939) on TCM just now. Priscilla Lane's on the stand trying to free her man John Garfield with a heartfelt plea. It's a tearjerker, but as I was listening to her she said the word "you" in a way that seemed false, New England upper class-y, but then it didn't, and then it seemed just old movie-ish, but then I figured it was an accurate rendition of some idiomatic usage, so I tried to sound it out, maybe get a fix on it, and it was something like "yo-uh" only the second vowel is barely aspirated. And the "o" isn't really long. But there it is again. Yo-uh - which is exactly how it's spelled. That's how people said that word, at the time it first was written down. And for a long while after.
