This musical is a true joy. I would place it within the 30 best musicals ever made. Some pseudo casting directors, music experts, and nit-picking purists, may disagree. I saw it recently at home with an audience which included all age groups: from a 7 year old, through a 60 year old cousin. They all agreed that they would like to see it again, some other time. To my judgment, the casting is ideal: Kathryn, fits well into the innocent damsel, who is swept off her feet, falling in love with the dashing gambler (Howard Keel). Joe E. Brown is perfect (as he makes believe his domineering wife, that he is hen-pecked) as he does what he wants, saying" yes dear. The opening sequence where we are shown the riverboat, the pier, the musical-traveling troupe, the crew of the boat, the passengers, the loading of supplies, the light cargo. The different decks of the boat, with its frills. The costumes, of the 19th century attire, are charming, and alluring to both sexes. The innocent damsel does marry the galant gambler. Katryn Grayson is believable in the travails that ensue. Ava Garner does an excellent portrayal of the suffering half-caste, who is not accepted in a white society. Agnes Morehead, is the aggresive wife of captain Joe E. Brown, who in fact inside that hard armor, is tenderness in disguise. I would venture to say that any viewer with be with a happy heart as the final credits of the film roll on. (A note to the editors): I could only get Show Boat by listing Howard Keel, as the actor. I could not get your video on Show Boat by the title of the film.
