Rollicking fun with the MGM sheen at its height. Jean and Gable were always a great match and they continue here as a doxy and a ship's captain. The script is serviceable enough to not stretch belief too far, what is more fantastic is that Jean would be traveling on a China tug in white satin no matter how striking it is, same goes for Clark in his white captain uniform but that's Metro for you. This is the last of Jean's true brassy platinum blonde roles. For the short time she had left in her regrettably too brief career she softened her look and her roles were heading to the more ladylike end of the spectrum, for instance Wife vs. Secretary. Rosalind Russell is just starting out here too stuck in one of what she referred to as her Lady Mary roles, full of good diction and the graaaand manner her great flair for comedy wouldn't be tapped for several years, she's fine but knowing what she's capable of she feels constrained. The rest of the cast is terrific with Wally Beery and Robert Benchley standing out in full bodied characterizations. Keep in mind that this was made in the 30's so racism and sexism are on full display in a very casual way.

China Seas is a sort of follow-up to Red Dust, with the addition of the sort of all-star cast pioneered in Grand Hotel, only set on board a passenger ship instead of in a hotel. As in Red Dust, the central plot element involves a triangle featuring Clark Gable and Jean Harlow. However, this time the hypotenuse is occupied by Rosalind Russel rather than Mary Astor.

By the time China Seas was produced the infamous Hayes Office was already busily enforcing standards of decency in the film industry. Consequently, the action is a good deal less steamy than in Red Dust. Nevertheless, the Gable-Harlow chemistry is still very much in evidence, even if their byplay has been somewhat toned-down.

Another major element of the plot involves piracy against modern (1930s) shipping in the Far East. Some viewers might find that notion a bit far-fetched. However, it is far less absurd than one might think. In fact, it is still going on today (2012)!
