A great story and a great cast. If you set aside all the early Hollywood traps about racism and sexism, this is a terrific and watchable romance/adventure.
The story is very similar to Gable's later film, "Mogambo." He's the adventurous cad who loves two women - a beautiful ice-queen who represents his link to civilization (Russell); and the cute but stubborn and uncouth "woman of the world" who has the capacity to betray him when it suits her (Harlow). This movie is very well acted. I've always said that if you give Gable an affectation to fall back on, he does extremely well. Here, he's a barking sea captain, which, almost by accident, gives his performance a better range than it otherwise would have. I don't really like Harlow, but she's good in her role.
The editing is a bit strange - many closeups are too obviously added in later, but I guess I can partially forgive this because of the time it was made. It really shows how Harlow was on a roll when she was with the rest of the cast, though. Because these individual shots do not fit in with the movie at all.
There's some amazing effects during the typhoon sequence, with a steam engine running loose on the deck - and you actually see people get run over and flattened. It's disconcerting even though you realize the camera tricks involved. Very inventive for its day.
