This is from a movie of the late 1930s. But beware neither Bella Spruce nor Letty Finhadden actually appear in the movie. The female protagonist only claims these names to confuse her husband. Here’s a quote from the movie to make it easier for you to guess which movie I’m talking about:

“Why mommie, you know better than to come to a place like this your first day out of bed. What if the health officers find you? They’ll put you right back in quarantine.”
“I won’t stay in quarantine. I don’t care who catches it!”
