"Enoch Arden" has been made as a sound film four times, all comedies. (Tennyson's poem is, to say the least, tragic.) The Grant/Dunne version ("My Favorite Wife") is generally considered the best treatment. It was remade as "Move Over, Darling", with Doris Day and James Garner.
Somerset Maugham's play was filmed as "Too Many Husbands", a reasonably good film (with a "suggestive" ending) that suffers next to "Favorite". "Three for the Show" is a musical remake. At best, it's lame. At worst, it's stupid.
Either way it's a mish-mosh of mostly uninspired dance numbers, songs borrowed from other musicals, and nothing whatever that would convince us we should have the least bit of interest in the characters and their predicament. It doesn't work as comedy, drama, or spectacle.
The only good thing is an extended dance sequence in which Betty Gable and Marge Champion fight. (No mud or Jell-O, though.)
It's not only boring, but irritating. A dud all around.
