You can almost hear the grunting and straining as director Lesley Selander labors mightily to arise from the quicksand of the Saturday afternoon cowboy matinee that has been his happy place to the more rarified air of the 1950s psychological western. Ultimately, of course, Selander loses the battle and slips back into standard hero/villain, shoot em up land but it was a noble attempt and should be recognized as such. Of course, Selander isn't helped in his struggle by having around his neck the millstone of a supremely dull leading man, Robert Stack, who seemed to do decent work only when Sirk was around to direct him. And the screenplay, with its yawner of a mutiny sub plot and a most unconvincing, 180 degree switch of character on the part of Joan Taylor, is not exactly Frank Nugent or Marguerite Roberts. So let's give it a generous C plus for the scenes of survival in the desert and good support from such 50s western stalwarts as Charles McGraw, Robert Wilkie and Douglas Kennedy, among others.
