The plot [from Will Henry's novel McKenna's Gold] is good, the acting adequate. But it's the scenery, the vastness of the west, the use of cameras, and of horses, and the special effects which keep the viewer involved and entertained.
The structure of the movie is so loose that a narrator (Victor Jory) must be employed from time to time to explain the plot, as if it were a serial. Most surprising in a movie that obviously cost a good deal of money is the sloppy matching of exterior and studio photography with miniature work for special effects.
