It's the sort of script that Hollywood would have called a "merry marital mixup" back when, but with a little more stuff on the curveball than usual: A suspects B and B suspects A of infidelity, so A hires C to impersonate A on a cruise, while B hires private detective D to trail A, but D thinks C is A... There are some good lines, and director Curtiz, as was his wont, keeps things moving. Janis Paige is a hoot in a series of increasingly bizarre hats, and the unusual dullness of the Warners leading men (I mean, Don DeFore?) doesn't hurt that much. Doris even manages to look enraptured opposite the slightly snarky Jack Carson, and sings "It's Magic" three times. Even Carson sings, and not badly, though it's a somewhat xenophobic mock-Trinidad specialty number that's embarrassing by today's standards. Doris, in her film debut, is assured and pleasant, and so is the movie, in a studio-manufactured kind of way.
