This was one of those B-movie Westerns John Wayne had to pay his dues, and learn his craft in, on his way to superstardom and becoming a household name. His acting chops, while coming along and becoming more multidimensional, are still developing, and he gets by more or less on his charisma and big smile. Joseph Kane provides decent, pedestrian direction--all of the exciting scenes are directed by Wayne's longtime associate, Yakima Canutt (the one who would later direct the outstanding chariot race in 'Ben-Hur: A Tale of the Christ'), and Vera Ralston is great as the loving wife who just seems to do the wrong thing at the worst possible time.
Ward Bond and Mike Mazurki are excellent as the bad guys, and Walter Brennan (as the most bipolar ship captain one will EVER find in cinema) and Nick Stewart (as his harped-on assistant) steal every scene they're in. Ona Munson even throws in an entertaining song-and-dance number, and provides an interesting love possibility for Wayne, if he wasn't such a one-woman guy.
This was released on Christmas Day in the States, and it's no lump of coal in one's stocking, but a small, likable gift for fans of the genre. Worth a watch if you like Westerns, and a purchase and rewatch for Wayne enthusiasts.
