This 1939 take on 'Cinderella' works like a charm, and I honestly would never have guessed as much. I found myself being continuously bewitched by it, its sincerely touching and funny script and dialogue, the wealth of small character parts from the laconic spinster teacher ("Old maids are only happy when they cry, you'll find out") and the personable servants to the zany rich family that Durbin's orphan girl has to stand up to.
And of course, over and above everything else, there is Deanna Durbin, a full-fledged young leading lady with a miraculous voice and loads of screen presence and pathos (listen to her sing 'Un bel dì' from 'Madame Butterfly' at the end!). Blonde hunk Robert Stack has his first part ever as the Prince Charming who is left with the empty slipper, but only after a gorgeous series of incredibly romantic encounters.
