Wonderful mix of music, romance and comedy but I concede a trifle too long, the length however acceptable with these two. Jeanette MacDonald could do everything; sing beautifully, act as well and surprisingly (I just watched this one after many years) a gifted dancer. MacDonald and Jones are quite compatible and I can see where, had fate taken a hand, it could have been these two and not Nelson Eddy, not to downgrade Nelson's resonant baritone in any way. Allan Jones was a better actor, and was one of the finest tenors in movie history. There was one brief comic bit I found hilarious -- it was so short it may have been overlooked by many. Don Diego (Allan Jones) is singing the famous Donkey Serenade to MacDonald as she rides along in a coach. He sings the line "But try as she may, in her voice there's a flaw", to this jibe at her voice, Jeanette's displeasure shows in a grimace! The expert supporting cast is up to MGM'S standards; Warren William, Billy Gilbert, George Zucco, Douglas Dumbrille, Henry Daniell and even a one-line appearance by Ralph Byrd (a.k.a. Dick Tracy in the 1940's). I highly recommend this film, especially to fans of light operetta. The music is delightful and Jeanette and Allan give it their all. Jones' last appearance was a 1980 role on the Love Boat TV program. Upon retirement from the screen (big screen and little) he became a dentist, quite a surprise. I wonder if he sang for his patients? If he did I'm sure his waiting list was the envy of his fellow dentists.
