Judy (played by Patricia Ellis) can't pay her rent and has just a few hours to vacate her apartment in quite possibly the most polite eviction I've ever seen. Judy comes up with a plan to stay in the presently vacated apartment of Mr. Hale, a man she was supposed to meet for a business meeting to discuss composing. When she answers his phone, she hears opportunity knocking! That's not the only thing knocking... her new neighbor, Bob McKay, played by the handsome Warren Hull, continually knocks on the walls to quite her and she knocks back! This starts a continuing feud between the two until they eventually discover they are working together. The continually flustered Clyde Lyons (William Newell) adds several points of comedic relief to the movie. The story is smart and sweet plus the music is lovely. At about the 12:00 mark you hear the music (about a minute and a half long) for "Don't Ever Change" (Written by Walter Hirsch and Lou Handman). I really loved this piece and swear I've heard it before, though I've never seen the movie. Later in the movie it is sung by Warren Hull at the 22:30 mark. Another fun song was "Two Hearts Are Dancing" (same authors) sung by Ellis and Hull at the end of the movie.
My only complaint about Judy was her tendency to get dramatically nervous and want to flee, though she never does. Just a little odd.
I would watch it again. I watched it free with Amazon Prime, but as of this writing, I also found it on you-tube in full. It's only 53 minutes (1937 BLACK AND WHITE), so you can certainly pop in your headphones and squeeze it on your lunch hour, and then go back to work a happy camper!
